instructions. + + The `configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, a file +`config.cache' that saves the results of its tests to speed up +reconfiguring, and a file `config.log' containing compiler output +(useful mainly for debugging `configure'). + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If at some point `config.cache' +contains results you don't want to keep, you may remove or edit it. + + The file `configure.in' is used to create `configure' by a program +called `autoconf'. You only need `configure.in' if you want to change +it or regenerate `configure' using a newer version of `autoconf'. + +The simplest way to compile this package is: + + 1. `cd' to the directory containing the package's source code and type + `./configure' to configure the package for your system. If you're + using `csh' on an old version of System V, you might need to type + `sh ./configure' instead to prevent `csh' from trying to execute + `configure' itself. + + Running `configure' takes a while. While running, it prints some + messages telling which features it is checking for. + + For installation to KDE 2.x you don't need to specify the version. + For installation to KDE 1.x use : + ./configure --with-kde-version=1 + + REMEMBER: often you have to + use also --prefix= and --with-qt-dir= to specify the pathes + AND: + once you have used ./configure the pathes are in the cache file + (config.cache), so if you want to change the configuration to + use it with another KDE version, you have to delete config.cache + first. + + 2. Type `make' to compile the package. + + 3. Type `make install' to install the programs and any data files and + documentation. + + 4. You can remove the program binaries and object files from the + source code directory by typing `make clean'. + +Compilers and Options +===================== + + Some systems require unusual options for compilation or linking that +the `configure' script does not know about. You can give `configure' +initial values for variables by setting them in the environment. Using +a Bourne-compatible shell, you can do that on the command line like +this: + CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure + +Or on systems that have the `env' program, you can do it like this: + env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure + +Compiling For Multiple Architectures +==================================== + + You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you must use a version of `make' that +supports the `VPATH' variable, such as GNU `make'. `cd' to the +directory where you want the object files and executables to go and run +the `configure' script. `configure' automatically checks for the +source code in the directory that `configure' is in and in `..'. + + If you have to use a `make' that does not supports the `VPATH' +variable, you have to compile the package for one architecture at a time +in the source code directory. After you have installed the package for +one architecture, use `make distclean' before reconfiguring for another +architecture. + +Installation Names +================== + + By default, `make install' will install the package's files in +`/usr/local/bin', `/usr/local/man', etc. You can specify an +installation prefix other than `/usr/local' by giving `configure' the +option `--prefix=PATH'. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +give `configure' the option `--exec-prefix=PATH', the package will use +PATH as the prefix for installing programs and libraries. +Documentation and other data files will still use the regular prefix. + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + +Optional Features +================= + + Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + +Specifying the System Type +========================== + + There may be some features `configure' can not figure out +automatically, but needs to determine by the type of host the package +will run on. Usually `configure' can figure that out, but if it prints +a message saying it can not guess the host type, give it the +`--host=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name with three fields: + CPU-COMPANY-SYSTEM + +See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the host type. + + If you are building compiler tools for cross-compiling, you can also +use the `--target=TYPE' option to select the type of system they will +produce code for and the `--build=TYPE' option to select the type of +system on which you are compiling the package. + +Sharing Defaults +================ + + If you want to set default values for `configure' scripts to share, +you can create a site shell script called `config.site' that gives +default values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Operation Controls +================== + + `configure' recognizes the following options to control how it +operates. + +`--cache-file=FILE' + Use and save the results of the tests in FILE instead of + `./config.cache'. Set FILE to `/dev/null' to disable caching, for + debugging `configure'. + +`--help' + Print a summary of the options to `configure', and exit. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made. + +`--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + `configure' can determine that directory automatically. + +`--version' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`--with-kde-version=(1|2)' + Specify the kde version of the installation. + +`configure' also accepts some other, not widely useful, options. + diff --git a/Makefile.am b/Makefile.am new file mode 100644 index 0000000..ce2af59

Arrays.

+
+
+Arrays can be created from any of the C data types +int, +float, +char. I start with int and +float +as these are the easiest to understand. Then move onto int +and float +multi dimentional arrays and finally char arrays + + + +
+

int and float arrays

+To define an integer or +floating point variable you would say. +
+	main()
+	{
+	  int   Count;		/* integer variable 		*/
+	  float Miles;		/* floating point variable	*/
+	}
+
+The syntax for an array is: +
+	main()
+	{
+	  int   Count[5];	/* 5 element integer array	*/
+	  float Miles[10];	/* 10 element floating point array */
+	}
+
+ +Now, the important fact is that the elements start at 0 (ZERO), so, +'Count' above has elements 0, 1, 2, 3, 4.

+To change the value of the 5th element we would code: +

+	main()
+	{
+	  int Count[5];
+	  Count[4] = 20;	/* code 4 to update the 5th element */
+	}
+
+ +If we want to initalise 'Count' at definition we can say: +
+	main()
+	{
+	  int i;
+	  int Count[5]={10, 20, 30};
+	  for (i=0; i< 5; i++)
+      	  {
+   	    printf("%d ", Count[i]);
+   	  }
+	  puts("");
+	}
+
+ +The result will be: +
+	10 20 30 0 0 
+
+We can see from the example above that the elements that have NOT been +initalised +have been set to zero.

+One last thing to show you. If all the elements are being +initialized when the variable is being defined, the compiler can work out +the number of elements for you. So this example will create an array +with 3 elements. +

+	main()
+	{
+	  int i;
+	  int Count[]={10, 20, 30};
+	}
+
+ +Don't forget, all the stuff so far also applies to float. +

+ + +

+

Two dimensional int and float arrays.

+ +C does not actually support multi-dimensional arrays, but you can +emulate them. +
+	main()
+	{
+	  int Count[5];
+	  int Matrix[10][4];
+	}
+
+Count has been seen before, it defines an array of 5 elements.

+Matrix is defined as 10 arrays, all with 4 elements.

+To initalise Matrix at definition, you would code the following. +

+	main()
+	{
+	  int Matrix[4][2]={{1, 2},
+	  		    {3, 4},
+			    {5, 6},
+			    {7, 8}};
+	}
+
+Dont forget the last element will be Matrix[3][1] +

+ + +

+

char arrays.

+ +char arrays work in the same way as int and float +
+	main()
+	{
+	  char Letter;
+	  char Letters[10];
+	}
+
+'Letter' can only hold one character but 'the 'Letters' array could hold 10. +It is important to think of 'char' as an array and NOT a string.

+To initalise 'char' variables you can use the following syntax. +

+	main()
+	{
+	  char Letter='x';
+	  char Letters[10]='f','a','x',' ','m','o','d','e','m','\0';
+	  char Text[10]="fax modem";
+	}
+
+Note that the double quotes mean 'text string' and so they will add the +NULL +automatically. This is the only time that text can be loaded into an array +in this way. If you want to change the contents of the array you should use +the function strcpy. +

+ + +

+

Two dimensional char arrays.

+ +Two dimensional arrays are a different kettle of fish! We can follow the +rules above to define the array like this. +
+	main()
+	{
+	  char Colours[3][6]={"red","green","blue"};
+
+	  printf ("%c \n", Colours[0][0]); 	/* O/P 'r' */
+	  printf ("%s \n", Colours[1]);    	/* O/P 'green' */
+	}
+
+ +The example above has reserved 18 consecutive bytes and created three +pointers into them. +
+
+                  ---------------------
+                 |red  \0green\0blue \0|

+   Colours[0] ----       |      |

Assignment operators.

+
+
+ +C has the following assignement operators: +
+	=   +=   -=   *=   /=   %=   <<=   >>=   &=   ^=   |=
+
+= is the obvious one. It takes the result of the expression on the right +and assigns it to the variable on the left (lvalue). +
+	main ()
+        {
+	  int a, b=4, c=10;
+	  a = b + c;
+	}
+
+I know this is stating the obvious, but: +
    +
  1. b is assigned the value 4 +
  2. c is assigned the value 10 +
  3. a is assigned the result of b plus C (14). +
+ +
+All the other operators act in a simular way. If you find yourself +coding the example on the left, it could be changed to the example on +the right. +
+	main ()				main()
+	{				{
+	  int a=4;			  int a=4;
+	  a = a * 4;			  a *= 4;
+	}				}
+
+The rule is as follows: +

+The lvalue is multiplied by the rvalue and the result assigned to the +lvalue. +

+Here is another example. +

+	main()				main()
+	{				{
+	    int a=10, b=2;	            int a=10, b=2;
+	    a /= b * 5;		            a = a / (b*5);
+	}				}
+
+Again both preduce the same answer (1). +

+

+ + +Increment (++) and Decrement (--)

To cast, casting

+
+
+ +If you want to change the +datatype of a variable +you have to use a technic called cast. For example if want to +change an int to a +float +you could use the following syntax: +

+

+ + + + +
+
+        
+    main()
+    {
+        int var1;
+        float var2;
+
+        var2 = (float)var1;
+    }
+
+
+
+

+As it happens this example would never be used in practice because C +would perform the conversion automatically. + +What this example does show is the cast operator () . This states, +the result of the expression (in this case var1) is to be a +data type of float. +

+

Constants

+
+Be sure you understand the difference between a 'constant' and a +declaration. +A constant has a value that cannot be changed. For example: +
+
+	1234
+	'x'
+	9.89
+	"String"
+
+
+Constants are used to assign a value to a variable. E.G +
+	int i;		/* declare a variable called 'i'	*/
+	i=1234;		/* assign the constant value 1234 to 
+			 * the variable 'i'			*/
+        i++;		/* Change the value of the variable.	*/
+
+ +
+

Integer constants.

+Interger constants can be expressed in the following ways. +
+	1234	(decimal)
+	0xff	(Hexidecimal)
+	0100	(Octal)
+	'\xf'	(Hex character)
+
+Examples of their use are: +
+	int i=255;	/* i assigned the decimal value of 255	*/
+
+	i-=0xff		/* subtract 255 from i			*/
+
+	i+=010		/* Add Octal 10 (decimal 8)		*/
+
+			/* Print 15 - there are easier ways...	*/
+	printf ("%i \n", '\xf'); 
+
+
+Integer constants are assumed to have a datatype of + int, if it will not fit into an 'int' +the compiler will assume the constant is a +long. You may also force the +compiler to use 'long' by putting an 'L' on the end of the +integer constant. +
+        1234L           /* Long int constant (4 bytes)          */
+
+The other modifier is 'U' for Unsigned. +
+        1234U           /* Unsigned int                         */
+
+and to complete the picture you can specify 'UL' +
+        1234UL          /* Unsigned long int                    */
+
+ +
+

Floating point constants.

+Floating point constants contain a decimal point or exponent. By default +they are double. +
+	123.4
+	1e-2
+

+

+
+

Chararacter constants.

+Are actually integers. +
+	'x'
+	'\000'
+	'\xhh'
+
+	escape sequences
+
+
+ +
+ +

String constants.

+ +Strings do not have a datatype of their own. +They are actually a sequence of char items terminated with a +\0. A string can be accessed with a +char pointer. +

+An example of a string would be: +

+
+	char *Str = "String Constant";

C Data types.

+
+
+

+ +

Variable definition

+C has a concept of 'data types' which are used to +define a variable +before its use.

+The definition of a variable will assign storage for the variable and +define the type of data that will be held in the location.

+So what data types are available? +

+ + +
int +float +double +char +void +enum +
+

+Please note that there is not a boolean data type. C does not have the +traditional view about logical comparison, but thats another story.

+ +Recent C++ compilers do have a boolean datatype. +

+ +

+

int - data type

+int is used to define integer numbers. +

+

+ +
+
+
+    {
+        int Count;
+        Count = 5;
+    }
+
+
+
+

+

+

float - data type

+float is used to define floating point numbers. +

+

+ +
+
+
+    {
+        float Miles;
+        Miles = 5.6;
+    }
+
+
+
+

+

+

double - data type

+double is used to define BIG floating point numbers. It reserves twice +the storage for the number. On PCs this is likely to be 8 bytes. +

+

+ +
+
+
+    {
+        double Atoms;
+        Atoms = 2500000;
+    }
+
+
+
+

+

+

char - data type

+char defines characters. +

+

+ +
+
+
+    {
+        char Letter;
+        Letter = 'x';
+    }
+
+
+
+

+ +

+

Modifiers

+The three data types above have the following modifiers. +

+

    +
  • short +
  • long +
  • signed +
  • unsigned +
+ +The modifiers define the amount of storage allocated to the variable. +The amount of storage allocated is not cast in stone. ANSI has the +following rules:

+

+

+ +
+
+
+        short int <=    int <= long int
+            float <= double <= long double
+
+
+
+

+What this means is that a 'short int' should assign less than or the same +amount of storage as an 'int' and the 'int' should be less or the same bytes +than a 'long int'. What this means in the real world is: +

+ + +
+
+
+                 Type  Bytes  Bits                Range
+
+
+
+
+            short int    2      16          -16,384 -> +16,383          (16kb)
+   unsigned short int    2      16                0 -> +32,767          (32Kb)
+         unsigned int    4      16                0 -> +4,294,967,295   ( 4Gb)
+                  int    4      32   -2,147,483,648 -> +2,147,483,647   ( 2Gb)
+             long int    4      32   -2,147,483,648 -> +2,147,483,647   ( 2Gb)
+          signed char    1       8             -128 -> +127
+        unsigned char    1       8                0 -> +255
+                float    4      32
+               double    8      64
+          long double   12      96
+
+
+

+These figures only apply to todays generation of PCs. Mainframes and +midrange machines could use different figures, but would still comply +with the rule above.

+You can find out how much storage is allocated to a data type by using +the sizeof operator. + +

+

Qualifiers

+

+

 + +The const qualifier is used to tell C that the variable value can not +change after initialisation.

+ + const float pi=3.14159; + +

+pi cannot be changed at a later time within the program.

+Another way to define constants is with the +#define preprocessor which +has the advantage that it does not use any storage (but who counts bytes + these days?).

C Operators/Expressions

+ +Operators are used with +operands +to build expressions. For example the +following is an expression containing two operands and one oprator. + +

+        4 + 5
+
+ +The following list of operators is probably not complete but does highlight +the common +operators and a few of the outrageous ones.... +

+C contains the following operator groups. +

+The order (precedence) that operators are evaluated can be seen +here. + +

+        --      Decrement (post and pre)
+        ++      Increment (post and pre)
+
+

Assignment

+These all perform an arithmetic operation on the lvalue and assign the +result to the lvalue. So what does this mean in English? Here is an example: +
   counter = counter + 1;
+can be reduced to +
   counter += 1;
+Here is the full set. +
+        =

+        +=      add.
+        -=      Subtract.
+        <<=     left shift.
+        >>=     Right shift.
+        &=      Bitwise AND.
+        ^=      bitwise exclusive OR (XOR).
+        |=      bitwise inclusive OR.
+

Increment and decrement.

+
+
+ +The traditional method of incrementing numbers is by coding something like: +
+	a = a + 1;
+
+Within C, this syntax is valid but you can also use the ++ operator to perform +the same function. +
+	a++;
+
+will also add 1 to the value of a. +By using a simular syntax you can also decrement a variable as shown below. +
+	a--;
+
+These operators can be placed as a prefix or post fix as below: +
+	a++;		++a;
+
+When used on their own (as above) the prefix and postfix have the same effect +BUT within an expression there is a subtle difference....

+ +

    +
  1. Prefix notation will increment the variable BEFORE the +expression is evaluated. +
  2. Postfix notation will increment AFTER the expression evaluation. +
+ +Here is an example: +
+	main()				main()
+	{				{
+	  int a=1;			  int a=1;
+	  printf(" a is %d", ++a);	  printf(" a is %d", a++);
+        }				}
+
+
+ +In both examples, the final value of a will be 2. BUT the first +example will print 2 and the second will print 1. + +
+ + Example program.

Pointers.

+
+

+Pointers are at the heart of C. When you crack this subject, you have got the worst +of C behind you. Before you tackle pointers though, you should get a grip +on arrays.

+

+ + + +
+

First Principles.

+To understand pointers, it may be worth understanding how normal +variables are stored. If you disagree, Click here +to move on. +

+What does the following program realy mean? +

+ + + + +
+
+
+        main()
+	{
+  	    int Length;     
+	}      
+
+
+

+In my mind, it means, reserve enough storage to hold an integer and assign the variable +name 'Length' to it. The data held in this storage is undefined. +Graphically it looks like: +

+
+      (Address) (Data)
+           ---- ----
+          | F1 |   <------- Length
+          |----|----|
+          | F2 |    |       
+          |----|----|
+          | F3 |    |
+          |----|----|
+          | F4 |    |
+           ---------    
+
+
+To put a known value into 'Length' we code, +

+ + + + +
+
+
+	main()
+	{
+	    int Length;
+  	    Length = 20;
+        }
+
+
+

+the deciamal value 20 (Hex 14) is placed into the storage location. +

+
+      (Address) (Data)
+	   ---- ----
+          | F1 | 00 <------- Length
+          |----|----|
+          | F2 | 00 |
+          |----|----|
+          | F3 | 00 |
+          |----|----|
+          | F4 | 14 |
+           ---------
+     
+
+Finally, if the program is expanded to become +

+ + + + +
+
+
+      main()
+      {
+          int Length;
+
+          Length = 20;
+
+          printf("Length is %d\n", Length);
+          printf("Address of Length is %p\n", &Length);
+      }
+      
+
+
+

+The output would look something like this ..... +

+    
+      Length is 20
+      Address of Length is 0xF1
+      
+
+ +Please note the '&Length' on the second printf statement. +The & means address of Length. +If you are happy with this, you should push onto the pointers below. +

+ +

+

Pointer definition.

+ +A pointer contains an address that points + +to data. +

+An example of code defining a pointer could be... +

+ + + + +
+
+
+      main()
+      {
+          int *Width;
+      }
+
+
+
+

+A graphical representation could be... +

+
+      (Address) (Data)
+           ---- ----
+          | F1 |    <------- Width
+          |----|----|
+          | F2 |    |
+          |----|----|
+          | F3 |    |
+          |----|----|
+          | F4 |    |
+           ---------
+		   
+
+So far, this variable looks the same as above, + the value stored at 'Width' is unknown. +To place a value in 'Width' you could code. +

+ + + + +
+
+
+      main()
+      {
+          int *Width;                                 /* 1 */
+
+          Width = (int *)malloc(sizeof(int));         /* 2 */
+
+          *Width = 34;                                /* 3 */
+      }
+
+
+
+

+
+      (Address) (Data)
+           ---- ----    
+          | F1 | 00 <------- Width   
+	  |----|----|               (Data) (Adress)
+          | F2 | 00 |                 ---------
+	  |----|----|         -------> 00 | D1 |
+	  | F3 | 00 |        |       |----|----|
+	  |----|----|  *Width|       | 00 | D2 |
+	  | F4 | D1 | -------        |----|----|
+	   ---------                 | 00 | D3 |
+	                             |----|----|
+				     | 22 | D4 |
+				      ---------
+		 
+
+ +Statements 2 and 3 are important here: +

+2) The malloc function reserves some storage and puts the address of the +storage into Width. +

+3) *Width puts a value into the storage pointed to by Width. +

+ +Unlike the +Length = 20 example above, the storage pointed to by 'Width' +does NOT contain 34 (22 in Hex), it contains the address where the value +34 can be found. +The final program is... +

+ + + + +
+
+
+      main()
+      {
+          int *Width;                               
+
+          Width  = (int *)malloc(sizeof(int));      
+	  *Width = 34;
+
+	  printf("  Data stored at *Width is %d\n", *Width); 
+	  printf("       Address of Width is %p\n", &Width);
+	  printf("Address stored at Width is %p\n",  Width);
+      }
+				  
+
+
+

+The program would O/P something like. +

+ + + + +
+
+
+          Data stored at *Width is 34
+	       Address of Width is 0xF1
+	Address stored at Width is 0xD1
+
+
+
+ +

+A pointer can point to any data type, ie +int, +float, +char. +When defining a pointer you +place an * (asterisk) character +between the data type and the variable name, here are a few examples. +

+ +
+
+
+	main()
+	{
+	    int    count;		/* an integer variable              */
+	    int   *pcount;		/* a pointer to an integer variable */
+	    float  miles;		/* a floating point variable.	    */
+	    float *m;			/* a pointer			    */
+	    char   ans;			/* character variable		    */ 	
+	    char  *charpointer;		/* pointer to a character variable  */
+	}
+
+
+
+

+ + +

+ + +

+

Pointers to arrays

+When looking at +arrays we had a program that accessed data within a +two dimensional character array. This is what the code looked like. + +
+        main()
+        {
+          char colours[3][6]={"red","green","blue"};
+        }
+
+The code above has defined an array of 3 elements, each pointing to 6 +character strings. +You can also code it like this. Which is actually more descriptive +because it indicates what is actually going on in storage. +
+        main()
+        {
+          char *colours[]={"red","green","blue"};
+        }
+
+ +Graphically it looks like this: +

+ +
+
+
+
+
+                        
+     colours  *colours *(colours+2) **colours
+          |         |       |           |
+          |         |       |           |
+          V         V       V           |     
+         ---       -----------          |     
+        |   |---->|   |   |   |         |     
+         ---       -----------          |     
+                    |   |   |           V     
+                    |   |   |         -----------------------
+                     --------------->| r | e | d |   |   |   |
+                        |   |         -----------------------
+                        |   |      
+                        |   |          -----------------------
+                         ---|-------->| g | r | e | e | n |   |
+                            |          -----------------------
+                            |
+                            |          -----------------------
+                             -------->| b | l | u | e |   |   |
+                                       -----------------------
+		            	        A           A
+                                        |           |
+                                        |           |
+                                **(colours+2)   *(*(colours+2)+3)
+                                 
+
+
+

+

+	printf("%s \n", colours[1]);
+	printf("%s \n", *(colours+1))
+
+will both return green. +

+ + +

+

Char Arrays verses Char pointers

+ +What is the difference +between these two lumps of code? +

+ +
+
+	
+  main()			
+  {			
+      char colour[]="red";		
+      printf("%s \n",colour);	
+  }				
+
+
+		 +
+
+  main()
+  {				
+      char *colour="red";
+      printf("%s \n",colour);	
+  }				
+
+
+
+

+The answer is, NOTHING! They both print the word +red because in both cases 'printf' is being passed a pointer to a +string. +

+An array of 4 bytes is +reserved and the text 'red' placed +into the storage array. The contents of the array can be chaged later +BUT on the left, the size of the array is fixed. +

+Here is a picture of the example on the right. The 'r' of 'red' is stored +at address 10, the 'e' is at address 11 etc. + +

+ +

+At this point it maybe worth looking at +the malloc function. + +

+ +

+

Void Pointers

+ +There are times when you write a function but do not know the datatype +of the returned value. When this is the case, you can use a void pointer. +

+ + + + + +
+
+
+  	int func(void *Ptr);
+
+  	main()
+  	{
+            char *Str = "abc";
+
+            func(Str);
+  	}
+
+  	int func(void *Ptr)
+  	{
+  	    printf("%s\n", Ptr);
+  	}
+
+
+

+ +Please note, you cant do pointer arithmatic on void pointers. +

+ + +

+

Pointers to pointers

+ +So far we have looked at pointers to data, but there is no reason why +we should not define a pointer to a pointer. The syntax looks like this. +

+ + + + + +
+
+
+	main()
+	{
+	    char **DoublePtr;
+	}
+
+
+

+ +A common use for these is when you want to return a +pointer in a function parameter. +

+ + + + + +
+
+   	#include 		/* malloc */
+
+	void Func(char **DoublePtr);
+
+	main()
+	{
+            char *Ptr;
+
+	    Func(&Ptr);
+	}
+
+	void Func(char **DoublePtr)
+	{
+	    *DoublePtr = malloc(50);
+	}
+
+
+

+ +

+ +

+ +

Pointers to functions

+ +Pointers to functions can be used to create 'callback' functions. +An example of these pointers can be seen in the +qsort function. +

+

Examples.

+ + +Simple example passing a function pointer.

+ + + Example passing 'int' variables.

+ + + Example passing 'char' and 'char *' variables.

+

Remote Procedure Calls (RPC).

+
+In the normal scope of things, a program can only call a function +that is linked into the executable or provided by a shared library. +RPC allows programs to execute functions in another executing program, cool! +

+RPC has a concept of clients and servers. +

    +
  1. The client issues requests to the server. +
  2. Servers perform the requests and return the results. +
  3. The data that flows between client and server includes +int, float, strings and structures. +
  4. The client and server can be on the same host or different hosts +connected via a network. +
  5. The hosts do not have to be the same artitechture. +
+ +The RPC API has three levels of support. +By using the highest level +RPC is responcable for most of the code but is not too flexable. The lowest +level requres more coding but gives the programmer more control over how RPC +functions. +

+The easiest way to start with RPC is to use a program called rpcgen +this reads a file that describes the required interface between client and server +and generates C code that you can include in your client and server. + +

+
+	prog.x --> rpcgen ---> prog.h        Header file
+                          ---> prog_clnt.c   Client stubs file
+                          ---> prog_svc.c    Server stubs file
+                          ---> prog_xdr.c    XDR routines (more later).
+
+
+You write prog.x and rpcgen generates +prog.h prog_clnt.c prog_svc.c prog_xdr.c + +You then write the client and server and link them with the rpcgen code +to complete the RPC system. + +
+
+	client.c    -----> client executable
+        prog.h      ---|
+        prog_clnt.c ---|
+        prog_xdr.c  ---|
+
+        server.c    -----> Server executable
+        prog.h      ---|
+        prog_svc.c  ---|
+        prog_xdr.c  ---|
+
+
+
+ +Ok, time for some examples. + +

Calling an RPC server function without passing any arguments.

+This is the simplest form of RPC. + +

+

+ + + + + +
+void.x +
+
+
+  /* RPCGEN code decribing the client/server API. */
+ 
+  program MJLPROG
+  {
+    version MJLVERS
+    {
+      void VOID(void) = 1;
+    
+    } = 1;
+  } = 0x20000001;
+
+
+
+

+ +void.x describes the RPC interface between the client +and server. There are some important items to note here. +

+ + + + + + + + + + + + +
+
+program MJLPROG
+{
+} = 0x20000001;
+

C Storage Classes.

+
+
+

+C has a concept of 'Storage classes' which are used to define the +scope (visability) and life time of variables and/or functions. +

+So what Storage Classes are available? +

+ + + +
auto +register +static +extern +typedef +
+

+

+

auto - storage class

+auto is the default storage class for local variables. +
+	{
+	    int Count;
+	    auto int Month;
+	}
+
+ +The example above defines two variables with the same storage class. +auto can only be used within functions, i.e. local variables.

+

+

register - Storage Class

+register is used to define local variables that should be stored +in a register instead of RAM. This means that the variable has a maximum size +equal to the register size (usually one word) and cant have the unary '&' +operator applied to it (as it does not have a memory location). +
+	{
+	  register int  Miles;
+	}
+
+Register should only be used for variables that require quick access - such +as counters. It should also be noted that defining 'register' goes not mean +that the variable will be stored in a register. It means that it MIGHT be stored +in a register - depending on hardware and implimentation restrictions.

+

+

static - Storage Class

+ +Click here for static functions +

+static is the default storage class for +global variables. The two +variables below (count and road) both have a static storage class. +

+

+ + + + +
+
+
+     static int Count;
+     int Road;
+
+     main()
+     {
+       printf("%d\n", Count);
+       printf("%d\n", Road);
+     }
+
+
+
+

+ +'static' can also be defined within a function. If this is done, the variable +is initalised at compilation time and retains its value between calls. +Because it is initialsed at compilation time, the initalistation value +must be a constant. +This is serious stuff - tread with care. +

+

+ + + + +
+
+
+     void Func(void)
+     {
+       static Count=1;
+     }
+
+
+
+

+Here is an example

+ + +There is one very important use for 'static'. Consider this bit of code. +

+

+ + + + +
+
+
+     char *Func(void);
+
+     main()
+     {
+       char *Text1;
+       Text1 = Func();
+     }
+
+     char *Func(void)
+     {
+       char Text2[10]="martin";
+       return(Text2);
+     }
+
+
+
+

+'Func' returns a pointer to the memory location where 'Text2' starts +BUT Text2 has a storage class of auto and will disappear +when we exit the function and could be overwritten by something else. The +answer is to specify: +

+

+ + + + +
+
+
+     static char Text[10]="martin";
+
+
+
+

+The storage assigned to 'Text2' will remain reserved for the duration if the +program. + +

+

extern - storage Class

+extern defines a global variable that is visable to ALL object +modules. When you use 'extern' the variable cannot be initalized as +all it does is point the variable name at a storage location that has +been previously defined. +
+
+
+ 	Source 1				Source 2
+        --------				--------
+
+
+	extern int count;			int count=5;
+
+        write()					main()
+        {					{
+          printf("count is %d\n", count);	  write();
+        }					}
+
+ +Count in 'source 1' will have a value of 5. If source 1 changes the +value of count - source 2 will see the new value. Here are some example +source files. +

+Source 1
+Source 2

+ +The compile command will look something like.

+

+	gcc source1.c source2.c -o program
+
+ +

Strings.

+
+

+

Pointers to strings.

+ +C does not have a "string" datatype. +To create a string you have to use a char array +or a char pointer. +If you are not familur with char arrays +I recomend that you read about them now. +

+To recap, a char pointer is +defined like this: +

+ + +
+
+ 
+     main()
+     {
+       char *Text;
+     }
+     
+
+
+

+ +All this program does is reserve storage that will hold an address. +At this point the address could be anything. To initalize Text +you can code: +

+ +
+
+    
+     main()
+     {
+       char *Text = "Thunder";
+     }
+     
+
+ + +Text now has the address of the first character in Thunder. +Graphically, things look like this. + +

+
+      (Address) (Data)
+      
+           ---- ----    
+          | F1 | 00 <------- Text

+                                     | 65 (e) | D6 |
+                                     |--------|----|
+                                     | 72 (r) | D7 |
+                                     |--------|----|     
+                                     | 00     | D8 |
+                                      -------------
+
+
+

+ +Please note the 00 at the end of Thunder. This is +the NULL character and is used to mark the +end of a string. +

+If we wanted to O/P the data pointed to by a char pointer + we can code. +

+ + +
+Source +
+
+
+     main()
+     {
+       char *Text1 = "Thunder";          /* Define and initalize */
+       char *Text2;                      /* Define only          */
+       
+       Text2 = "Bird";                   /* Point to some text   */
+       
+       printf("%s%s\n", Text1, Text2);
+     }
+     
+
+
+Result +
+
+
+      ThunderBird
+
+
+
+

+ +This is all very well, but there is a MAJOR problem! Thunder +and Bird are +constants, they cannot be +changed in anyway. +We need a method of pointing to some storage that can be altered +and true to form, C provides a function called +malloc to do just that. +

True or False.

+
+
+The concept of an expression evaluating to true or false is one of +the corner stones of C. BUT the language derives true and false in an +unusual way.

+Basicly there is no boolean value. The number 0 is considered to be false +and all other numbers are considered to be true....

+ +Please consider the following expressions. + +

+	(1 == 1) 	true
+	(1 != 1)	false
+	(i  = 1)   	true
+	(i  = 0)   	false
+	(i  = 1 + 1) 	true
+
+The first two examples should be clear but the last ones need explanation .

+The last three examples assign a value to a variable and a side effect of +assignment is to return the value assigned, it is this value that is tested +to be true or false.

+Looking at the last example: +

+	(i = 1 + 1)
+  	(i = 2)
+	(2)
+
+ +
    +
  • The third expression assigns a value of 1 to i. 1 is considered to +be true because it is non-zero. +

    +

  • The fourth expression assigns a value of 0 to i. 0 is considered to +be false. +

    +

  • The fith expression assigns a value of 2 to i. 2 is considered to +be true, because it is non-zero. +

Data type conversion

+
+ +An operator must have +operands +of the same +type before it can carry out the operation. Because of this, C will perform +some automatic conversion of data types. +

+These are the general rules for binary operators (* + / % etc): +

+

    +
  • If either operand is long double the other is converted to +long double. +

    +

  • Otherwise, if either operand is double the other is converted +to double +

    +

  • Otherwise, if either operand is float the other is converted +to float +

    +

  • Otherwise, convert char and short to int +

    +

  • Then, if an operand is long convert the other to long. +

'C' is a Language specifically +created +in order to allow the programmer access to almost all of the machine's +internals +- registers, I/O slots and absolute addresses. However, at the same time, +'C' allows for as much data hiding and programme text modularisation as is +needed to allow very complex multi-programmer projects to be constructed in an +organised and timely fashion. During the early 1960s computer Operating Systems +started to become very much more complex with the introduction of +multi-terminal +and multi-process capabilities. Prior to this time Operating Systems had been +carefully and laboriously crafted using assembler codes, and many programming +teams realised that in order to have a working o/s in anything like a +reasonable time this was now longer economically feasible. This then was the +motivation to produce the 'C' Language, which was first implemented in +assembler on a Digital Equipment Corporation PDP-7. Of course once a simple +assembler version was working it was possible to rewrite the compiler in 'C' +itself. This was done in short order and therefore as soon as the PDP-11 was +introduced by DEC it was only necessary to change the code generator section +of the compiler and the new machine had a compiler in just a few weeks. 'C' was +then used to implement the UNIX o/s. This means, that a complete UNIX can be +transported, or to use the simple jargon of today; 'ported to a new machine in +literally just a few months by a small team of competent programmers. + +Enough of the past. Lets see the various actions, or compilation phases through +which the `C' compilation system has to go in order that your file of `C' +program text can be converted working program. + +Assuming that you are able to work an editor and can enter a script and create +a file. Please enter the following tiny program. + +#ident "@(#) Hello World - my first program" + +#include + +char *format = "%s", + *hello = "Hello World...\n"; + +main() +{ + printf ( format, hello ); + } + +Now save it in a file called hello.c. Lower case is allowed - encouraged, no +less - under the UNIX operating system. + +Now type: + +cc -o hello hello.c + +The computer will apparently pause for a few moments and then the +Shell, or Command Line Interpreter prompt will re-appear. + +Now type: + +hello + +Lo and behold the computer will print + +Hello World... + +Let's just look at what the computer did during the little pause. + +The first action is to activate a preliminary process called the pre-processor. +In the case of hello.c all it does is to replace the line + +#include + +with the file stdio.h from the include files library. The file stdio.h provides +us with a convenient way of telling the compiler that all the i/o functions +exist. There are a few other little things in stdio.h but they need not +concern us at this stage. + +In order to see what the pre-processor actually outputs, you might like to +issue the command: + +cc -P hello.c + +The 'cc' command will activate the 'C' compilation system and the -P option +will stop the compilation process after the pre-processing stage, and another +file will have appeared in your directory. Have a look, find hello.i and use +the editor in view mode to have a look at it. So issue the command: + +view hello.i + +You will see that a number of lines of text have been added at the front of the +hello.c program. What's all this stuff? Well, have a look in the file called +/usr/include/stdio.h again using the view command. + +view /usr/include/stdio.h + +Look familiar? + +Now the next stage of getting from your program text to an executing program is +the compilation of your text into an assembler code program. After all that is +what a compiler is for - to turn a high level language script into a program. +Lets see what happens by issuing the command + +cc -S hello.c + +Once again there is another file in your directory - this time with a .s +suffix. + +Lets have a look at it in the same way as the .i file + +view hello.s + +You will doubtless notice a few recognizable symbols and what appears to be a +pile of gibberish. The gibberish is in fact the nmemonics for the machine +instructions which are going to make the computer do what you have programmed +it to do. + +Now this assembler code has to be turned into machine instructions. +To do this issue the command. + +cc -g -c hello.s + +Now, yet again there is another file in your directory - this time the suffix +is ".o". This file is called the object file. It contains the machine +instructions corresponding exactly to the nmemonic codes in the .s file. +If you wish you can look at these machine codes using one of the commands +available to examine object files. + +dis -L -t .data hello.o >hello.dis + +The output from these commands won't be very meaningful to you at this stage, +the purpose of asking you to use them is merely to register in your mind the +fact that an object file is created as a result of the assembly process. + +The next stage in the compilation process is called by a variety of names - +"loading", "linking", "link editing". What happens is that the machine +instructions in the object file ( .o ) are joined to many more instructions +selected from an enormous collection of functions in a library. This phase of +the compilation process is invoked by the command:- + +cc -o hello hello.o + +Now, at last, you have a program to execute! So make it do it's thing by +putting the name of the executable file as a response to the Shell or Command +Line Interpreter prompt. + +hello + +Presto, the output from your program appears on the screen. + +Hello World... + +You are now allowed to rejoice and have a nice warm fuzzy to hold! +You have successfully entered a `C' program, compiled it, linked it, and +finally, executed it! + +Having gone through all the various stages of editing, pre-processing, +compiling, assembling, linking, and finally executing, by hand as it were, you +can now rest assured that all the stages are automated by the 'cc' command, and +you can forget how to invoke them! Just remember that the computer has to do +them in order for you to have a program to execute. + +The single command you use to activate the C Compiler is: + +cc -o hello hello.c + +The word after the -o option is the name of the executable file, if you don't +provide a name here the compiler dreams up the name "a.out". The source file +MUST have the .c extension otherwise the compiler complains and stops working. + +Notes: + + The command names used in the above text are those of standard UNIX, + Your particular system may well use a different name for the 'C' compiler. + bcc - for Borland 'C'. + gcc - GNU 'C', which is standard on the Linux operating system. + lc - Lattice 'C', available on IBM and clone P.C.s as well as the Amiga. + Check in the Documentation which came with your compiler. + The same notions apply to the text editor. + +Differences between 'C' and other languages. + +In the years since 'C' was developed it has changed remarkable little. +This fact is a bouquet to the authors, who had the vision and understanding to +create a language which has endured so well. The strengths and weaknesses +should be pointed out here. + +The big plus is that it is possible to do everything ( well at least 99.9% ) in +'C' while other languages compel you to write a procedure, subroutine or +function in assembler code. + +'C' has very good facilities for creating tables of constant data within the +source file. + +'C' doesn't do very much to protect you from yourself. This means that the +resulting code executes faster than most other high level languages, but a much +greater degree of both care and understanding is demanded from the programmer. + +'C' is not a closely typed language, although the newer compilers are offering +type checking as part of the language itself as opposed to having to use a +separate program for mechanised debugging. + +'C' is a small language with very few intrinsic operations. +All the heavy work is done by explicit library function calls. + +'C' allows you to directly and conveniently access most of the internals of +the machine ( the memory, input output slots, and CPU registers ) from the +language without having to resort to assembler code. + +'C' compilers have an optimisation phase which can be invoked if desired. +The output code can be optimised for either speed or memory usage. The code +will be just as good as that produced by an assembly code programmer of normal +skill - real guru programmers can do only slightly better. + +Copyright notice:- + +(c) 1993 Christopher Sawtell. + +I assert the right to be known as the author, and owner of the +intellectual property rights of all the files in this material, +except for the quoted examples which have their individual +copyright notices.

The information may be either program instructions or +data elements. The latter are further subdivided into several different types, +and stored in the computer's memory in different places as directed by the +storage class used when the datum element is defined. + +These types are: + + a) The Character. + + This is a group of 8 data bits and in 'C' represents either + a letter of the Roman alphabet, or a small integer in the range of 0 + through to +255. So to arrange for the compiler to give you a named + memory area in which to place a single letter you would "say": + + char letter; + + at the beginning of a program block. You should be aware that + whether or not a char is signed or unsigned is dependant + on the design of the processor underlying your compiler. + In particular, note that both the PDP-11, and VAX-11 made by + Digital Equipment Corporation have automatic sign extention of +char. + This means that the range of char is from -128 through to +127 + on these machines. Consult your hardware manual, there may be + other exceptions to the trend towards unsigned char as the +default. + + This test program should clear things up for you. + +/* ----------------------------------------- */ + +#ident "@(#) - Test char signed / unsigned."; + +#include + +main() +{ + char a; + unsigned char b; + + a = b = 128; + a >>= 1; + b >>= 1; + printf ( "\nYour computer has %ssigned char.\n\n", a == b ? "un" : "" ); + } + +/* ----------------------------------------- */ + + Here ( Surprise! Surprise! ) is its output on a machine which has + unsigned chars. + +Your computer has unsigned char. + + Cut this program out of the news file. Compile and execute it on + your computer in order to find out if you have signed or +unsigned char. + + b) The Integers. + + As you might imagine this is the storage type in which to store whole + numbers. There are two sizes of integer which are known as short and long. + The actual number of bits used in both of these types is Implementation + Dependent. This is the way the jargonauts say that it varies from computer + to computer. Almost all machines with a word size larger than sixteen bits + have the the long int fitting exactly into a machine word and +a short int + represented by the contents of half a word. It's done this way because + most machines have instructions which will perform arithmetic +efficiently + on both the complete machine word as well as the half-word. +For the + sixteen bit machines, the long integer is two machine words +long, + and the short integer is one. + + short int smaller_number; + long int big_number; + + Either of the words short or long may be omitted as a default is + provided by the compiler. Check your compiler's documentation +to see + which default you have been given. Also you should be aware +that some + compilers allow the you to arrange for the integers declared +with just + the word "int" to be either short or long. The range for a +short int on + a small computer is -32768 through to +32767, and for a long +int + -4294967296 through to +4294967295. + + c) The Real Numbers. + + Sometimes known as floating point numbers this number representation + allows us to store values such as 3.141593, or -56743.098. So, using + possible examples from a ship design program you declare floats and + doubles like this: + + float length_of_water_line; /* in meters */ + double displacement; /* in grammes */ + + In the same way that the integer type offers two sizes so does the + floating point representation. They are called float and double. Taking + the values from the file /usr/include/values.h the ranges which can be + represented by float and double are: + + MAXFLOAT 3.40282346638528860e+38 + MINFLOAT 1.40129846432481707e-45 + MAXDOUBLE 1.79769313486231470e+308 + MINDOUBLE 4.94065645841246544e-324 + + However you should note that for practical purposes the maximum + number of significant digits that can be represented by a +float + is approximately six and that by a double is twelve. Also you +should + be aware that the above numbers are as defined by the IEEE +floating + point standard and that some older machines and compilers do +not + conform. All small machines bought retail will conform. If you +are + in doubt I suggest that refer to your machine's documentation +for + the whole and exact story! + + + d) Signed and unsigned prefixes. + + For both the character and integer types the declaration can be + preceded by the word "unsigned". This shifts the range so that +0 + is the minimum, and the maximum is twice that of the signed +data + type in question. It's useful if you know that it is +impossible + for the number to go negative. Also if the word in memory is +going + to be used as a bit pattern or a mask and not a number the use +of + unsigned is strongly urged. If it is possible for the sign bit +in + the bit pattern to be set and the program calls for the bit +pattern + to be shifted to the right, then you should be aware that the +sign + bit will be extended if the variable is not declared unsigned. + The default for the "int" types is always "signed", and, as +discussed + above that of the "char" is machine dependent. + + This completes the discussion on the allocation of data types, except to + say that we can, of course, allocate arrays of the simple types simply by + adding a pair of square brackets enclosing a number which is the size of + the array after the variable's name: + + char client_surname[31]; + + This declaration reserves storage for a string of 30 characters plus the + NULL character of value zero which terminates the string. + + Structures. + + Data elements which are logically connected, for example - to use the + example alluded to above - the dimensions and other details about a +sea + going ship, can be collected together as a single data unit called a + struct. One possible way of laying out the struct in the source code +is: + +struct ship /* The word "ship" is known as the structure's "tag". */ +{ + char name[30]; + double displacement; /* in grammes */ + float length_of_water_line; /* in meters */ + unsigned short int number_of_passengers; + unsigned short int number_of_crew; + }; + + Note very well that the above fragment of program text does NOT + allocate any storage, it merely provides a named template to +the + compiler so that it knows how much storage is needed for the + structure. The actual allocation of memory is done either like +this: + +struct ship cunarder; + + Or by putting the name of the struct variable between the "}" +and + the ";" on the last line of the definition. Personally I don't + use this method as I find that the letters of the name tend to +get + "lost" in the - shall we say - amorphous mass of characters +which + make up the definition itself. + + The individual members of the struct can have values assigned to + them in this fashion: + + cunarder.displacement = 97500000000.0; + cunarder.length_of_water_line = 750.0 + cunarder.number_of_passengers = 3575; + cunarder.number_of_crew = 4592; + + These are a couple of files called demo1.c & demo1a.c which contain + small 'C' programs for you to compile.

There is + just the little matter of the position in memory of the variables' + storage. + + 'C' has been designed to maximise the the use of memory by allowing you + to re-cycle it automatically when you have finished with it. + A variable defined in this way is known as an 'automatic' one. Although + this is the default behaviour you are allowed to put the word 'auto' in + front of the word which states the variable's type in the definition. + It is quite a good idea to use this so that you can remind yourself + that this variable is, in fact, an automatic one. There are three other + storage allocation methods, 'static' and 'register', and 'const'. + The 'static' method places the variable in main storage for the whole + of the time your program is executing. In other words it kills the + 're-cycling' mechanism. This also means that the value stored there + is also available all the time. The 'register' method is very machine + and implementation dependent, and also perhaps somewhat archaic in + that the optimiser phase of the compilation process does it all for + you. For the sake of completeness I'll explain. Computers have a small + number of places to store numbers which can be accessed very quickly. + These places are called the registers of the Central Processing Unit. + The 'register' variables are placed in these machine registers instead +of + stack or main memory. For program segments which are tiny loops the +speed + at which your program executes can be enhanced quite remarkably. + The optimiser compilation phase places as many of your variables into + registers as it can. However no machine can decide which of the +variables + should be placed in a register, and which may be left in memory, so if + your program has many variables and two or three should be register +ones + then you should specify which ones the compiler. + + All this is dealt with at much greater detail later in the course. + + Pointers. + + 'C' has the very useful ability to set up pointers. These are memory + cells which contain the address of a data element. The variable name is + preceeded by a '*' character. So, to reserve an element of type char +and + a pointer to an element of type char, one would say. + +char c; +char *ch_p; + + I always put the suffix '_p' on the end of all pointer variables + simply so that I can easily remember that they are in fact pointers. + + There is also the companion unary operator '&' which yields the + address of the variable. So to initialize our pointer ch_p to point + at the char c, we have to say. + + ch_p = &c; + + Note very well that the process of indirection can procede to any + desired depth, However it is difficult for the puny brain of a normal + human to conceptualize and remember more that three levels! So be +careful + to provide a very detailed and precise commentry in your program if + you put more than two or three stars. + + + Getting data in and out of your programs. + + As mentioned before 'C' is a small language and there are no intrinsic + operators to either convert between binary numbers and ascii + characters or to transfer information to and fro between the + computer's memory and the peripheral equipment, such as terminals or + disk stores. + + This is all done using the i/o functions declared in the file stdio.h + which you should have examined earlier. Right now we are going to look + at the functions "printf" and "scanf". These two functions together + with their derivatives, perform i/o to the stdin and stdout files, + i/o to nominated files, and internal format conversions. This means + the conversion of data from ascii character strings to binary numbers + and vice versa completely within the computer's memory. It's more + efficient to set up a line of print inside memory and then to send the + whole line to the printer, terminal, or whatever, instead of + "squirting" the letters out in dribs and drabs! + + Study of them will give you understanding of a very convenient way to + talk to the "outside world". + + So, remembering that one of the most important things you learn in + computing is "where to look it up", lets do just that. + If you are using a computer which has the unix operating system, + find your copy of the "Programmer Reference Manual" and turn to the + page printf(3S), alternatively, if your computer is using some other + operating system, then refer to the section of the documentation which + describes the functions in the program library. + + You will see something like this:- + + NAME + printf, fprintf, sprintf - print formatted +output. + + SYNOPSIS + #include + + int printf ( format [ , arg ] ... ) + char *format; + + int fprintf ( stream, format [ , arg ] ... ) + FILE *stream; + char *format; + + int sprintf ( s, format [ , arg ] ... ) + char *s, *format; + + DESCRIPTION + + etc... etc... + + The NAME section above is obvious isn't it? + + The SYNOPSIS starts with the line #include . This tells + you that you MUST put this #include line in your 'C' source code + before you mention any of the routines. The rest of the paragraph + tells you how to call the routines. The " [ , arg ] ... " heiroglyph + in effect says that you may have as many arguments here as you wish, + but that you need not have any at all. + + The DESCRIPTION explains how to use the functions. + + Important Point to Note: + + Far too many people ( including the author ) ignore the fact that + the printf family of functions return a useful number which can be + used to check that the conversion has been done correctly, and that + the i/o operation has been completed without error. + + Refer to the format string in the demonstration program above for + an example of a fairly sophisticated formatting string. + + In order to fix the concepts of printf in you mind, you + might care to write a program which prints some text in three ways: + +a) Justified to the left of the page. ( Normal printing. ) +b) Justified to the right of the page. +c) Centred exactly in the middle of the page. + + Suggestions and Hint. + + Set up a data area of text using the first verse of "Quangle" as data. + Here is the program fragment for the data:- + +/* ----------------------------------------- */ + +char *verse[] = +{ + "On top of the Crumpetty Tree", + "The Quangle Wangle sat,", + "But his face you could not see,", + "On account of his Beaver Hat.", + "For his Hat was a hundred and two feet wide.", + "With ribbons and bibbons on every side,", + "And bells, and buttons, and loops, and lace,", + "So that nobody ever could see the face", + "Of the Quangle Wangle Quee.", + NULL + }; + +/* ----------------------------------------- */ + + Cut it out of the news file and use it in a 'C' program file called + verse.c + + Now write a main() function which uses printf alone for (a) & (b) + You can use both printf() and sprintf() in order to create + a solution for (c) which makes a good use of the capabilities + of the printf family. The big hint is that the string controlling + the format of the printing can change dynamically as program execution + proceeds. A possible solution is presented in the file verse.c which is + appended here. I'd like to suggest that you have a good try at making + a program of you own before looking at my solution. + ( One of many I'm sure ) + +/* ----------------------------------------- */ + +#include + +char *verse[] = +{ + "On top of the Crumpetty Tree", + "The Quangle Wangle sat,", + "But his face you could not see,", + "On account of his Beaver Hat.", + "For his Hat was a hundred and two feet wide.", + "With ribbons and bibbons on every side,", + "And bells, and buttons, and loops, and lace,", + "So that nobody ever could see the face", + "Of the Quangle Wangle Quee.", + NULL + }; + +main() +{ + char **ch_pp; + + /* + ** This will print the data left justified. + */ + + for ( ch_pp = verse; *ch_pp; ch_pp++ ) printf ( "%s\n", *ch_pp ); + printf( "\n" ); + + /* + ** This will print the data right justified. + ** + ** ( As this will print a character in column 80 of + ** the terminal you should make sure any terminal setting + ** which automatically inserts a new line is turned off. ) + */ + + for ( ch_pp = verse; *ch_pp; ch_pp++ ) printf ( "%79s\n", *ch_pp ); + printf( "\n" ); + + /* + ** This will centre the data. + */ + + for ( ch_pp = verse; *ch_pp; ch_pp++ ) + { + int length; + char format[10]; + + length = 40 + strlen ( *ch_pp ) / 2; /* Calculate the +field length */ + sprintf ( format, "%%%ds\n", length ); /* Make a format +string. */ + printf ( format, *ch_pp ); /* Print line of +verse, using */ + } /* generated format +string */ + printf( "\n" ); + } + +/* ----------------------------------------- */ + + If you cheated and looked at my example before even attempting + to have a go, you must pay the penalty and explain fully why + there are THREE "%" signs in the line which starts with a call + to the sprintf function. It's a good idea to do this anyway! + + + So much for printf(). Lets examine it's functional opposite - scanf(), + + Scanf is the family of functions used to input from the outside world + and to perform internal format conversions from character strings to + binary numbers. Refer to the entry scanf(3S) in the Programmer + Reference Manual. ( Just a few pages further on from printf. ) + + The "Important Point to Note" for the scanf family is that the + arguments to the function are all POINTERS.

Have a go and write yourself a trivial little program, and have a + look at the compiler ouput code. Lesson 1 told you how! + + When using a pointer to reference a structure we have to use a "pointer + offset" operator in order to access the member of the struct we require: + + vessel_p = fleet; + + vessel_p->name = "Queen Mary"; + vessel_p->displacement = 97500000000.0; + vessel_p->length_of_water_line = 750.0 + vessel_p->number_of_passengers = 3575; + vessel_p->number_of_crew = 4592; + + Remember: + + It's a "." when accessing a struct which is in storage declared in + the program. + + It's a "->" when accessing a struct at which a pointer is pointing. + + Initialisation of arrays. + + 'C' has the facility to initialise variables in a program script. + + Some examples: + + char *qbf = "The quick brown fox jumped over the lazy dogs back"; + + int tic_tac_toe[3][3] = + { + { 1, 2, 3 }, + { 4, 5, 6 }, + { 7, 8, 9 } + }; + + struct ship fleet[2] = + { + { "Queen Elizabeth", 97500000000.0, 750.0, 3575, 4592 }, + { "Queen Mary", 115000000000.0, 875.0, 4500, 5500 } + }; + + Take a careful note of where the commas and semi-colons go ( and don't go )! + + Initialised Tables of Indeterminate Length. + + One nice feature 'C' offers is that it is able to calculate + the amount of storage required for a table by 'looking' at the number + of initialisers. + +char *verse[] = +{ + "On top of the Crumpetty Tree", + "The Quangle Wangle sat,", + "But his face you could not see,", + "On account of his Beaver Hat.", + "For his Hat was a hundred and two feet wide.", + "With ribbons and bibbons on every side,", + "And bells, and buttons, and loops, and lace,", + "So that nobody ever could see the face", + "Of the Quangle Wangle Quee." + NULL + }; + + Note the * character in the definition line. This means that we are going + to make an array of pointers to variables of type char. As there is no + number between the [ ] characters the compiler calculates it for us. + With this kind of set-up it is nice and easy to add extra information + to the table as program development proceeds. The compiler will calculate + the new dimension for you. The point to remember is that the program has to + know - from the contents of the table - that it has come to the end of the + table! So you have to make a special entry which CANNOT under any + circumstances be a real data element. We usually use NULL for this. + The other way is to calculate the size of the table by using the sizeof + operator - Note that although use of sizeof looks like a function call + it is in fact an intrinsic operator of the language. The result is + available at compile time. So one can say:- + + #define SIZE_OF_VERSE sizeof verse + + There is one final initialised data type, the enum. It is a fairly recent + addition to the language. + + enum spectrum { red, orange, yellow, green, blue, indigo, violet } colour; + + In this construct the first symbol is given the value of 0 and for each + following symbol the value is incremented.

Take care! In + practice there is little difference between the enum language construct + and a number of define statements except perhaps aesthetics.

'C' makes efficient use of this machine feature +by providing the above set of operations each of which translates directly +to its corresponding machine instruction.

The qsort algorithm is well documented elsewhere. + + There is just one more point to notice about using function libraries. +The 'C' compilation system will load functions from the library /lib/libc.a +as a default. All others have to be indicated to the linking loader by a +switch on the shell interactive command line. + +$ cc -o prog prog.c -L /usr/local/lib -lgdbm -lmalloc + + You might use this command line to compile and link a program which +uses both the GNU gdbm data-base manager library, which is installed in +the directory /usr/local/lib, and the enhanced malloc library. Now, there +hangs a tale! I remember having to compile a program suit off Usenet and +it just would not work properly. No error messages, no warnings, no +missing linking-loader symbols. It just "died" when I tried to run it. +After many, many hours of total frustration, I thought that I would try +linking in the enhanced malloc library. Presto! It worked. + + Note very well. + + A common misconception is the notion that having a #include +line in the source text will automagically tell the linking loader to +get the functions from the appropriate library. Remove this erroroneous +notion from your mind. It won't. The -lwhatever flag on the shell command +line which initiates execution of "cc" or "ld" is the only way to tell the +loader where to look for the required library. + + +-- + +----------------------------------------------------------------------+ + | NAME Christopher Sawtell | + | SMAIL 215 Ollivier's Road, Linwood, Christchurch, 8001.

Now this might seem to be stating the absolute obvious, and it +is but after looking at many programs it would seem that there is a very +definite need to say it. + + So how does one go about reducing the probability of making mistakes? + + There are many strategies, and over the years I have evolved my own set. + I have found that some of the most important are: + + 1) Document what you are going to do before yes BEFORE you write any code. + Set up the source files for the section of the program you are going to + write and put some lines of explanation as to what you intend to do in + this file. Be as precise as you can, but don't go into the detail of + explaining in English, or your First Language, exactly what every + statement does. + + 2) Make sure that you keep each file as small as is sensible. Some program + authors say that one should put only one function in a file. It's my + personal opinion that this is going a little bit over the top, but + certainly you should not have more than one logical activity in a source + file. It's easier to find a needle in a tiny haystack than in a big one! + + 3) Always use names for the objects in your program which are fully + descriptive, or at the very least are meaningful nmemonics. Put yourself + in the position of some poor soul who - a couple of years later, after you + have long finished with the project, and left the country - has been given + the task of adding a small feature to your exquisite program. Now in the + rush to get your masterpiece finished you decided to use variable names + like "a4" and "isb51" simply so that you can get the line typed a + fraction of a second faster than if you used something like + "customer_address[POST_CODE]" and "input_status_block[LOW_FUEL_TANK_#3]. + The difference in ease of understanding is obvious, isn't it? However + judging by some programs which I have seen published in both magazines and + in the public domain program sources, the point has still to be made. + + 4) ALWAYS take great care with the layout of your code. + It's my opinion that the opening brace of ALL program structures should + be on a new line. Also if you put them in the leftmost column for structs, + enums, and initialised tables, as well as functions, then the + 'find function' keystrokes ( "[[" and "]]" ) in vi will find them as well + as the functions themselves. Make sure you have the "showmatch" facility + in vi turned on. ( And watch the cursor jump when you enter the + right hand brace, bracket, or parenthesis. ) + + 5) Try as hard as you can to have as few global variables as possible. + Some people say never have any globals. This is perhaps a bit too + severe but global variables are a clearly documented source of + programming errors. If it's impossible to perform a logical activity + in an efficient way without having a global or two, then confine + the scope of the globals to just the one file by marking the defining + declaration "static". This stops the compiler producing a symbol which + the linking loader will make available to all the files in your source. + + 6) Never EVER put 'magic numbers' in you source code. Always define constants + in a header file with #define lines or enum statements. + + Here is an example:- + + +/* ----------------------------------------- */ + +#include + +enum status_input_names +{ + radiator_temperature, + oil_temperature, + fuel_pressure, + energy_output, + revolutions_per_minute + }; + +char *stats[] = +{ + "radiator_temperature", + "oil_temperature", + "fuel_pressure", + "energy_output", + "revolutions_per_minute" + }; + +#define NUMBER_OF_INPUTS ( sizeof ( stats ) / sizeof ( stats[0])) + +main() +{ + enum status_input_names name; + + printf ( "Number of Inputs is: %d\n", NUMBER_OF_INPUTS ); + for ( name = radiator_temperature; name < NUMBER_OF_INPUTS; name++) + { + printf ( "\n%s", stats[ name ] ); + } + printf ( "\n\n" ); + } + +/* ----------------------------------------- */ + + Note that as a side effect we have available the meaningful symbols + radiator_temperature etc. as indices into the array of status input names + and the symbol NUMBER_OF_INPUTS available for use as a terminator in the + 'for' loop. This is quite legal because sizeof is a pseudo-function and the + value is evaluated at the time of compilation and not when the program is + executed. This means that the result of the division in the macro is + calculated at the time of compilation and this result is used as a literal + in the 'for' loop. No division takes place each time the loop is executed. + + To illustrate the point I would like to tell you a little story which is + fictitious, but which has a ring of truth about it. + Your employer has just landed what seems to be a lucrative contract with + an inventor of a completely new type of engine. We are assured that after + initial proving trials one of the larger Japanese motor manufactures is + going to come across with umpteen millions to complete the development of + the design. You are told to write a program which has to be a simple and + straightforward exercise in order to do the job as cheaply as possible. + Now, the customer - a some-what impulsive type - realises that his + engine is not being monitored closely enough when it starts to rapidly + dis-assemble itself under high speed and heavy load. You have to add a + few extra parameters to the monitoring program by yesterday morning! + You just add the extra parameters into the enumand the array of pointers + to the character strings. So: + +enum status_input_names +{ radiator_temperature, + radiator_pressure, + fuel_temperature, + fuel_pressure, + oil_temperature, + oil_pressure, + exhaust_manifold_temperature + }; + + Let's continue the story about the Japanese purchase. Mr. Honda ( jun ) has + come across with the money and the result is that you are now a team leader + in the software section of Honda Software ( YourCountry ) Ltd. The project of + which you are now leader is to completely rewrite your monitoring program and + add a whole lot of extra channels as well as to make the printouts much more + readable so that your cheap, cheerful, and aesthetic-free program can be sold + as the "Ultimate Engine Monitoring Package" from the now world famous Honda + Real-time Software Systems. You set to work, Honda et. al. imagine that there + is going to be a complete redesign of the software at a cost of many million + Yen. You being an ingenious type have written the code so that it is easy to + enhance. + + The new features required are that the printouts have to be printed with the + units of measure appended to the values which have to scaled and processed so + that the number printed is a real physical value instead of the previous + arrangement where the raw transducer output was just dumped onto a screen. + + What do you have to do? + + Thinking along the line of "Get the Data arranged correctly first". + You take you old code and expand it so that all the items of information + required for each channel are collected into a struct. + +enum status_input_names +{ + radiator_temperature, + radiator_pressure, + fuel_temperature, + fuel_pressure, + oil_temperature, + oil_pressure, + exhaust_manifold_temperature, + power_output, + torque + }; + +typedef struct channel +{ + char *name; /* Channel Name to be displayed on screen. */ + int nx; /* position of name on screen x co-ordinate. +*/ + int ny; /* ditto for y */ + int unit_of_measure; /* index into units of measure array */ + char value; /* raw datum value from 8 bit ADC */ + char lower_limit; /* For alarms. */ + char upper_limit; + float processed_value; /* The number to go on screen. */ + float offset; + float scale_factor; + int vx; /* Position of value on screen. */ + int vy; + }CHANNEL; + +enum units_of_measure { kPa, degC, kW, rpm, Volts, Amps, Newtons }; + +char *units { "kPa", "degC", "kW", "rpm", "Volts", "Amps", "Newtons" }; + +CHANNEL data [] = +{ + { "radiator temperature", + { "radiator pressure", + { "fuel temperature", + { "fuel pressure", + { "oil temperature", + { "oil pressure", + { "exhaust manifold temperature", + { "power output", + { "torque", + }; + +#define NUMBER_OF_INPUTS sizeof (data ) / sizeof ( data[0] ) + +Now the lesson preparation is to find the single little bug in the above +program fragment, to finish the initialisation of the data array of type +CHANNEL and to have a bit of a crack at creating a screen layout +program to display its contents. Hint: Use printf(); +( Leave all the values which originate from the real world as zero. ) + + + Here are some more tips for young players. + + 1) Don't get confused between the logical equality operator, + + == + + and the assignment to a variable operator. + + = + + This is probably the most frequent mistake made by 'C' beginners, and + has the great disadvantage that, under most circumstances, the compiler + will quite happily accept your mistake. + + 2) Make sure that you are aware of the difference between the logical + and bit operators. + + && This is the logical AND function. + || This is the logical OR function. + The result is ALWAYS either a 0 or a 1. + + & This is the bitwise AND function used for masks etc. + The result is expressed in all the bits of the word. + + 3) Similarly to 2 be aware of the difference between the logical + complementation and the bitwise one's complement operators. + + ! This is the logical NOT operator. + ~ This is the bitwise ones complement op. + + Some further explanation is required. In deference to machine efficiency a + LOGICAL variable is said to be true when it is non-zero. So let's set a + variable to be TRUE. + + 00000000000000000000000000000001 A word representing TRUE. + Now let's do a logical NOT !. + 00000000000000000000000000000000 There is a all zero word, a FALSE. + + 00000000000000000000000000000001 That word again. TRUE. + Now for a bitwise complement ~. + 11111111111111111111111111111110 Now look we've got a word which is + non-zero, still TRUE. + + Is this what you intended? + + 4) It is very easy to fall into the hole of getting the + '{' & '}'; '[' & ']'; '(' & ')'; symbol pairs all messed up and the + computer thinks that the block structure is quite different from that + which you intend. Make sure that you use an editor which tells you the + matching symbol. The UNIX editor vi does this provided that you turn + on the option. Also take great care with your layout so that the block + structure is absolutely obvious, and whatever style you choose do take + care to stick by it throughout the whole of the project. + A personal layout paradigm is like this: + + Example 1. + +function_type function_name ( a, b ) +type a; +type b; +{ + type variable_one, variable_two; + + if ( logical_expression ) + { + variable_one = A_DEFINED_CONSTANT; + if ( !return_value = some_function_or_other ( a, + variable_one, + &variable_two + ) + ) + { + error ( "function_name" ); + exit ( FAILURE ); + } + else + { + return ( return_value + variable_two ); + } + } /* End of "if ( logical_expression )" block */ + } /* End of function */ + + This layout is easy to do using vi with this initialisation script + in either the environment variable EXINIT or the file ${HOME}/.exrc:- + +set showmode autoindent autowrite tabstop=2 shiftwidth=2 showmatch wm=1 + + Example 2. + +void printUandG() +{ + char *format = +"\n\ + User is: %s\n\ + Group is: %s\n\n\ + Effective User is: %s\n\ +Effective Group is: %s\n\n"; + + ( void ) fprintf ( tty, + format, + passwd_p->pw_name, + group_p->gr_name, + epasswd_p->pw_name, + egroup_p->gr_name + ); + } + + Notice how it is possible to split up format statements with a '\' as + the last character on the line, and that it is convenient to arrange + for a nice output format without having to count the + field widths. Note however that when using this technique that the '\' + character MUST be the VERY LAST one on the line. Not even a space may + follow it! + + In summary I *ALWAYS* put the opening brace on a new line, set the tabs + so that the indentation is just two spaces, ( use more and you very quickly + run out of "line", especially on an eighty column screen ). If a statement + is too long to fit on a line I break the line up with the arguments set out + one to a line and I then the indentation rule to the parentheses "()" + as well. Sample immediately above. Probably as a hang-over from a particular + pretty printing program which reset the indentation position after the + printing of the closing brace "}", I am in the habit of doing it as well. + Long "if" and "for" statements get broken up in the same way. This is + an example of it all. The fragment of code is taken from a curses oriented + data input function. + + /* + ** Put all the cursor positions to zero. + */ + + for ( i = 0; + s[i].element_name != ( char *) NULL && + s[i].element_value != ( char *) NULL; + i = ( s[i].dependent_function == NULL ) + ? s[i].next : s[i].dependent_next + ) + { /* Note that it is the brace and NOT the */ + /* "for" which moves the indentation level. */ + s[i].cursor_position = 0; + } + + /* + ** Go to start of list and hop over any constants. + */ + + for ( i = edit_mode = current_element = 0; + s[i].element_value == ( char *) NULL ; + current_element = i = s[i].next + ) continue; /* Note EMPTY statement. */ + + /* + ** Loop through the elements, stopping at end of table marker, + ** which is an element with neither a pointer to an element_name nor + ** one to a element_value. + */ + + while ( s[i].element_name != ( char *) NULL && + s[i].element_value != ( char *) NULL + ) + { + int c; /* Varable which holds the character from the keyboard. */ + + /* + ** Et Cetera for many lines. + */ + + } + + Note the commenting style. The lefthand comments provide a general +overview of what is happening and the righthand ones a more detailed view. +The double stars make a good marker so it is easy to separate the code and +the comments at a glance. + + The null statement. + + You should be aware that the ";" on its own is translated by the compiler +as a no-operation statement. The usefullness of this is that you can do +little things, such as counting up a list of objects, or positioning a pointer +entirely within a "for" or "while" statement. ( See example above ). +There is, as always, a flip side. It is HORRIBLY EASY to put a ";" at the +end of the line after the closing right parenthesis - after all you do just +that for function calls! The suggestion is to both mark deliberate null +statements with a comment and to use the statement "continue;". Using +the assert macro will pick up these errors at run time. + + The assert macro. + + Refer to the Programmers Reference Manual section 3X and find the +documentation on this most useful tool. + + As usual an example is by far the best wasy to explain it. + +/* ----------------------------------------- */ + +#ident "@(#) assert-demo.c" + +#include +#include + +#define TOP_ROW 10 +#define TOP_COL 10 + +main() +{ + int row, col; + + for ( row = 1; row <= TOP_ROW; row++); + { + assert ( row <= TOP_ROW ); + for ( col = 1; col <= TOP_COL; col++ ) + { + assert ( col <= TOP_COL ); + printf ( "%4d", row * col ); + } + printf ( "\n" ); + } + } + +/* ----------------------------------------- */ + + Which produces the output:- + +Assertion failed: row <= TOP_ROW , file assert-demo.c, line 15 +ABORT instruction (core dumped) + + It does this because the varable "row" is incremented +to one greater than The value of TOP_ROW. + + Note two things: + + 1) The sense of the logical condition. The assert is asserted + as soon as the result of the logical condition is FALSE. + Have a look at the file /usr/include/assert. + Where is the ";" being used as an empty program statement? + + 2) The unix operating system has dumped out an image of the executing + program for examination using a symbolic debugger.

The initialising statement is +executed once, but to allow for the need to initialise several separate +variables the assignment statements may be separated by commas.

The method +of choice is - I believe - that presented above. The #if defined( LANGUAGE ) +gives us an easy method of changing the source code to suit the new sales +area. Another possibility is to put all the text output needed from a program +into a file. The file would have to have a defined layout and some consistent +way of `getting at' the message strings. + + From a commercial point of view this may or may not be a good business plan. +Quite definitely it is an absolute no no to scatter a mass of string literals +containing the messages and message fragments all over your program script. + + There are two more methods of altering the program flow. + + 1 ) The goto a label. + 2 ) The setjump / longjmp library routines. + + The concept of the go to a label construction has had reams of literary +verbiage written about it and this author does not intend to add to the pile. +Suffice it to say that a goto is a necessary language construct. There are a +few situations which require the language to have ( in practice ) some form of +unconditional jump. Treat this statement with great caution if you wish your +code to be readable by others. An example of legitimate use. + + for ( a = 0; a < MATRIX_SIZE; a++ ) + { + for ( b = 0; b < MATRIX_SIZE; b++ ) + { + if ( process ( matrix, a, b )) goto bad_matrix; + } + } + return ( OK ); + +bad_matrix: + + perror ( progname, "The data in the matrix seems to have been corrupted" ); + return ( BAD ); + + This is one of the very few "legitimate" uses of goto, as there is no +"break_to_outer_loop" in `C'. Note that some compilers complain if the label +is not immediately followed by a statement. If your compiler is one of these +naughty ones, you can put either a `;' or a pair of braces `{}' after the +`:' as a null statement. + + An example of a program package which makes extensive use of the goto is the +rz and sz modem communications protocol implementation by Chuck Forsberg of +Omen Technology. You should download it and study the code, but do remember +that the proof of the pudding argument must apply as the rz & sz system has +become extremely popular in its application because it works so well. + + The other method of changing program flow is the setjump and longjmp pair of +library functions. The idea is to provide a method of recovery from errors +which might be detected anywhere within a large program - perhaps a compiler, +interpreter or large data acquisition system. Here is the trivial example: + +#ident "set_jmp_demo.c" + +#include +#include + +jmp_buf save; + +main() +{ + char c; + + for ( ;; ) /* This is how you set up a continuous loop. +*/ + { + switch ( setjmp( save )) + { +case 0: + printf ( "We get a zero returned from setjmp on setup.\n\n"); + break; /* This is the result from setting up. */ + +case 1: + printf ( "NORMAL PROGRAM OPERATION\n\n" ); + break; + +case 2: + printf ( "WARNING\n\n" ); + break; + +case 3: + printf ( "FATAL ERROR PROGRAM TERMINATED\n\nReally Terminate? y/n: " ); + fflush ( stdout ); + scanf ( "%1s", &c ); + c = tolower ( c ); + if ( c == 'y' ) return ( 1 ); + printf ( "\n" ); + break; + +default: + printf ( "Should never return here.\n" ); + break; + } + process (); + } + } + +process () +{ + int i; + + printf ( "Input a number to simulate an error condition: " ); + fflush ( stdout ); + scanf ( "%d", &i ); + i %= 3; + i++; /* So that we call longjmp with 0 < i < 4 */ + longjmp ( save, i); + } + + Although in this silly little demo the call to longjmp is in the same file +as the call to setjmp, this does not have to be the case, and in the practical +situation the call to longjmp will be a long way from the call to setjmp. The +mechanism is that setjmp saves the entire state of the computer's CPU in a +buffer declared in the jmp_buf save; statement and longjmp restores it exactly +with the exception of the register which carries the return value from longjmp. +This value is the same as the second argument in the longjmp call - i in our +little demo. This means, of course, that the stack and frame pointer registers +are reset to the old values and all the local variables being used at the time +of the longjmp call are going to be lost forever. One consequence of this is +that any pointer to memory allocated from the heap will also be lost, and +you will be unable to access the data stored in the buffer. This is what the +jargonauts call "memory leakage", and is really very difficult bug to find. +Your program runs out of dynamic memory long before it should. Take care. +So you have to keep a record of the buffers' addresses and free them +before the call to longjmp. + +More details later on when we learn about the heap memory allocation routines. + +Copyright notice:- + +(c) 1993 Christopher Sawtell. + +I assert the right to be known as the author, and owner of the +intellectual property rights of all the files in this material, +except for the quoted examples which have their individual +copyright notices.

Never rely on them + defaulting to int. + + -- Pay a little care to the ternary operator ? :, and parenthesize + heavily. A very few compilers have problems with the default + order of evaluation for the ternary operator. + + -- Never ever name a variable identically to a function. This is + most especially true of statics or globals. This sort of error + can cause weird hidden linker problems which cause bizarre + results at runtime and are difficult to trace. + + -- Never ever name a screen, form, data field etc identically to a + variable or function as this can cause weird and non-reported + linker errors in the final executable which can be very + difficult to locate. + + -- Do not nest comments. If you want to block off a section of + code temporarily, use #ifdef/#endif. eg. + + ...code... + #ifdef JUNK /* Unwanted code */ + ...more code... + #endif /* JUNK */ + ...yet more code... + + -- Run PC-Lint on all code, and handle ALL errors and warnings. + + -- Read the "Frequently Asked Questions" document and understand + fully. + + -- Read K&R thoroughly and everywhere it mentions "implementation + dependant", or "new" features not "supported by all compilers", + avoid those areas. Examples are bit fields, passing structures + to functions, returning structures from functions, and the + volatile type. These are not supported by all compilers. + + -- In areas where the ANSI standard advances on the old K&R, but + still allows the K&R form, follow K&R. An example is using + function pointers. If you are unsure what areas this covers, + don't worry, just stick with K&R. eg. + + Given: + + int (*prj_afunc) (); /* Pointer to function which returns int */ + + ANSI allows the pointed to function be called as so: + + prj_afunc (xxx, yyy); + + K&R specifies that it should be called: + + *prj-afunc (xxx, yyy); + + Use the K&R form, which ANSI still allows, and all compilers + support. + + -- Do not use the new // comments. Stay with the /* comment */ + form. + + -- Do not indent #ifdefs, #defines, #pragmas, or other preprocessor + directives. Some compilers allow code as such: + + #ifdef DEBUG + #define TEST 1 + #endif + + or + + #ifdef FINAL + # ifdef DEBUG + # define TEST 1 + # endif + #endif + + But by no means all. Use white space if needed to delineate + #ifdef/endif blocks and comment liberally: + + #ifdef FINAL + + #ifdef DEBUG + #define TEST 1 + #endif /* DEBUG*/ + + #endif /* FINAL */ + + -- Do not use the ANSI string literal concatenation features. eg. + + printf ("This is ANSI but" + "unportable code.\n"); + + for long string literals. Under ANSI the the compiler should + concatenate the two string literals into one, but not all ANSI + compilers support this feature yet. If you need a very long + string literal use a form as so: + + printf ("%s%s", + "this is", + "portable code.\n"); + + or just use a very long string literal. + + -- Stay away from ints except for trash and temp values. Ints vary + in size depending upon the memory model under DOS, and legally + may be any size between shorts and longs inclusive. + + Try to use shorts or longs if possible, as these are of fairly + constant size on most platforms. On most platforms, but by no + means all, shorts are usually words and longs word pairs. + + -- Beware of assigning a pointer of one type to a pointer of a + higher type. Most platforms seem to insist that the addresses + stored in pointers are alligned per the pointer's base type. + + What this means is that the value stored in a pointer to a long, + in itself will be alligned as a long is. If longs are alligned + on even word boundaries, then so will the value of long pointer. + + This can result in memory allignment errors which can be + extremely difficult to track down. Casting will not help. + + DOS has few memory allignment requirements, but for Unix and VMS + you can expect types to be alligned to their sizes (see the + compiler manuals for specifics). What this means to pointers is + that with code such as: + + short *pj2_value; /* Assume that shorts are alligned to words */ + long *pj4_number; /* and longs to even word boundaries */ + + pj4_number = pj2_value; + + that the value assigned to pj4_number may be as far as two bytes + different from that in pj2_value. ie + + Let's say that the address stored is pj2_value is: + + *pj2_value == 0000:0006 /* Alligned to word */ + + and you make the assignment: + + pj4_number = pj2_value; + + After this, the value of pj4_number will be either 0000:0004, + or 0000:0008 to shift it to even word allignment. The + direction of the shift seems to be compiler/implementation + dependant. + + This bug is often erratic at runtime depending upon the + allignment of automatics. This sort of bug is especically + difficult to track when coming up from a void pointer. + + -- Be wary of relying on memory allignment in structures and + unions. Different compiler implmentations allign differently, + and #pragmas or command line arguments to the compiler can + change allignment at compile time. See the compiler manuals for + specific details. + + This will usually require you to either read in each member + individually, or to perform explicit padding when reading + structure data from disk. eg. lic1.c & v_lic_pad() in the Axiom + library. + + -- Where possible use sizeof(identifier) rather than sizeof(type) + or a #defined constant. This can help in tracing down bugs and + makes for greater readability. eg. + + #define M_DATA 100 + short aj2_numbers[M_DATA]; + + /* This example requires the reader to remember that + aj2_numbers has M_DATA elements, is overly complex, and + presumes that aj2_numbers will always be shorts. This code + will likely break if anything is later changed. */ + + memcpy (aj2_numbers, pj2_input, M_DATA * sizeof (short)); + + /* This is ideal -- sizeof(aj2_numbers) will return the total + space allocated to the array, no matter what the type may be, + or what is changed later. It makes no assumptions of the + reader. */ + + memcpy (aj2_numbers, pj2_input, sizeof (aj2_numbers)); + + -- Beware of comparing structures or unions with functions such as + memcmp() as the padding/allignment spaces will have random and + likely different values. If you need to compare structures + you'll have to do it member by member. + + -- Never assign structures to each other directly. Some compilers + allow structure assignments, some don't. + + struct t_data s_struc1; + struct t_data s_struc2; + + s_struc2 = s_struc1; /* Unportable code */ + + Note however that you can copy structures via pointers as need + be: + + struct t_data *ps_struc1; + struct t_data *ps_struc2; + + ps_struc1 = xxx; + ps_struc2 = yyy; + + *ps_struc2 = *ps_struc1; /* Copy structure 1 to 2 */ + + Rather than assigning each member over individually. The + functions memcpy() and memmove() are other portable ways. + + -- Beware of passing chars or shorts to functions. These get + promoted to ints, and with some compilers problems from there on + out abound horrendously. This is especially true of chars where + some compilers occassionally extract the wrong byte from the + promoted int in the recieving function. + + -- Be careful passing floats to functions as some compilers promote + floats to doubles when passing them as an argument. This can + cause spurious warnings and and strange side effects. + + -- Explicitly cast assignments and expressions as needed, and + carefully watch that you really don't need to make those + identifiers of that type originally.

Why was only the DOS batch file and "Stuff-key-buffer method" + (SETENVAR.C) included in the original SNIPPETS? + + +A. The reason that I only included the "batch&stuff" method in my SNIPPETS + collection is simply that it's the *only* method you can rely on if your + program is going to be distributed. Quite simply, there is *NO* safe, + documented way under DOS to set an environment variable in the master + environment block - period! By back-tracking PSPs or MCBs, you can try + to locate the master environment and change it. You can also try to use + Int 2Eh, the command processor's "back door". But all of these methods + suffer from several shortcomings: + +1) Someone using the program might be using 4DOS, COMMAND PLUS, or some other + COMMAND.COM replacement. These don't always do things the same way as + COMMAND.COM and the diferences can cause you to crash, roll, & burn! For + example, several COMMAND.COM replacements allow the master environment + block to be located in extended, expanded, or high memory. In such a case, + backtracking PSPs or MCBs is less than useless, they're guranteed to + yield undefined errors. + +2) Int 2Eh seems to be the most universally supported, but cannot be used in + a program invoked from a batch file. The book, "Undocumented DOS" details + some procedures for making an Int 2Eh call safer but, again, these + techniques rely on implementation features of COMMAND.COM which might not + be available in alternate command processors. + +3) Even if everything else is safe, you still need a way of error trapping in + case your new environment variable might overwrite the end of the + available master envirnment block. This error trapping in inherent in + COMMAND.COM and alternate command processors (one reason why using the + Int 2Eh back door is potentially the safest way to try), but if you try to + modify things manually, you're on your own. If you do overwrite the end of + the master environment block, you'll have automatically corrupted your MCB + chain and possibly set yourself up for some *really* nasty surprises! + +4) Finally, there's the very fundamental question of which environment block + really is the master? Say you're in your comm program and hit the "shell + to DOS" key. A secondary copy of the command processor, be it COMMAND.COM + or whatever, is spawned and you're off and running. If you now run your + program from this secondary DOS shell, is its environment block the master + or is it the one from which you ran your comm program? Worse yet, + depending on how you set up CONFIG.SYS, the secondary shell may have a + considerably smaller environment block than the original. Despite having + set the "/E:" switch, your secondary shell will likely only have an + environment block whose size is equal to the current block size rounded + up to the next paragraph boundry. If you trace PSPs, you'll find the + secondary shell which you stand a good chance of over-running due to the + difference in the block size. If you trace MCBs, you'll find the real + master block, but then your changes will have disappered when you return + to your comm program, defeating the purpose of your program in the first + place. + + The inability to alter a parent program's environment block isn't a DOS + exclusive, BTW - it's an inheritance from Unix where the same limitation + applies. + + Finally, SNIPPETS now includes several of these alternate unsafe ways of + setting the master environment. INT2E.ASM & CCOMCALL.C together provide + access to the DOS command processor back door, GLBL_ENV.C provides means + for TC/TC++/BC++ and MSC/QC programmers to modify the master environment + by backtracking PSP pointers, and MCB_ENV.C serves the same purpose only + using the MCB tracking method. diff --git a/reference/C/CONTRIB/SNIP/errfix.c b/reference/C/CONTRIB/SNIP/errfix.c new file mode 100755 index 0000000..05fdc39 --- /dev/null +++ b/reference/C/CONTRIB/SNIP/errfix.c @@ -0,0 +1,52 @@ +/* +** ERRFIX.C - redirect stderr to some other file under MS-DOS +** +** by Bob Jarvis +*/ + +#include +#include +#include +#include + +char *usage = "ERRFIX [filename] [prog] { {parm1} {parm2} ... {parmN} }\n" + " Redirects stderr to another file, then invokes a program\n" + " which will inherit the new definition of stderr.\n\n" + "Parameters:\n" + " filename (required) - the name of the file stderr should\n" + " be redirected to.

Although these are often treated +the same, they are actually handled in subtly different manners. The +difference in the way these are processed allows a great deal of +flexibility in allowing users to interrupt an executing program. + +When a program is executed, the Ctrl-C Interrupt 23h is set up to +point to a default error handler. This handler is called whenever a +Ctrl-C character is detected in the keyboard input buffer. When a +program terminates in any way, MS-DOS resets the Interrupt 23h vector +to its default state. Note that the Ctrl-C character in the input +buffer is only recognized - and an Interrupt 23h generated - when +retrieving characters from the buffer and if BREAK ON is set. + +The Ctrl-Break Interrupt 1Bh works somewhat differently, though +usually in concert with Interrupt 23h. Whenever the ROM BIOS detects +the Ctrl-Break key combination, the keyboard buffer is flushed and a +Ctrl-C key combination is stuffed in place of the previous contents. +This Ctrl-C will later be detected and processed by Interrupt 23h. +Ctrl-Break processing therefore offers more immediate response than +Ctrl-C processing if the default action is overridden. + +Several caveats are in order here, however. First is the fact that, +unlike Interrupt 23h, MS-DOS does not restore the default state of +Interrupt 1Bh upon program termination. Second is that while Ctrl-C +processing is standardized among the various machines utilizing both +MS-DOS and PC-DOS, Ctrl-Break processing is much less standardized. +Finally, since processing either ultimately relies on trapping +Ctrl-C, either may be ignored for a long period because of the way +that Ctrl-C is detected. + + +HANDLING USER-GENERATED EXCEPTIONS +---------------------------------- + +DOS's default Ctrl-C handler is triggered whenever the Ctrl-C +character is detected in the input buffer. DOS's response is to +simply close all files which were opened using handle functions and +to terminate the program. The limitations of this approach and the +desirability of providing your own exception processing is obvious. + +An equally obvious solution to the default Ctrl-C handler's problems +is to explicitly do your own Ctrl-C exception processing. CCTRAP.ASM +installs and de-installs you own customized exception handler. Note +that the code is written to accept the address of a function specified +with an explicit segment and offset. + +Also note that an explicit de-installation function is provided +despite the fact that DOS restores the default Int 23h vector upon +program termination. The reason this is provided is that you should +always de-install a Ctrl-C interrupt trap before you spawn a child +process. Within your program, if you need to spawn such a process +through any mechanism other than spawning a subordinate shell (more +on this in a second), you should explicitly de-install your interrupt +handlers and re-install them when the subordinate process returns. As +noted, this is unnecessary when the subordinate process is a DOS +shell such as COMMAND.COM, since the shell will reset the interrupts +to their defaults during execution. + +Ctrl-Break processing is much more problematical, though potentially +more powerful. The first problem to deal with is how to assure that +the default Int 1Bh Ctrl-Break handler will be restored upon program +termination. The de-installation function therefore becomes mandatory +in this context rather than optional as in the case of the Int 23h +handler. CBTRAP.ASM shows a sample Ctrl-Break handler. Since Ctrl-Break +processing is much less standardized than Ctrl-C processing, the +safest way to deal with it is to simply set a flag, "cbrcvd", which +informs your program that a Ctrl-Break has been received. Your +program may then poll this flag and take appropriate actions at +"safe" times within your program. + + +WHERE THE CARET-C COMES FROM +---------------------------- + +There's still nothing new here and nothing to prevent the ugly "^C" +being printed to the screen. This is because it is actually printed +by the BIOS during Int 9 processing, long before DOS ever sees it. +What this means is that even though the code in CCTRAP.ASM and +CBTRAP.ASM is fine, it still only provides a framework for solving +our problem. + +TRAPFLAG.ASM is the final trick to banish the "^C". The actual ISR +has to muck around quite a bit with the keyboard hardware, as is to +be expected of an Int 09h replacement. Whenever a Ctrl-C or Ctrl- +Break is detected, it is trapped, and our exception handler called in +place of the original Int 09h handler, after discarding the trapped +key codes. + +Referring to TRAPFLAG.ASM, note that since I need to trap both Ctrl-C +and Ctrl-Break, I adopt the flag approach introduced in CBTRAP.ASM +for dealing with both Ctrl-C and Ctrl-Break processing. Now, rather +than supplying an explicit exception vector, I merely set a global +flag to inform me if either exception has occurred and accept the +responsibility of processing the exceptions within the body of my +program. I've added an extra bit of versatility here by posting +different non-zero values to the flag, "ccrcvd" depending on whether +the exception was a Ctrl-C or Ctrl-Break. + +TRAPDEMO.C is a short C program demonstrating the use of the combined +Ctrl-C/Ctrl-Break handler. Using this approach, your carefully +crafted screens need never more be cluttered with the "^C" uglies. + + +SYSTEM-GENERATED EXCEPTIONS +--------------------------- + +It's usually desirable, in any professional-looking program, to +explicitly trap the Int 24h critical error interrupt to process +system-generated exceptions. CERRINST.ASM is a portable critical +error handler installation program functionally equivalent to the +[_]hardxxx() package in Borland C++ and Microsoft C++ compilers, and +the ceror_xxx() package in Zortech C++. + +It's obvious that writing code to intercept DOS critical error +exceptions is just as simple as intercepting Ctrl-C or Ctrl-Break +exceptions. The real challenge in writing critical error handlers is +in interpretation of the nature of the exception. + +The critical error handler requires more information in order to +decide what action to take than does a Ctrl-C handler. All of this +information is passed in the CPU's registers. Just like a typical +compiler vendor's critical error handler, CERRINST.ASM will simply +pass these registers and leave their interpretation to you. In +CERRINST.ASM, the information required for intelligent critical error +processing is posted in 4 global variables, cedevdvr, cetype, +ceerror, and cereturn. + +Next you need to determine what your program requires of a critical +error handler. CERRTRAP.ASM is a skeletal, yet robust critical error +function which may be called from the handler in CERRINST.ASM. +CERRTRAP.ASM assumes you have set up the following specific error +handlers in the global variables provided: + +FAT error (*FAT_err)(); +Disk read error (*read_err)() +Disk write error (*write_err)() +Terminal error (*term_err)(), +Printer out of paper (*no_paper)(), +All other errors (*fixup_ret)(), + +In the case of an unrecognized error, fixup_ret() is called. A simple +skeleton for this function would be: + +#include /* for _osmajor */ +extern int exerr; /* DOS extended error posted by CERRTRAP.ASM */ +extern int rmvbl; /* removable media flag posted by CERRTRAP.ASM */ +extern int locus; /* extened error locus posted by CERRTRAP.ASM */ +extern int class; /* extened error class posted by CERRTRAP.ASM */ +extern int suggest; /* suggested action posted by CERRTRAP.ASM */ + +int fixup_ret(void) +{ + if (2 < _osmajor) + { + /* analyze DOS extended error information */ + + return appropriate_error_code; + } + + /* cleanup */ + + return 2; /* abort */ +} + +In customing your specific critical error handler functions, there +are several important restrictions to keep in mind. The first is that +no DOS system services may be requested other than Interrupt 21h +functions 01h-0Ch (character I/O), 30h (get DOS version number), and +59h (get extended error information). All registers except AL must be +preserved since DOS sets them up for processing Retry returns prior +to invoking the critical error interrupt. + +Finally, the handler must return with an IRET instruction, passing a +return code in AL to tell DOS what to do next. The available codes +and their actions under various DOS versions are: + + 0 - Ignore + 1 - Retry + 2 - Abort + 3 - Fail (DOS 3.3 and later) diff --git a/reference/C/CONTRIB/SNIP/ext_keys.c b/reference/C/CONTRIB/SNIP/ext_keys.c new file mode 100755 index 0000000..9ec2846 --- /dev/null +++ b/reference/C/CONTRIB/SNIP/ext_keys.c @@ -0,0 +1,56 @@ +/* +** ext_getch() +** +** A getch() work-alike for use with extended keyboards. +** +** Parameters: none +** +** Returns: Extended key code as follows: +** 0->255 Normal key +** 256->511 Numeric pad key or Function key +** 512->767 Cursor pad key or Numeric pad +** "duplicate" key (Enter, /, *, -, +) +** +** Original Copyright 1992 by Bob Stout as part of +** the MicroFirm Function Library (MFL) +** +** This subset version is hereby donated to the public domain. +*/ + +#include +#include + +#define LoByte(x) ((unsigned char)((x) & 0xff)) +#define HiByte(x) ((unsigned char)((unsigned short)(x) >> 8)) + +int ext_getch(void) +{ + int key;

When I say "small", I mean just that - but the scope of the +information I wanted to present really didn't fit well into that little hole, +so it turned out a little larger than I had initially hoped. However, I think +the effort was worth it - I know it was for me, since although I've done code +which deals with ostream, I hadn't fooled at all with istream derived +facilities, and learned some new things in the process. + +I can't really cite any single reference on iostreams that might prove useful +for those wanting to go further other than the AT&T iostreams reference +manual (my copy is out on loan at the moment so I can't quote the ISBN +number). I have never come across one which is more complete than this +reference, and most other references (including documentation from MSC/C++C, +Borland, IBM etc.) tend to quote from it fairly liberally, but lack any of +the important information needed to put it all together. While Microsoft's +C++ tutorial reference has some great hints for getting started in iostream +manipulators, it lacks in providing any information on interfacing to the +iostream classes themselves. + +Hopefully the information I've provided below will make some sense. It is as +complete as I could make it without really going overboard. Most of the +ostream related code is gleaned from my own library, but the rest is brand +new. + +The text of this tutorial and the accompanying source code are donated to the +public domain. + + +Tutorial in iostreams --------------------- + +This little project started out with the following aims: + +A) To define a simple input/output object, one that consumes bytes sent to + it and generates data for input into a sample program. It should there- + fore feature a "read" and "write" function. The object created is simply + a loopback buffer - input is queued immediately for output in FIFO (first + in first out) fashion. + +B) To create a streams interface for this object, so that existing facili- + ties for I/O in the AT&T streams classes can be used directly in a + polymorphic fashion (ie. make use of C++ inheritance & virtual dispatch). + + Specifically, I wanted to demonstrate the following aspects of iostreams: + + - Use of buffered vs. unbuffered I/O + + - Using the streams buffer for both input and output operations. (an + interface to iostream, rather than just istream or ostream) + + - How the put, get and putback buffers work + +C) To write a trivial application which uses both components and provide a + means of interactively demonstrating how it all works. + + +A - The I/O Object ---------------- + +class Myio; + +This class is simply a front-end for a circular buffer. Input bytes are added +at the head, and read from the tail. It is fixed in size, set by the +constructor. + +Two read/write functions are provided to access any contained data: + + int Myio::read (char * buf, int max); + int Myio::write (char const * buf, int len); + +These are both non-blocking calls which return the number of bytes read or +written. They know nothing about line delineation - only about raw bytes, as +would be the case for almost any I/O device. + +In addition, an internal flag is maintained to indicate when a write results +in a buffer 'overflow' (an attempt to write more bytes than will fit in the +buffer) and 'underflow' (an attempt to read an empty buffer). These flags +reflect the last write and read calls respectively, and are reset or set on +each write or read call. The members Myio::readok() and Myio::writeok() +rturn the settings as a boolean value. + +A Myio object can also optionally create a stream. It is created and comes +into life when the member function Myio::stream() is called. If it was +previously created, this function simply returns a reference to the existing +stream. The stream, if it exists, is deleted by the destructor. + +Myio's stream is an iostream, which inherits all of the abilities of both +ostream (for output) and istream (for input), including all operators. This, +of course, is the primary benefit of using streams! + + +B - The Streams Interface ----------------------- + +class Mystreambuf; class Mystreambase; class Mystream; + +Three classes as above are used. Mystreambuf derives from streambuf, and is +responsible for the input output operations and buffering on behalf of a Myio +object. Mystreambase is used as a base class for Mystream to assist in the +initialisation of the (My)streambuf passed to the iostream constructor. + +The iostream side is in fact very simple. Nothing really needs to be +overridden, and all of the work is done in Mystreambuf, where all the action +really takes place. + +The relationship between the ios/stream classes and the streambuf family is +one of delegation rather than inheritance. The user/application accesses +streambuf I/O via the stream object, not directly. A class diagram showing +the basic iostream classes and our classes would look like: + + + _ istream _ / \ ios -- ostream -- iostream \ \ \ Mystream \_____ +Mystreambase _/ | | (owns) | streambuf -- Mystreambuf + + +All relationships, except the one marked "(owns)", indicate inheritance. The +'owns' relationship is where the delegation occurs. ios is inherited +virtually, so that there is only one combined 'ios' object at the root of the +streams inheritence tree. + +Within Mystreambuf, we need to override the functions responsible for actual +input and output. But first, let's discuss how this streambuf works. + +Mystreambuf uses a single buffer, using the default buffer size allocated for +any streambuf (under most operating systems, this will be 1024 bytes). Since +we are dealing with both input and output operations, and these operations +are independent so far as the streambuf is concerned (as is the case with, +for example, serial I/O, but *not* the case with files), the buffer is split +into two; the first half is used for writing, the second for reading. + +The buffer used for writing is called the "put" buffer. Nothing mysterious +there - when full, streambuf::overflow() function is called, and via virtual +dispatch calls our Mystreambuf::overflow() which takes the contents of the +buffer and writes it to the output device. + +The read - or "get" - buffer is slightly more complex. There are occasions in +dealing with an input stream where it is convenient to know what's next +without actually removing it from the stream. That way, you can use the next +character as an indication of what to do next. For example, if you're parsing +a number, you want to know whether or not the next character is a valid +digit, and stop parsing if it isn't. The read side therefore incorporates the +idea of a "putback" buffer - after being read, the character can be placed +back into the input stream. + +The putback buffer is entirely the responsibility of any streambuf derived +class. It most you need to support a one character putback buffer - it is not +valid to remove, and then restore, more than one character from the stream. +It is also not valid put 'putback' any character but the one that was the +result of the last 'get'. It really must be "put back", not any old +character "pushed" (you could actually support 'pushing' data into the stream +if you wanted to, but you shouldn't use putback to do it). + +The get buffer is set up as: + + Offset 0 1 2 3 .... n | | | | to end of buffer | ++---+---+---+---------------------+ ^ ^ | +- Start of get buffer (where data +is read in) | +- Where data is putback + +Each time streambuf runs out of characters to give to its client, the +underflow() function is called. This fills the get buffer (get buffer size - +1, starting at offset 1) and reserves the first byte in case the previously +read character needs to be put back. + +streambuf provides internal pointers into the put, get and putback areas. All +of the I/O functions it provides handle these automatically. In our +underflow() and overflow() functions, we need to set these pointers according +to where and how much data is read in. + +I mentioned above that in our case, the input & output streams are +independant. That's not entirely the case - it may happen that when reading +from the Myio buffer we run out of data and need additional data in the +output stream buffer not yet written to Myio. We therefore flush the output +stream before retrieving any data by calling overflow() directly from within +underflow(). + +The sync() function is also overridden. This simply empties all buffers by +flushing the output buffer and discarding any buffered input. + + +C - The Application ----------------- + +The application itself is a simple menu, offering choice to send a line of +output to the IO object (via its stream), read one in, and dump/display +information both about the stream and Myio object. + +This added two other classes to the project: + + - myApplication: the actual application, implemented as a class. The + only way to go in C++. :-) + + - myList: a simple line input class, whose sole purpose in life is to + extract a linefeed delimited line from any istream object and return it + as a char const *. (I posted this code last week, but have since fixed + one minor bug I found in the process of developing Myio). + +A couple of subtle points - class myApplication uses a pointer to member +function it its menu selection. This is not the only way of doing this of +course, but I thought it was a good way of demonstrating a very C++ specific +concept, operator ->*, which does not exist at all in C. + +Additional notes are included in the source comments. + + +Making the application ---------------------- + +Hopefully this is a fairly simple thing to do - just compile the modules: + + Myiodemo.cpp Myio.cpp Mystream.cpp myLine.cpp + +and link them together. A simple makefile is provided - take a look at the +definitions at the top, adjust as desired, and type "make" (or nmake). If you +use any of Borland's compilers, just add the above files to a new project +called "Myiodemo.PRJ", set it to produce a .EXE (*not* Windows or PM based) +and press F9. + +Assuming a C++ compiler compatibile with cfront 2.1 and the presence of an +iostreans 1.2 library, the only non-portable part of this app is the use of +getch() from conio.h. This isn't easily provided under a UNIX system. You can +either fudge it by writing a getch() which switches into/out of 'raw' mode, +or use getchar() and clear everything up to and including a CR or NL after +the first character (the user still has to hit CR for input to get to the +program). + + + +EPILOGUE -------- + +Just some notes as to use of this code. If you need an output or input only +class, then you use ostream or istream wherever iostream is mentioned in this +example. Also, if you use buffered mode (you can support it or not - you can +even ignore the streambuf setting at your discretion), then you can use the +entire buffer rather than just half each for input output. + +If you interface to an input only object, you only need to override +streambuf::underflow(). Conversely, you override streambuf::overflow() for an +output only object. I have noticed that *some* implementations of iostreams +define the overflow() and underflow() methods as pure virtual functions, +whereas the AT&T default defines each as simply returning EOF. + +If portability is any concern, you may need to override the function you +aren't using in this fashion. The default sync() simply returns 0 (success), +but again, this is sometimes defined as a pure virtual, so you may need to +define it in your implementation. + +In some cases, you may wish to "switch" between unbuffered and buffered +modes. This is easily done by defining a function in Mystream which does it, +and this object is of course accessible in your I/O object (in this case +Myio). The only thing you need to remember is to flush all the buffers by +calling sync() when switching from buffered to unbuffered mode. + +Note also that some streambuf constructors take an existing buffer. This +means that you can use buffers already provided in your I/O object directly +rather than being forced to "double buffer" anything. Your buffer can also +be any size you like, subject to memory and other architecture constraints. + + +Enjoy! + +David Nugent - 3:632/348@fidonet.org +Moderor ('93-'94) of the FidoNet international C++ EchoMail conference diff --git a/reference/C/CONTRIB/SNIP/iscons.c b/reference/C/CONTRIB/SNIP/iscons.c new file mode 100755 index 0000000..b757d89 --- /dev/null +++ b/reference/C/CONTRIB/SNIP/iscons.c @@ -0,0 +1,39 @@ +/* +** iscons() +** +** A function to determine if a specified stream refers to the console. +** +** Original Copyright 1988-1991 by Bob Stout as part of +** the MicroFirm Function Library (MFL) +** +** This subset version is hereby donated to the public domain. +*/ + +#include +#include + +#define BOOL(x) (!(!(x))) + +int iscons(FILE *fp) +{ + union REGS regs; + + regs.x.ax = 0x4400; + regs.x.bx = (unsigned)fileno(fp); + intdos(®s, ®s); + if (0 == (regs.x.ax & 0x80)) + return 0; + return BOOL(regs.x.ax & 0x13); +} + +#ifdef TEST + +int main(void) +{ + fprintf(stderr, "stdin is%s redirected\n", + iscons(stdin) ?

Kercheval + [72450,3702] -- johnk@wrq.com + + + + +*IX SH style Regular Expressions +================================ + +The *IX command SH is a working shell similar in feel to the MSDOS +shell COMMAND.COM. In point of fact much of what we see in our +familiar DOS PROMPT was gleaned from the early UNIX shells available +for many of machines the people involved in the computing arena had +at the time of the development of DOS and it's much maligned +precursor CP/M (although the UNIX shells were and are much more +flexible and powerful then those on the current flock of micro +machines). The designers of DOS and CP/M did some fairly strange +things with their command processor and OS. One of those things was +to only selectively adopt the regular expressions allowed within the +*IX shells. Only '?' and '*' were allowed in filenames and even with +these the '*' was allowed only at the end of a pattern and in fact +when used to specify the filename the '*' did not apply to extension. +This gave rise to the all too common expression "*.*". + +REGEX Globber is a SH pattern matcher. This allows such +specifications as *75.zip or * (equivelant to *.* in DOS lingo). +Expressions such as [a-e]*t would fit the name "apple.crt" or +"catspaw.bat" or "elegant". This allows considerably wider +flexibility in file specification, general parsing or any other +circumstance in which this type of pattern matching is wanted. + +A match would mean that the entire string TEXT is used up in matching +the PATTERN and conversely the matched TEXT uses up the entire +PATTERN. + +In the specified pattern string: + `*' matches any sequence of characters (zero or more) + `?' matches any character + `\' suppresses syntactic significance of a special character + [SET] matches any character in the specified set, + [!SET] or [^SET] matches any character not in the specified set. + +A set is composed of characters or ranges; a range looks like +'character hyphen character' (as in 0-9 or A-Z).

Since match() is a call to matche() which +simply has its output mapped to a BOOLEAN value (ie TRUE if pattern +matches or FALSE otherwise), I will concentrate my explanations here +on matche(). + +The purpose of matche() is to match a pattern against a string of +text (usually a file name or specification). The match routine has +extensive pattern validity checking built into it as part of the +parser and allows for a robust pattern match. + +The parser gives an error code on return of type int. The error code +will be one of the the following defined values (defined in match.h): + + MATCH_PATTERN - bad pattern or misformed pattern + MATCH_LITERAL - match failed on character match (standard + character) + MATCH_RANGE - match failure on character range ([..] construct) + MATCH_ABORT - premature end of text string (pattern longer + than text string) + MATCH_END - premature end of pattern string (text longer + than pattern called for) + MATCH_VALID - valid match using pattern + +The functions are declared as follows: + + BOOLEAN match (char *pattern, char *text); + + int matche(register char *pattern, register char *text); + + + +IS_VALID_PATTERN() and IS_PATTERN() +=================================== + +There are two routines for determining properties of a pattern +string. The first, is_pattern(), is designed simply to determine if +some character exists within the text which is consistent with a SH +regular expression (this function returns TRUE if so and FALSE if +not). The second, is_valid_pattern() is designed to check the +validity of a given pattern string (TRUE return if valid, FALSE if +not). By 'validity', I mean well formed or syntactically correct. + +In addition, is_valid_pattern() has as one of it's parameters a +return code for determining the type of error found in the pattern if +one exists. The error codes are as follows and defined in match.h: + + PATTERN_VALID - pattern is well formed + PATTERN_ESC - pattern has invalid literal escape ('\' at end of + pattern) + PATTERN_RANGE - [..] construct has a no end range in a '-' pair + (ie [a-]) + PATTERN_CLOSE - [..] construct has no end bracket (ie [abc-g ) + PATTERN_EMPTY - [..] construct is empty (ie []) + +The functions are declared as follows: + + BOOLEAN is_valid_pattern (char *pattern, int *error_type); + + BOOLEAN is_pattern (char *pattern); diff --git a/reference/C/CONTRIB/SNIP/match.h b/reference/C/CONTRIB/SNIP/match.h new file mode 100755 index 0000000..a2ee6b6 --- /dev/null +++ b/reference/C/CONTRIB/SNIP/match.h @@ -0,0 +1,107 @@ +/* + EPSHeader + + File: match.h + Author: J.

The files as they appear in SNIPPETS have been edited +somewhat to remove compiler dependencies and correct minor discrepancies. + +For those who don't already know, Walter Bright is the author of Datalight +Optimum-C, the original optimizing C compiler for PC's. Through a succession +of sales and acquisitions plus continual improvement by Walter,, his compiler +became Zortech C++ and is now sold as Symantec C++. As such, it is the only +major PC compiler which can claim single authorship. It also compiles faster +than most other compilers and is still a market leader in its optimization +technology. + +Like many other library and ancillary functions unique to Walter's compilers, +the MEM package was originally something he wrote for his own use. As noted +above, he published it only once but it has been included as an unheralded +"freebie" in Walter's compilers for the past several years. Walter was kind +enough to grant permission for its inclusion in SNIPPETS beginning with the +April, '94 release. + + +WHAT IS MEM?: +------------- + +MEM is a set of functions used for debugging C pointers and memory allocation +problems. Quoting Walter, "Symptoms of pointer bugs include: hung machines, +scrambled disks, failures that occur once-in-10,000 iterations, irreprodu- +cible results, and male pattern baldness." After writing MEM for use in +developing his own compiler and tools, he reported that its use reduced +pointer bugs by as much as 75%. MEM is simple to add to existing programs +and adds little or no overhead. + + +USING MEM: +---------- + +Included in the MEM package is TOOLKIT.H, which isolates compiler and +environmental dependencies. It should work as-is for most PC compilers and +the Microsoft compiler for SCO Unix. Other environments may be customized by +writing your own HOST.H file, using the existing definitions in TOOLKIT.H as +examples and modifying the values to match your system. Using these +techniques, the MEM package has been used successfully on Amigas, Macs, +VAXes, and many other non-DOS systems. + +The MEM functions exactly parallel the standard library (plus 1 non-standard) +memory allocation functions. To implement MEM in your program, simply do a +global search-and-replace of the following functions: + + malloc() -> mem_malloc() + calloc() -> mem_calloc() + realloc() -> mem_realloc() + free() -> mem_free() + strdup() -> mem_strdup() + +At the beginning of main(), add the following lines: + + mem_init(); + atexit(mem_term); + +In the header section of each of your C files, add... + +#include "mem.h" + +...to every .C file which calls any of the above functions. + +The final step is to compile and link MEM.C into all programs using the MEM +package. It really is a pretty simple procedure! + +MEM has 2 modes of operation, debugging and non-debugging. Use debugging +mode during program development and then turn debugging off for final +production code. Control of debugging is by defining the MEM_DEBUG macro. +If the macro is defined, debugging is on; if undefined, debugging is off. +The default is non-debugging, in which case the MEM functions become trivial +wrappers for the standard functions, incurring virtually no overhead. + + +WHAT MEM DOES: +-------------- + +1. ISO/ANSI verification: + +When Walter wrote MEM, compiler compliance with ANSI standards was still +quite low. MEM verifies ISO/ANSI compliance for situations such as passing +NULL or size 0 to allocation/reallocation functions. + +2. Logging of all allocations and frees: + +All MEM's functions pass the __FILE__ and __LINE__ arguments. During alloca- +tion, MEM makes an entry into a linked list and stores the file and line +information in the list for whichever allocation or free function is called. + +This linked list is the backbone of MEM. When MEM detects a bug, it tells +you where to look in which file to begin tracking the problem. + +3. Verification of frees: + +Since MEM knows about all allocations, when a pointer is freed, MEM can +verify that the pointer was allocated originally. Additionally, MEM will +only allow a pointer to be freed once. + +Freed data is overwritten with a non-zero known value, flushing such problems +as continuing to reference data after it's been freed. The value written +over the data is selected to maximize the probability of a segment fault or +assertion failure if your application references it after it's been freed. + +MEM obviously can't directly detect "if" instances such as... + + mem_free(p); + if (p) ... + +...but by guaranteeing that `p' points to garbage after being freed, code +like this will hopefully never work and will thus be easier to find. + +4. Detection of pointer over- and under-run: + +Pointer overrun occurs when a program stores data past the end of a buffer, +e.g. + + p = malloc(strlen(s)); /* No space for terminating NUL */ + strcpy(p,s); /* Terminating NUL clobber memory */ + +Pointer underrun occurs when a program stores data before the beginning of a +buffer. This error occurs less often than overruns, but MEM detects it +anyway. MEM does this by allocating a little extra at each end of every +buffer, which is filled with a known value, called a sentinel. MEM detects +overruns and underruns by verifying the sentinel value when the buffer is +freed. + +5. Dependence on values in buffer obtained from malloc(): + +When obtaining a buffer from malloc(), a program may develop erroneous and +creeping dependencies on whatever random (and sometimes repeatable) values +the buffer may contain. The mem_malloc() function prevents this by always +setting the data in a buffer to a known non-zero value before returning its +pointer. This also prevents another common error when running under MS-DOS +which doesn't clear unused memory when loading a program. These bugs are +particularly nasty to find since correct program operation may depend on what +was last run! + +6. Realloc problems: + +Common problems when using realloc() are: 1) depending on realloc() *not* +shifting the location of the buffer in memory, and 2) depending on finding +certain values in the uninitialized region of the realloc'ed buffer. + +MEM flushes these out by *always* moving the buffer and stomping on values +past the initialized area. + +7. Memory leak detection: + +Memory "leaks" are areas that are allocated but never freed. This can become +a major problem in programs that must run for long periods without interrup- +tion (e.g. BBS's). If there are leaks, eventually the program will run out +of memory and fail. + +Another form of memory leak occurs when a piece of allocated memory should +have been added to some central data structure, but wasn't. + +MEM find memory leaks by keeping track of all allocations and frees. When +mem_term() is called, a list of all unfreed allocations is printed along with +the files and line numbers where the allocations occurred. + +8. Pointer checking: + +Sometimes it's useful to be able to verify that a pointer is actually +pointing into free store. MEM provides a function... + + mem_checkptr(void *p); + +...to do this. + +9. Consistency checking: + +Occasionally, even MEM's internal data structures get clobbered by a wild +pointer. When this happens, you can track it down by sprinkling your code +temporarily with calls to mem_check(), which performs a consistency check on +the free store. + +10. Out of memory handling: + +MEM can be set using mem_setexception() (see MEM.H) to handle out-of-memory +conditions in any one of several predefined ways: + + 1. Present an "Out of memory" message and terminate the program. + 2. Abort the program with no message. + 3. Mimic ISO/ANSI and return NULL. + 4. Call a user-specified function, perhaps involving virtual memory + or some other "emergency reserve". + 5. Retry (be careful to avoid infinite loops!) + +11. Companion techniques: + +Since MEM presets allocated and stomps on freed memory, this facilitates +adding your own code to add tags to your data structures when debugging. If +the structures are invalid, you'll know it because MEM will have clobbered +your verification tags. + + +SUMMARY: +-------- + +Since it is, in the final analysis, a software solution, MEM is fallible. As +the saying goes, "Nothing is foolproof because fools are so ingenious." +Walter himself readily acknowledges that there are circumstances where your +code can do sufficient damage to MEM's internal data structures to render it +useless. The good news is such circumstances are few and far between. For +most memory debugging, MEM is a highly reliable and valuable addition to your +C programming toolchest. diff --git a/reference/C/CONTRIB/SNIP/memavail.c b/reference/C/CONTRIB/SNIP/memavail.c new file mode 100755 index 0000000..67400d9 --- /dev/null +++ b/reference/C/CONTRIB/SNIP/memavail.c @@ -0,0 +1,32 @@ +/* +** MEMAVAIL.C - Report available DOS memory +** +** public domain by Thor Johnson +*/ + +#include + +long memavail(void) +{ + union REGS regs; + + /* Request impossibly large number of 16-byte paragraphs from DOS */ + + regs.h.ah = 0x48; + regs.x.bx = 0xFFFF; + + int86(0x21,®s,®s); + + return((long)regs.x.bx * 16L); +} + +#ifdef TEST + +#include + +main() +{ + printf("Available DOS memory = %ld bytes\n", memavail()); +} + +#endif /* TEST */ diff --git a/reference/C/CONTRIB/SNIP/memrev.c b/reference/C/CONTRIB/SNIP/memrev.c new file mode 100755 index 0000000..e94d435 --- /dev/null +++ b/reference/C/CONTRIB/SNIP/memrev.c @@ -0,0 +1,52 @@ +/* +** Public domain demo by Ray Gardner, 7 dec 88 +** +** Here's an old programming trick that (I bet) will be new to at least a +** few of you out there, even some "old hands".

Box 324 + Redwood City, CA 94064 + +================================================================== +CHAPTER 1: What is a pointer? + + One of the things beginners in C find most difficult to +understand is the concept of pointers. The purpose of this +document is to provide an introduction to pointers and their use +to these beginners. + + I have found that often the main reason beginners have a +problem with pointers is that they have a weak or minimal feeling +for variables, (as they are used in C). Thus we start with a +discussion of C variables in general. + + A variable in a program is something with a name, the value +of which can vary. The way the compiler and linker handles this +is that it assigns a specific block of memory within the computer +to hold the value of that variable. The size of that block +depends on the range over which the variable is allowed to vary. +For example, on PC's the size of an integer variable is 2 bytes, +and that of a long integer is 4 bytes. In C the size of a +variable type such as an integer need not be the same on all +types of machines. + + When we declare a variable we inform the compiler of two +things, the name of the variable and the type of the variable. +For example, we declare a variable of type integer with the name +k by writing: + + int k; + + On seeing the "int" part of this statement the compiler sets +aside 2 bytes (on a PC) of memory to hold the value of the +integer. It also sets up a symbol table. And in that table it +adds the symbol k and the address in memory where those 2 bytes +were set aside. + + Thus, later if we write: + + k = 2; + +at run time we expect that the value 2 will be placed in that +memory location reserved for the storage of the value of k. + + In a sense there are two "values" associated with k, one +being the value of the integer stored there (2 in the above +example) and the other being the "value" of the memory location +where it is stored, i.e. the address of k. Some texts refer to +these two values with the nomenclature rvalue (right value, +pronounced "are value") and lvalue (left value, pronunced "el +value") respectively. + + The lvalue is the value permitted on the left side of the +assignment operator '=' (i.e. the address where the result of +evaluation of the right side ends up). The rvalue is that which +is on the right side of the assignment statment, the '2' above. +Note that rvalues cannot be used on the left side of the +assignment statement. Thus: 2 = k; is illegal. + + Okay, now consider: + + int j, k; + k = 2; + j = 7; <-- line 1 + k = j; <-- line 2 + + In the above, the compiler interprets the j in line 1 as the +address of the variable j (its lvalue) and creates code to copy +the value 7 to that address. In line 2, however, the j is +interpreted as its rvalue (since it is on the right hand side of +the assignment operator '='). That is, here the j refers to the +value _stored_ at the memory location set aside for j, in this +case 7. So, the 7 is copied to the address designated by the +lvalue of k. + + In all of these examples, we are using 2 byte integers so all +copying of rvalues from one storage location to the other is done +by copying 2 bytes. Had we been using long integers, we would be +copying 4 bytes. + + Now, let's say that we have a reason for wanting a variable +designed to hold an lvalue (an address). The size required to +hold such a value depends on the system. On older desk top +computers with 64K of memory total, the address of any point in +memory can be contained in 2 bytes. Computers with more memory +would require more bytes to hold an address. Some computers, +such as the IBM PC might require special handling to hold a +segment and offset under certain circumstances. The actual size +required is not too important so long as we have a way of +informing the compiler that what we want to store is an address. + + Such a variable is called a "pointer variable" (for reasons +which will hopefully become clearer a little later). In C when +we define a pointer variable we do so by preceding its name with +an asterisk. In C we also give our pointer a type which, in this +case, refers to the type of data stored at the address we will be +storing in our pointer. For example, consider the variable +definition: + + int *ptr; + + ptr is the _name_ of our variable (just as 'k' was the name +of our integer variable). The '*' informs the compiler that we +want a pointer variable, i.e. to set aside however many bytes is +required to store an address in memory. The "int" says that we +intend to use our pointer variable to store the address of an +integer. Such a pointer is said to "point to" an integer. Note, +however, that when we wrote "int k;" we did not give k a value. +If this definiton was made outside of any function many compilers +will initialize it to zero. Simlarly, ptr has no value, that is +we haven't stored an address in it in the above definition. In +this case, again if the definition is outside of any function, it +is intialized to a value #defined by your compiler as NULL. It +is called a NULL pointer. While in most cases NULL is #defined +as zero, it need not be. That is, different compilers handle +this differently. Also note that while zero is an integer, NULL +need not be. + + But, back to using our new variable ptr. Suppose now that we +want to store in ptr the address of our integer variable k. To +do this we use the unary '&' operator and write: + + ptr = &k; + + What the '&' operator does is retrieve the lvalue (address) +of k, even though k is on the right hand side of the assignment +operator '=', and copies that to the contents of our pointer ptr. +Now, ptr is said to "point to" k. Bear with us now, there is +only one more operator we need to discuss. + + The "dereferencing operator" is the asterisk and it is used +as follows: + + *ptr = 7; + +will copy 7 to the address pointed to by ptr. Thus if ptr +"points to" (contains the address of) k, the above statement will +set the value of k to 7. That is, when we use the '*' this way +we are refering to the value of that which ptr is pointing +at, not the value of the pointer itself. + + Similarly, we could write: + + printf("%d\n",*ptr); + +to print to the screen the integer value stored at the address +pointed to by "ptr". + + One way to see how all this stuff fits together would be to +run the following program and then review the code and the output +carefully. + +------------------------------------------------- +#include <stdio.h> + +int j, k; +int *ptr; + + +int main(void) +{ + j = 1; + k = 2; + ptr = &k; + printf("\n"); + printf("j has the value %d and is stored at %p\n",j,&j); + printf("k has the value %d and is stored at %p\n",k,&k); + printf("ptr has the value %p and is stored at %p\n",ptr,&ptr); + printf("The value of the integer pointed to by ptr is %d\n", + *ptr); + return 0; +} +--------------------------------------- +To review: + + A variable is defined by giving it a type and a name (e.g. + int k;) + + A pointer variable is defined by giving it a type and a name + (e.g. int *ptr) where the asterisk tells the compiler that + the variable named ptr is a pointer variable and the type + tells the compiler what type the pointer is to point to + (integer in this case). + + Once a variable is defined, we can get its address by + preceding its name with the unary '&' operator, as in &k. + + We can "dereference" a pointer, i.e. refer to the value of + that which it points to, by using the unary '*' operator as + in *ptr. + + An "lvalue" of a variable is the value of its address, i.e. + where it is stored in memory. The "rvalue" of a variable is + the value stored in that variable (at that address). + +================================================================== +CHAPTER 2: Pointer types and Arrays + + Okay, let's move on. Let us consider why we need to identify +the "type" of variable that a pointer points to, as in: + + int *ptr; + + One reason for doing this is so that later, once ptr "points +to" something, if we write: + + *ptr = 2; + +the compiler will know how many bytes to copy into that memory +location pointed to by ptr. If ptr was defined as pointing to an +integer, 2 bytes would be copied, if a long, 4 bytes would be +copied. Similarly for floats and doubles the appropriate number +will be copied. But, defining the type that the pointer points +to permits a number of other interesting ways a compiler can +interpret code. For example, consider a block in memory +consisting if ten integers in a row. That is, 20 bytes of memory +are set aside to hold 10 integer. + + Now, let's say we point our integer pointer ptr at the first +of these integers. Furthermore lets say that integer is located +at memory location 100 (decimal). What happens when we write: + + ptr + 1; + + Because the compiler "knows" this is a pointer (i.e. its +value is an address) and that it points to an integer (its +current address, 100, is the address of an integer), it adds 2 to +ptr instead of 1, so the pointer "points to" the _next_ +_integer_, at memory location 102. Similarly, were the ptr +defined as a pointer to a long, it would add 4 to it instead of +1. The same goes for other data types such as floats, doubles, +or even user defined data types such as structures. + + Similarly, since ++ptr and ptr++ are both equivalent to +ptr + 1 (though the point in the program when ptr is incremented +may be different), incrementing a pointer using the unary ++ +operator, either pre- or post-, increments the address it stores +by the amount sizeof(type) (i.e. 2 for an integer, 4 for a long, +etc.). + + Since a block of 10 integers located contiguously in memory +is, by definition, an array of integers, this brings up an +interesting relationship between arrays and pointers. + + Consider the following: + + int my_array[] = {1,23,17,4,-5,100}; + + Here we have an array containing 6 integers. We refer to +each of these integers by means of a subscript to my_array, i.e. +using my_array[0] through my_array[5]. But, we could +alternatively access them via a pointer as follows: + + int *ptr; + + ptr = &my_array[0]; /* point our pointer at the first + integer in our array */ + + And then we could print out our array either using the array +notation or by dereferencing our pointer. The following code +illustrates this: +------------------------------------------------------ +#include <stdio.h> + +int my_array[] = {1,23,17,4,-5,100}; +int *ptr; + +int main(void) +{ + int i; + ptr = &my_array[0]; /* point our pointer to the array */ + printf("\n\n"); + for(i = 0; i < 6; i++) + { + printf("my_array[%d] = %d ",i,my_array[i]); /*<-- A */ + printf("ptr + %d = %d\n",i, *(ptr + i)); /*<-- B */ + } + return 0; +} +---------------------------------------------------- + Compile and run the above program and carefully note lines A +and B and that the program prints out the same values in either +case. Also note how we dereferenced our pointer in line B, i.e. +we first added i to it and then dereferenced the the new pointer. +Change line B to read: + + printf("ptr + %d = %d\n",i, *ptr++); + +and run it again... then change it to: + + printf("ptr + %d = %d\n",i, *(++ptr)); + +and try once more. Each time try and predict the outcome and +carefully look at the actual outcome. + + In C, the standard states that wherever we might use +&var_name[0] we can replace that with var_name, thus in our code +where we wrote: + + ptr = &my_array[0]; + + we can write: + + ptr = my_array; to achieve the same result. + + This leads many texts to state that the name of an array is a +pointer. While this is true, I prefer to mentally think "the +name of the array is a _constant_ pointer". Many beginners +(including myself when I was learning) forget that _constant_ +qualifier. In my opinon this leads to some confusion. For +example, while we can write ptr = my_array; we cannot write + + my_array = ptr; + + The reason is that the while ptr is a variable, my_array is a +constant. That is, the location at which the first element of +my_array will be stored cannot be changed once my_array[] has +been declared. + +Modify the example program above by changing + + ptr = &my_array[0]; to ptr = my_array; + +and run it again to verify the results are identical. + + Now, let's delve a little further into the difference between +the names "ptr" and "my_array" as used above. We said that +my_array is a constant pointer. What do we mean by that? Well, +to understand the term "constant" in this sense, let's go back to +our definition of the term "variable". When we define a variable +we set aside a spot in memory to hold the value of the +appropriate type. Once that is done the name of the variable can +be interpreted in one of two ways. When used on the left side of +the assignment operator, the compiler interprets it as the memory +location to which to move that which lies on the right side of +the assignment operator. But, when used on the right side of the +assignment operator, the name of a variable is interpreted to +mean the contents stored at that memory address set aside to hold +the value of that variable. + + With that in mind, let's now consider the simplest of +constants, as in: + + int i, k; + i = 2; + + Here, while "i" is a variable and then occupies space in the +data portion of memory, "2" is a constant and, as such, instead +of setting aside memory in the data segment, it is imbedded +directly in the code segment of memory. That is, while writing +something like k = i; tells the compiler to create code which at +run time will look at memory location &i to determine the value +to be moved to k, code created by i = 2; simply puts the '2' in +the code and there is no referencing of the data segment. + + Similarly, in the above, since "my_array" is a constant, once +the compiler establishes where the array itself is to be stored, +it "knows" the address of my_array[0] and on seeing: + + ptr = my_array; + +it simply uses this address as a constant in the code segment and +there is no referencing of the data segment beyond that. + + Well, that's a lot of technical stuff to digest and I don't +expect a beginner to understand all of it on first reading. With +time and experimentation you will want to come back and re-read +the first 2 chapters. But for now, let's move on to the +relationship between pointers, character arrays, and strings. + +================================================================== +CHAPTER 3: Pointers and Strings + + The study of strings is useful to further tie in the +relationship between pointers and arrays. It also makes it easy +to illustrate how some of the standard C string functions can be +implemented. Finally it illustrates how and when pointers can and +should be passed to functions. + + In C, strings are arrays of characters. This is not +necessarily true in other languages. In Pascal or (most versions +of) Basic, strings are treated differently from arrays. To start +off our discussion we will write some code which, while preferred +for illustrative purposes, you would probably never write in an +actual program. Consider, for example: + + char my_string[40]; + + my_string[0] = 'T'; + my_string[1] = 'e'; + my_string[2] = 'd': + my_string[3] = '\0'; + + While one would never build a string like this, the end +result is a string in that it is an array of characters +_terminated_with_a_nul_character_. By definition, in C, a string +is an array of characters terminated with the nul character. Note +that "nul" is _not_ the same as "NULL". The nul refers to a zero +as is defined by the escape sequence '\0'. That is it occupies +one byte of memory. The NULL, on the other hand, is the value of +an uninitialized pointer and pointers require more than one byte +of storage. NULL is #defined in a header file in your C +compiler, nul may not be #defined at all. + + Since writing the above code would be very time consuming, C +permits two alternate ways of achieving the same thing. First, +one might write: + + char my_string[40] = {'T', 'e', 'd', '\0',}; + + But this also takes more typing than is convenient. So, C +permits: + + char my_string[40] = "Ted"; + + When the double quotes are used, instead of the single quotes +as was done in the previous examples, the nul character ( '\0' ) +is automatically appended to the end of the string. + + In all of the above cases, the same thing happens. The +compiler sets aside an contiguous block of memory 40 bytes long +to hold characters and initialized it such that the first 4 +characters are Ted\0. + + Now, consider the following program: + +------------------program 3.1------------------------------------- +#include <stdio.h> + +char strA[80] = "A string to be used for demonstration purposes"; +char strB[80]; + +int main(void) +{ + char *pA; /* a pointer to type character */ + char *pB; /* another pointer to type character */ + puts(strA); /* show string A */ + pA = strA; /* point pA at string A */ + puts(pA); /* show what pA is pointing to */ + pB = strB; /* point pB at string B */ + putchar('\n'); /* move down one line on the screen */ + while(*pA != '\0') /* line A (see text) */ + { + *pB++ = *pA++; /* line B (see text) */ + } + *pB = '\0'; /* line C (see text) */ + puts(strB); /* show strB on screen */ + return 0; +} +--------- end program 3.1 ------------------------------------- + + In the above we start out by defining two character arrays of +80 characters each. Since these are globally defined, they are +initialized to all '\0's first. Then, strA has the first 42 +characters initialized to the string in quotes. + + Now, moving into the code, we define two character pointers +and show the string on the screen. We then "point" the ponter pA +at strA. That is, by means of the assignment statement we copy +the address of strA[0] into our variable pA. We now use puts() +to show that which is pointed to by pA on the screen. Consider +here that the function prototype for puts() is: + + int puts(const char *s); + + For the moment, ignore the "const". The parameter passed to +puts is a pointer, that is the _value_ of a pointer (since all +parameters in C are passed by value), and the value of a pointer +is the address to which it points, or, simply, an address. Thus +when we write: + + puts(strA); as we have seen, we are passing the + +address of strA[0]. Similarly, when we write: + + puts(pA); we are passing the same address, since + +we have set pA = strA; + + Given that, follow the code down to the while() statement on +line A. Line A states: + + While the character pointed to by pA (i.e. *pA) is not a nul +character (i.e. the terminating '\0'), do the following: + + line B states: copy the character pointed to by pA to the +space pointed to by pB, then increment pA so it points to the +next character and pB so it points to the next space. + + Note that when we have copied the last character, pA now +points to the terminating nul character and the loop ends. +However, we have not copied the nul character. And, by +definition a string in C _must_ be nul terminated. So, we add +the nul character with line C. + + It is very educational to run this program with your debugger +while watching strA, strB, pA and pB and single stepping through +the program. It is even more educational if instead of simply +defining strB[] as has been done above, initialize it also with +something like: + + strB[80] = "12345678901234567890123456789012345678901234567890" + +where the number of digits used is greater than the length of +strA and then repeat the single stepping procedure while watching +the above variables. Give these things a try! + + Of course, what the above program illustrates is a simple way +of copying a string. After playing with the above until you have +a good understanding of what is happening, we can proceed to +creating our own replacement for the standard strcpy() that comes +with C. It might look like: + + char *my_strcpy(char *destination, char *source) + { + char *p = destination + while (*source != '\0') + { + *p++ = *source++; + } + *p = '\0'; + return destination. + } + + In this case, I have followed the practice used in the +standard routine of returning a pointer to the destination. + + Again, the function is designed to accept the values of two +character pointers, i.e. addresses, and thus in the previous +program we could write: + +int main(void) +{ + my_strcpy(strB, strA); + puts(strB); +} + + I have deviated slightly from the form used in standard C +which would have the prototype: + + char *my_strcpy(char *destination, const char *source); + + Here the "const" modifier is used to assure the user that the +function will not modify the contents pointed to by the source +pointer. You can prove this by modifying the function above, and +its prototype, to include the "const" modifier as shown. Then, +within the function you can add a statement which attempts to +change the contents of that which is pointed to by source, such +as: + + *source = 'X'; + +which would normally change the first character of the string to +an X. The const modifier should cause your compiler to catch +this as an error. Try it and see. + + Now, let's consider some of the things the above examples +have shown us. First off, consider the fact that *ptr++ is to be +interpreted as returning the value pointed to by ptr and then +incrementing the pointer value. On the other hand, note that +this has to do with the precedence of the operators. Were we to +write (*ptr)++ we would increment, not the pointer, but that +which the pointer points to! i.e. if used on the first character +of the above example string the 'T' would be incremented to a +'U'. You can write some simple example code to illustrate this. + + Recall again that a string is nothing more than an array +of characters. What we have done above is deal with copying +an array. It happens to be an array of characters but the +technique could be applied to an array of integers, doubles, +etc. In those cases, however, we would not be dealing with +strings and hence the end of the array would not be +_automatically_ marked with a special value like the nul +character. We could implement a version that relied on a +special value to identify the end. For example, we could +copy an array of postive integers by marking the end with a +negative integer. On the other hand, it is more usual that +when we write a function to copy an array of items other +than strings we pass the function the number of items to be +copied as well as the address of the array, e.g. something +like the following prototype might indicate: + + void int_copy(int *ptrA, int *ptrB, int nbr); + +where nbr is the number of integers to be copied. You might want +to play with this idea and create an array of integers and see if +you can write the function int_copy() and make it work. + + Note that this permits using functions to manipulate very +large arrays. For example, if we have an array of 5000 integers +that we want to manipulate with a function, we need only pass to +that function the address of the array (and any auxiliary +information such as nbr above, depending on what we are doing). +The array itself does _not_ get passed, i.e. the whole array is +not copied and put on the stack before calling the function, only +its address is sent. + + Note that this is different from passing, say an integer, to +a function. When we pass an integer we make a copy of the +integer, i.e. get its value and put it on the stack. Within the +function any manipulation of the value passed can in no way +effect the original integer. But, with arrays and pointers we +can pass the address of the variable and hence manipulate the +values of of the original variables. + +================================================================== +CHAPTER 4: More on Strings + + Well, we have progressed quite aways in a short time! Let's +back up a little and look at what was done in Chapter 3 on +copying of strings but in a different light. Consider the +following function: + + char *my_strcpy(char dest[], char source[]) + { + int i = 0; + + while (source[i] != '\0') + { + dest[i] = source[i]; + i++; + } + dest[i] = '\0'; + return dest; + } + + Recall that strings are arrays of characters. Here we have +chosen to use array notation instead of pointer notation to do +the actual copying. The results are the same, i.e. the string +gets copied using this notation just as accurately as it did +before. This raises some interesting points which we will +discuss. + + Since parameters are passed by value, in both the passing of +a character pointer or the name of the array as above, what +actually gets passed is the address of the first element of each +array. Thus, the numerical value of the parameter passed is the +same whether we use a character pointer or an array name as a +parameter. This would tend to imply that somehow: + + source[i] is the same as *(p+i); + +In fact, this is true, i.e wherever one writes a[i] it can be +replaced with *(a + i) without any problems. In fact, the +compiler will create the same code in either case. Now, looking +at this last expression, part of it.. (a + i) is a simple +addition using the + operator and the rules of c state that such +an expression is commutative. That is (a + i) is identical to +(i + a). Thus we could write *(i + a) just as easily as +*(a + i). + + But *(i + a) could have come from i[a] ! From all of this +comes the curious truth that if: + + char a[20]; + int i; + + writing a[3] = 'x'; is the same as writing + + 3[a] = 'x'; + + Try it! Set up an array of characters, integers or longs, +etc. and assigned the 3rd or 4th element a value using the +conventional approach and then print out that value to be sure +you have that working. Then reverse the array notation as I have +done above. A good compiler will not balk and the results will +be identical. A curiosity... nothing more! + + Now, looking at our function above, when we write: + + dest[i] = source[i]; + + this gets interpreted by C to read: + + *(dest + i) = *(source + i); + + But, this takes 2 additions for each value taken on by i. +Additions, generally speaking, take more time than +incrementations (such as those done using the ++ operator as in +i++). This may not be true in modern optimizing compilers, but +one can never be sure. Thus, the pointer version may be a bit +faster than the array version. + + Another way to speed up the pointer version would be to +change: + + while (*source != '\0') to simply while (*source) + +since the value within the parenthesis will go to zero (FALSE) at +the same time in either case. + + At this point you might want to experiment a bit with writing +some of your own programs using pointers. Manipulating strings +is a good place to experiment. You might want to write your own +versions of such standard functions as: + + strlen(); + strcat(); + strchr(); + +and any others you might have on your system. + + We will come back to strings and their manipulation through +pointers in a future chapter. For now, let's move on and discuss +structures for a bit. + +================================================================== +CHAPTER 5: Pointers and Structures + + As you may know, we can declare the form of a block of data +containing different data types by means of a structure +declaration. For example, a personnel file might contain +structures which look something like: + + struct tag{ + char lname[20]; /* last name */ + char fname[20]; /* first name */ + int age; /* age */ + float rate; /* e.g. 12.75 per hour */ + }; + + Let's say we have an bunch of these structures in a disk file +and we want to read each one out and print out the first and last +name of each one so that we can have a list of the people in our +files. The remaining information will not be printed out. We +will want to do this printing with a function call and pass to +that function a pointer to the structure at hand. For +demonstration purposes I will use only one structure for now. But +realize the goal is the writing of the function, not the reading +of the file which, presumably, we know how to do. + + For review, recall that we can access structure members with +the dot operator as in: + +--------------- program 5.1 ------------------ +#include <stdio.h> +#include <string.h> + +struct tag{ + char lname[20]; /* last name */ + char fname[20]; /* first name */ + int age; /* age */ + float rate; /* e.g. 12.75 per hour */ + }; + +struct tag my_struct; /* declare the structure m_struct */ + +int main(void) +{ + strcpy(my_struct.lname,"Jensen"); + strcpy(my_struct.fname,"Ted"); + printf("\n%s ",my_struct.fname); + printf("%s\n",my_struct.lname); + return 0; +} +-------------- end of program 5.1 -------------- + + Now, this particular structure is rather small compared to +many used in C programs. To the above we might want to add: + + date_of_hire; + date_of_last_raise; + last_percent_increase; + emergency_phone; + medical_plan; + Social_S_Nbr; + etc..... + + Now, if we have a large number of employees, what we want to +do manipulate the data in these structures by means of functions. +For example we might want a function print out the name of any +structure passed to it. However, in the original C (Kernighan & +Ritchie) it was not possible to pass a structure, only a pointer +to a structure could be passed. In ANSI C, it is now permissible +to pass the complete structure. But, since our goal here is to +learn more about pointers, we won't pursue that. + + Anyway, if we pass the whole structure it means there must be +enough room on the stack to hold it. With large structures this +could prove to be a problem. However, passing a pointer uses a +minimum amount of stack space. + + In any case, since this is a discussion of pointers, we will +discuss how we go about passing a pointer to a structure and then +using it within the function. + + Consider the case described, i.e. we want a function that +will accept as a parameter a pointer to a structure and from +within that function we want to access members of the structure. +For example we want to print out the name of the employee in our +example structure. + + Okay, so we know that our pointer is going to point to a +structure declared using struct tag. We define such a pointer +with the definition: + + struct tag *st_ptr; + +and we point it to our example structure with: + + st_ptr = &my_struct; + + Now, we can access a given member by de-referencing the +pointer. But, how do we de-reference the pointer to a structure? +Well, consider the fact that we might want to use the pointer to +set the age of the employee. We would write: + + (*st_ptr).age = 63; + + Look at this carefully. It says, replace that within the +parenthesis with that which st_ptr points to, which is the +structure my_struct. Thus, this breaks down to the same as +my_struct.age. + + However, this is a fairly often used expression and the +designers of C have created an alternate syntax with the same +meaning which is: + + st_ptr->age = 63; + + With that in mind, look at the following program: + +------------ program 5.2 -------------- + +#include <stdio.h> +#include <string.h> + +struct tag{ /* the structure type */ + char lname[20]; /* last name */ + char fname[20]; /* first name */ + int age; /* age */ + float rate; /* e.g. 12.75 per hour */ + }; + +struct tag my_struct; /* define the structure */ + +void show_name(struct tag *p); /* function prototype */ + +int main(void) +{ + struct tag *st_ptr; /* a pointer to a structure */ + st_ptr = &my_struct; /* point the pointer to my_struct */ + strcpy(my_struct.lname,"Jensen"); + strcpy(my_struct.fname,"Ted"); + printf("\n%s ",my_struct.fname); + printf("%s\n",my_struct.lname); + my_struct.age = 63; + show_name(st_ptr); /* pass the pointer */ + return 0; +} + + +void show_name(struct tag *p) +{ + printf("\n%s ", p->fname); /* p points to a structure */ + printf("%s ", p->lname); + printf("%d\n", p->age); +} +-------------------- end of program 5.2 ---------------- + + Again, this is a lot of information to absorb at one time. +The reader should compile and run the various code snippets and +using a debugger monitor things like my_struct and p while single +stepping through the main and following the code down into the +function to see what is happening. + +================================================================== +CHAPTER 6: Some more on Strings, and Arrays of Strings + + Well, let's go back to strings for a bit. In the following +all assignments are to be understood as being global, i.e. made +outside of any function, including main. + + We pointed out in an earlier chapter that we could write: + + char my_string[40] = "Ted"; + +which would allocate space for a 40 byte array and put the string +in the first 4 bytes (three for the characters in the quotes and +a 4th to handle the terminating '\0'. + + Actually, if all we wanted to do was store the name "Ted" we +could write: + + char my_name[] = "Ted"; + +and the compiler would count the characters, leave room for the +nul character and store the total of the four characters in memory +the location of which would be returned by the array name, in this +case my_string. + + In some code, instead of the above, you might see: + + char *my_name = "Ted"; + +which is an alternate approach. Is there a difference between +these? The answer is.. yes. Using the array notation 4 bytes of +storage in the static memory block are taken up, one for each +character and one for the nul character. But, in the pointer +notation the same 4 bytes required, _plus_ N bytes to store the +pointer variable my_name (where N depends on the system but is +usually a minimum of 2 bytes and can be 4 or more). + + In the array notation, my_name is a constant (not a +variable). In the pointer notation my_name is a variable. As to +which is the _better_ method, that depends on what you are going +to do within the rest of the program. + + Let's now go one step further and consider what happens if +each of these definitions are done within a function as opposed +to globally outside the bounds of any function. + +void my_function_A(char *ptr) +{ + char a[] = "ABCDE"; + . + . +} + +void my_function_B(char *ptr) +{ + char *cp = "ABCDE"; + . + . +} + + Here we are dealing with automatic variables in both cases. +In my_function_A the automatic variable is the character array +a[]. In my_function_B it is the pointer cp. While C is designed +in such a way that a stack is not required on those processors +which don't use them, my particular processor (80286) has a +stack. I wrote a simple program incorporating functions similar +to those above and found that in my_function_A the 5 characters +in the string were all stored on the stack. On the other hand, +in my_function_B, the 5 characters were stored in the data space +and the pointer was stored on the stack. + + By making a[] static I could force the compiler to place the +5 characters in the data space as opposed to the stack. I did +this exercise to point out just one more difference between +dealing with arrays and dealing with pointers. By the way, array +initialization of automatic variables as I have done in +my_function_A was illegal in the older K&R C and only "came of +age" in the newer ANSI C. A fact that may be important when one +is considering portabilty and backwards compatability. + + As long as we are discussing the relationship/differences +between pointers and arrays, let's move on to multi-dimensional +arrays. Consider, for example the array: + + char multi[5][10]; + + Just what does this mean? Well, let's consider it in the +following light. + + char multi[5][10]; + ^^^^^^^^^^^^^ + + If we take the first, underlined, part above and consider it +to be a variable in its own right, we have an array of 10 +characters with the "name" multi[5]. But this name, in itself, +implies an array of 5 somethings. In fact, it means an array of +five 10 character arrays. Hence we have an array of arrays. In +memory we might think of this as looking like: + + multi[0] = "0123456789" + multi[1] = "abcdefghij" + multi[2] = "ABCDEFGHIJ" + multi[3] = "9876543210" + multi[4] = "JIHGFEDCBA" + +with individual elements being, for example: + + multi[0][3] = '3' + multi[1][7] = 'h' + multi[4][0] = 'J' + + Since arrays are to be contiguous, our actual memory block +for the above should look like: + + "0123456789abcdefghijABCDEFGHIJ9876543210JIHGFEDCBA" + + Now, the compiler knows how many columns are present in the +array so it can interpret multi + 1 as the address of the 'a' in +the 2nd row above. That is, it adds 10, the number of columns, +to get this location. If we were dealing with integers and an +array with the same dimension the compiler would add +10*sizeof(int) which, on my machine, would be 20. Thus, the +address of the "9" in the 4th row above would be &multi[3][0] or +*(multi + 3) in pointer notation. To get to the content of the +2nd element in row 3 we add 1 to this address and dereference the +result as in + + *(*(multi + 3) + 1) + + With a little thought we can see that: + + *(*(multi + row) + col) and + multi[row][col] yield the same results. + + The following program illustrates this using integer arrays +instead of character arrays. + +------------------- program 6.1 ---------------------- +#include <stdio.h> + +#define ROWS 5 +#define COLS 10 + +int multi[ROWS][COLS]; + +int main(void) +{ + int row, col; + for (row = 0; row < ROWS; row++) + for(col = 0; col < COLS; col++) + multi[row][col] = row*col; + for (row = 0; row < ROWS; row++) + for(col = 0; col < COLS; col++) + { + printf("\n%d ",multi[row][col]); + printf("%d ",*(*(multi + row) + col)); + } + return 0; +} +----------------- end of program 6.1 --------------------- + + Because of the double de-referencing required in the pointer +version, the name of a 2 dimensional array is said to be a +pointer to a pointer. With a three dimensional array we would be +dealing with an array of arrays of arrays and a pointer to a +pointer to a pointer. Note, however, that here we have initially +set aside the block of memory for the array by defining it using +array notation. Hence, we are dealing with an constant, not a +variable. That is we are talking about a fixed pointer not a +variable pointer. The dereferencing function used above permits +us to access any element in the array of arrays without the need +of changing the value of that pointer (the address of multi[0][0] +as given by the symbol "multi"). + +EPILOG: + + I have written the preceding material to provide an +introduction to pointers for newcomers to C. In C, the more one +understands about pointers the greater flexibility one has in the +writing of code. The above has just scratched the surface of the +subject. In time I hope to expand on this material. Therefore, +if you have questions, comments, criticisms, etc. concerning that +which has been presented, I would greatly appreciate your +contacting me using one of the mail addresses cited in the +Introduction. + +Ted Jensen diff --git a/reference/C/CONTRIB/SNIP/pushdir.c b/reference/C/CONTRIB/SNIP/pushdir.c new file mode 100755 index 0000000..362922c --- /dev/null +++ b/reference/C/CONTRIB/SNIP/pushdir.c @@ -0,0 +1,192 @@ +/* +** PushDir() and PopDir() +** +** Original Copyright 1988-1991 by Bob Stout as part of +** the MicroFirm Function Library (MFL) +** +** This subset version is an expanded version of the one +** originally published by the author in Tech Specialist +** magazine and is hereby donated to the public domain. +*/ + +#include <dos.h> +#include <stdlib.h> +#include <string.h> +#include <ctype.h> + +#ifdef __TURBOC__ + #include <dir.h> +#else + #include <direct.h> +#endif + +#define DIR_STACK_SIZE 8 +#define MAX_FLEN 67 + +typedef enum {ERROR = -1, FALSE, TRUE} LOGICAL;

For those of +you who already know this or don't care, quit now (this is a little +long). + +The "right-left" rule is a completely regular rule for deciphering C +declarations. It can also be useful in creating them. + +First, symbols. Read + + * as "pointer to" + [] as "array of" + () as "function returning" + +as you encounter them in the declaration. + +STEP 1 +------ +Find the identifier. This is your starting point. Then say to yourself, +"identifier is". You've started your declaration. + +STEP 2 +------ +Look at the symbols on the right of the identifier. If, say, you find "()" +there, then you know that this is the declaration for a function. So you +would then have "identifier is function returning". Or if you found a +"[]" there, you would say "identifier is array of". Continue right until +you run out of symbols *OR* hit a *right* parenthesis ")". (If you hit a +left parenthesis, that's the beginning of a () symbol, even if there +is stuff in between the parentheses. More on that below.) + +STEP 3 +------ +Look at the symbols to the left of the identifier. If it is not one of our +symbols above (say, something like "int"), just say it. Otherwise, translate +it into English using that table above. Keep going left until you run out of +symbols *OR* hit a *left* parenthesis "(". + +Now repeat steps 2 and 3 until you've formed your declaration. Here are some +examples: + + int *p[]; + +1) Find identifier. int *p[]; + ^ + "p is" + +2) Move right until out of symbols or left parenthesis hit. + int *p[]; + ^^ + "p is array of" + +3) Can't move right anymore (out of symbols), so move left and find: + int *p[]; + ^ + "p is array of pointer to" + +4) Keep going left and find: + int *p[]; + ^^^ + "p is array of pointer to int". + +Another example: + + int *(*func())(); + +1) Find the identifier. int *(*func())(); + ^^^^ + "func is" + +2) Move right. int *(*func())(); + ^^ + "func is function returning" + +3) Can't move right anymore because of the right parenthesis, so move left. + int *(*func())(); + ^ + "func is function returning pointer to" + +4) Can't move left anymore because of the left parenthesis, so keep going + right. int *(*func())(); + ^^ + "func is function returning pointer to function returning" + +5) Can't move right anymore because we're out of symbols, so go left. + int *(*func())(); + ^ + "func is function returning pointer to function returning pointer to" + +6) And finally, keep going left, because there's nothing left on the right. + int *(*func())(); + ^^^ + "func is function returning pointer to function returning pointer to int". + +As you can see, this rule can be quite useful. You can also use it to +sanity check yourself while you are creating declarations, and to give +you a hint about where the put the next symbol and whether parentheses +are required. + +Some declarations look much more complicated than they are due to array +sizes and argument lists in prototype form. If you see "[3]", that's +read as "array (size 3) of...". If you see "(char *,int)" that's read +as "function expecting (char *,int) and returning...". Here's a fun +one: + + int (*(*fun_one)(char *,double))[9][20]; + +I won't go through each of the steps to decipher this one. It's: + + "fun_one is pointer to function expecting (char *,double) and + returning pointer to array (size 9) of array (size 20) of int." + +As you can see, it's not as complicated if you get rid of the array sizes +and argument lists: + + int (*(*fun_one)())[][]; + +You can decipher it that way, and then put in the array sizes and argument +lists later. + +Some final words: + +It is quite possible to make illegal declarations using this rule, +so some knowledge of what's legal in C is necessary. For instance, +if the above had been: + + int *((*fun_one)())[][]; + +it would have been "fun_one is pointer to function returning array of array of + ^^^^^^^^^^^^^^^^^^^^^^^^ +pointer to int".

Next - it opens the program itself (the +.EXE file) by using "argv[0]", which points to the actual program name +complete with the path under DOS 3.0 or later. It then attempts to lock +the first 500 bytes of the program on disk, and if successful (i.e. return +!= -1) it unlocks the same bytes and closes the file (actually - the unlock +is superfluous, since closing the file releases all locks) and returns the +"TRUE" result. If it fails - it closes the .EXE file and returns FALSE. +Note that this does not depend on opening a file in shared mode to test it. + +Note that this code must be modified slightly to be useful for MicroSoft +C, since they use the "locking" procedure for both lock & unlock. You +also have to "rewind" before the unlock, since M/S C works from the +current file-pointer forward.

As before it +is named "SNIPdddd.xxx", where "dddd" is the release date and "xxx" is the +archive utility extension. For example, I distribute the Apr '94 edition as +SNIP9404.LZH, using the LHA.EXE archive utility. + +New to the Dec '92 release was SNIPDIFF, an archive containing both files and +a utility to create a complete and fully-validated SNIPPETS archive using +files from the last edition of SNIPPETS which haven't changed. This +represents a considerable saving in the size of the archive and, +consequently, the time required to download it from bulletin boards and +public information services. + +Beginning the Apr '93 release, SNIPDIFF became even smaller with the +inclusion of DSAPP.EXE which allows that only the differences for changed +files need be included. DSAPP.EXE is a public domain utility for applying +changes, written by David Burton, and which is distributed with his excellent +TLIB revision control system. diff --git

+ +A: This is perhaps the commonest of Frequently Asked Questions (FAQ's), +especially by beginning C'er. The honest answer is that there is no "best" +compiler and what may be best for you depends to a large degree on what +you'll be using it for. The PC C/C++ compiler market is quite brutal and the +companies that have survived have done so because some number of people think +each of them makes the "best" compiler. + + With the preceding caveat in mind, following are some summaries of the +current crop of C/C++ compilers with some of their strengths and weaknesses. +Additional recommended reading are the C/C++ compiler reviews appearing in PC +Magazine. PC Mag's reviews for many years were highly slanted and suspect, +but in the past 2 years, have become commendably objective and even-handed. + + +MIX POWER C +----------- + +Power C is the least expensive PC C compiler on the market. The compiler +itself is $20, and an additional $30 will buy their source-level debugger +along with the complete library source code with an assembler. + +So, what's the catch? + +None, actually. Power C is a quite decent and ANSI-conforming compiler which +compiles relatively tight, fast code relatively quickly. It's biggest +drawback is its use of a non-standard object file format which obviates +object-level compatibility with any other compiler using Microsoft/Intel +standard object file formats. Another problem is lack of support from 3rd +party library vendors. Although Mix sells a wide range of libraries +themselves, it's difficult to convince a vendor to produce a $100 add-on +library for a $20 compiler. + +On the plus side, Power C comes with the best user's manual for students in +the business. The beginner's tutorial section has enabled many beginning C +programmers to get up to speed without spending another dime on any other +textbooks. Should you want more instruction, Mix sells a package including +Power C with the library source and debugger along with the book "Master C" +for only $60. + +Power C's primary technical claim to fame is its floating point which +challenges the industry leader, Watcom, in many cases. It's also the only +remaining C compiler which can run effectively on small or older machines +without extended memory (SC++ can also, but is limited to *very* small +programs). + + + +MICROSOFT VISUAL C++ (VC++) +--------------------------- + +Microsoft's professional compiler now comes in two versions with the same +name. The profession version replaces Microsoft C/C++, version 7.0. The +regular version replaces Microsoft Quick C for Windows. The primary +difference is the price and the extras since each requires at least a 386 +processor, 4 Mb of *available* extended memory, and a DPMI server such as +Windows 3.1. If you don't have the machine resources, you can't use VC++. + +On the plus side, VC++ is an excellent C++ compiler and generates executables +which may not always be smaller than Borland, but usually execute faster. +Microsoft's C compilers are still the standard for PC C compilers and it +shows in the ready availability of 3rd party libraries supporting it. Support +for Windows programming is excellent with tools only rivaled by SC++ (which is +shipped with licensed copies of VC++'s MFC 2.0 class library). + +Compile times with full optimization are still quite sluggish, but using the +quick compile option can be provide acceptable results. + + +BORLAND C++ (BC++) +------------------ + +BC++ carries on Borland's tradition of providing excellent bang for the buck. +The latest release (3.1) of their professional compiler is an attractive +alternative to shops also considering VC++. BC++ isn't as demanding as VC++ +and only requires a 286 and 2 Mb of *available* extended memory to run. A full +32-bit version is currently available for OS/2 2.1. Windows programming +support is also quite good, but has been leapfrogged somewhat by VC++ and SC++ +for the time being. + +Borland's tools are uniformly excellent, but the compiler still suffers a bit +in comparison to the industry's technological leaders, Microsoft, Watcom, and +Symantec - although the gap is closing. As with VC++, it's an excellent C++ +compiler and enjoys widespread support among 3rd party library vendors. Like +all Borland compilers, ease of use was a design priority, all oriented to the +excellent IDE. + +Borland recently alienated many of their loyal customers with the release of +BC++ 4.0. In addition to the normal version x.0 bugs that we all expect, the +new version came with no DOS IDE, vastly slower compilation times (with no +apparent increase in optimization to justify the slowdown), and an odious new +license agreement that their lawyers quickly rescinded in the face of the +massive desertion of corporate clients. They're working hard to get folks to +like them again, but for the first time in their corporate life, they have +seriously dissatisfied customers and aren't quite sure how to handle it. + + +TURBO C++ (TC++) +---------------- + +TC++ is to Borland's C++ compiler targeted at the hobbyist market. The latest +version (TC++ 3.1) raised quite a stir when Borland released it requiring at +least a 286 processor and 1 Mb of *available* extended memory above the +normal 640K DOS limit. Many hobbyists running on older XT's, or machines +without the excess memory capacity have therefore failed to upgrade to the +new release. + +If you have the machine to support it, TC++ has the usual Borland attributes +of extreme ease-of-use, attractive Integrated Development Environment (IDE), +and good supporting tools. Based on the facts of BC++ 4.0 cited above, it has +become the compiler of choice for many Borland loyalists. + + +SYMANTEC C++ (SC++) +------------------- + +Symantec C++ (nee Zortech C++) was the industry's first C++ compiler, but fell +behind in tracking the C++ language spec. Bought out by Symantec in 1991, the +C compiler was always excellent and now its C++ compiler rates among the best. + +SC++ supports DOS, Mac, Unix, Win32s, and NT (OS/2 was supported in previous +Zortech releases and may be again) using an extremely powerful new object- +oriented Windows-hosted IDE. It includes excellent libraries and add-ons +including a TSR library, swapping spawn functions, a royalty-free 32-bit DOS +extender, and an excellent set of ancillary C and C++ tools libraries +including MFC 2.0 as previously noted. VC++ can generate true 32-bit code and +has a switch for generating Pentium code. At the same time that Symantec +bought Zortech, they also bought Multiscope, whose debuggers are included in +the package. As with VC++, SC++ includes excellent tools for quickly +developing Windows applications. + +SC++ has always been in the forefront of optimizer technology along with +Microsoft and Watcom. A major feature is full IEEE-754 and NCEG (Numerical C +Extensions Group (an ANSI working committee trying to make C a suitable +replacement for FORTRAN) compatibilty. + +The only negative for the current release is a poor reputation which arose +largely during the period following the Symantec acquisition of Zortech. With +6.1, these now appear mostly fixed. With the 6.1 release, support of DOS +graphics has been dropped, but an updated version of the excellent Flash +Graphics package shipped with the Zortech versions is available from FlashTek, +which also supplies improved verions of the 32-bit DOS extender and the +pre-Symantec debugger. + +One caveat - if you got the 6.0 release, be sure to get the free 6.1 update! + + +WATCOM C/C++ (WC++) +------------------- + +Watcom is the technological industry leader, performing feats of optimization +and floating point speed other vendors only dream of. The cost is compile +speed, which has been described (somewhat unfairly) as glacial. For all its +technical excellence, WC++ is still a niche market compiler like SC++. As +such, it's 3rd party support is poor, but many have found that Microsoft C +libraries will work just fine with WC++. Like SC++, and unlike BC++ and VC++, +WC++ provides documented support for embedded systems work, although not to +nearly the same degree as Metaware (see below). + +Also, like SC++, WC++ supports 32-bit code generation. WC++ is the compiler +of choice for many OEMs, such as Novell, who want only the best supporting +code for their products. MSC/VC++ compatibility is excellent, but watch out +for Watcom's sensitivity to proper _cdecl declarations, implemented in Watcom +via a pragma rather than as a built-in language feature. Watcom sells both +16- and 32-bit versions of its C/C++ compiler. The best deal is to buy the +32-bit compiler and then purchase the 16-bit upgrade pack. + +Where Watcom really shines is its support for a multitude of environments +with the same compiler(s). Supported are DOS, Win3.1, Win32s, NT, OS/2 (1.x & +2.x), Netware 386, AutoCAD ADS, QNX, Phar Lap and Rational DOS extenders. +With such a bewildering array of targets, compilation is relatively +straightforward but the linker has a steep learning curve. + +Watcom remains the only one of the "big name" compilers to not ofer an IDE, +if that's important to you or you don't own a "real" programmer's editor. + + +METAWARE HIGH-C/C++ (HC++) +-------------------------- + +HC++ is the darling of some segments of the embedded systems market. As such, +it's a lot like WC++, only not quite as good and a lot weirder since it +offers detailed control over every aspect of the executable. Most WC++ +comments apply, except for the ones relating to quality of generated code. +HC++'s code is quite good, but seems to be showing its niche market +orientation (any one remember Manx Aztec C?) + + +TOPSPEED C/C++ (TSC++) +---------------------- + +TSC++ has had a rocky life, getting off to a late start in the market and +never having really quite caught on. Originally, TSC++ was a Turbo C clone +which shared tools and environments with its sister Modula-2 compiler. More +recent versions have extended this by using a modular approach with an +environment supporting "plug-in" compilers for various languages which can +all be used together. The company was recently acquired by Clarion. + +TSC++'s undisputed biggest strength is its smart linker and various features +added to facilitate mixed-language programming (Modula-2, for example, +supports multi-threaded code). Using this technology, you can count on TSC++ +to almost always produce the smallest executables for a given piece of source +code. The library, written almost exclusively in assembly, is also excellent +and contributes to the frugal use of run-time memory. Unfortunately, +compiler-generated code is typically not of the same quality. + +Drawbacks include almost non-existant 3rd party support and the pervasive IDE +which feels more at home to Modula-2 programmers than C programmers. + + +GNU C/C++ (GCC, G++) +-------------------- + +Available from the Free Software Foundation, GCC and G++ are the only +compilers listed here available for free without a guilty conscience. +Originally written for Unix systems, there are several DOS ports available, +all of which require some sort of DOS extender technology built-in in order +to work in DOS's limited memory. OS/2 ports obviously don't share this +limitation. Along with SC++, WC++, and HC++, the gnu compilers round out the +list of full ISO/ANSI/ARM compilers with explicit support for embedded +systems. + +Performance is decent, but not earth-shattering, and executable tends to +exhibit lots of bloat. If you plan to use one of these to write commercial +code, be sure and read the license agreement *very* closely. + + +DUNFIELD MICRO-C +---------------- + +There have been many "small" or "tiny" C's over the years, some useful for +teaching the rudiments of compiler construction, others not much use for +anything. Small C's typically lack structs, unions, bit fields, and even long +integers. + +Why bother listing this one then? + +First of all, Micro-C is an evolving product which, as of version 3, now +includes many features such as structs and unions not normally associated +with small C's. + +Also, the source code (available when you register the shareware version) is +quite decent and really can teach you something about compiler internals. But +Micro-C is genuinely useful for a lot more reasons. + +The author also produces cross-assemblers for a variety of microprocessors +and provides plug-in code generators for his C compiler to use with those +chips as well. The 80x86 version comes ready to compile either PC or embedded +code. Included in the PC library are support for writing TSR's, interrupt- +driven serial I/O, and screen windowing. Amazingly, it also sports an +optimizer, but requires MASM or equivalent for compiling PC applications. + +Supporting small and tiny model only, Micro-C executables are phenomenally +small. "Hello world" programs that run 5-6K on other compilers run under 600 +bytes when compiled with Micro-C. + +One other point needs to be mentioned with respect to Micro-C... Although it +is *a* small C, it has no code commonality with *the* Small C from the book +of the same name. This is important since there are a number of variants of +Small C available, all not much better than the original. Micro-C, OTOH, was +written by Dave Dunfield completely from scratch and is a *much* better +designed piece of code and certainly much more instructive to fledgling +compiler writers. His better design is evinced in code quality and execution +speed. + + +PCC +--- + +The Personal C Compiler is available as shareware. It used to be marketed as +the deSmet C compiler and had a generally good reputation for quick compile +times and tight code. Unfortunately, the product hasn't been seriously +upgraded in quite a while and can't stand too much comparison. It's horribly +non-ANSI compliant, has a weaker set of library functions than Micro-C, +features non-standard file formats, and is generally incompatible with most +published C code + +If price is your concern, Mix Power C costs less to buy than PCC and offers +better performance along with the ANSI compliance that PCC lacks. If you plan +on using an unregistered copy, Gnu C/C++ are vastly superior and are legally +free. If you're attracted to its tight, fast code and can live with quirks +and without ANSI compliance, go with Dunfield Micro-C. diff --git a/reference/C/CONTRIB/SNIP/whicharc.c b/reference/C/CONTRIB/SNIP/whicharc.c new file mode 100755 index 0000000..8ca8ce8 --- /dev/null +++ b/reference/C/CONTRIB/SNIP/whicharc.c @@ -0,0 +1,251 @@ +#include <stdio.h> +#include <string.h> + +/* -------------------------------------------------------------------- + Module: WHICHARC.C + Subject: tries to determine the archiver used to compress files + Author: Heinz Ozwirk & David Gersic + modified for SNIPPETS by Bob Stout + Status: public domain + Started: 28.09.1991 13:35:57 + Modified: 13.10.1991 14:15:57 + Modified: 5 January, 1992 11:50am by David Gersic + Added return codes for self extracting archive files. + Modified: 16 January, 1992, 4:15pm by David Gersic + Added Pak and ARC ver. 6 with information from Richard + Vanhouten @1:272/38.

+ +Here is a quick summary of each function, they are listed in the order in +which you may want to execute them. + +

  • opendir Open a directory stream. +
  • readdir read the current entry in the stream. +
  • scandir Find an entry in a direcory. +
  • seekdir Jump to a directory offset. +
  • telldir Return the current location within the directory stream. +
  • rewinddir Return to the start of the directory stream. +
  • closedir Close a directory. + + +
    + + + + + +

+
+	     off_t telldir(DIR *dir);
+
+	     void rewinddir(DIR *dir);
+
+	     int closedir(DIR *dir);
+
    +
    + +The dirent structure does not seem to be documented in the man pages, +so here it is. +

    + + + + +

    +

    + + + + +
    +
    +
+    %d %i     Decimal signed integer.
+    %o	      Octal integer.

+              No argument expected.
+    %%	      %. No argument expected.
+
+
    +
    +
    +

    + +These identifiers actually have upto 6 parts as shown in the table below. +They MUST be used in the order shown. +

    + +

    + + + + + + + + + + + + + + + + +
    %FlagsMinimum field widthPeriodPrecision. Maximum field widthArgument type
    RequiredOptionalOptionalOptionalOptionalRequired
    +
    +

    + + +

    +

    %

    +The % marks the start and therfore is manatory. +

    + + +

    +

    Flags

    +The format identifers can be altered from their default function by +applying the following flags: +

    + +

    + + + + +
    +
    +
+   -      Left justify.
+   0  	  Field is padded with 0's instead of blanks.
+   +	  Sign of number always O/P.
+   blank  Positive values begin with a blank.
+   # 	  Various uses:
+	  %#o (Octal) 0 prefix inserted.
+	  %#x (Hex)   0x prefix added to non-zero values.
+	  %#X (Hex)   0X prefix added to non-zero values.
+	  %#e         Always show the decimal point.
+	  %#E         Always show the decimal point.
+	  %#f         Always show the decimal point.
+	  %#g         Always show the decimal point trailing 
+	  	      zeros not removed.
+	  %#G         Always show the decimal point trailing
+		      zeros not removed.
+          
+
    +
    +
    + +     +Here are a few more examples. +

    + +

    + + + + +
    +
    +
+    printf(" %-10d \n", number);
+    printf(" %010d \n", number);
+    printf(" %-#10x \n", number);  
+    printf(" %#x \n", number);
+
    +
    +
    + +

    + +

    +

    Minimum field width.

    +By default the width of a field will be the minimum required to hold +the data. If you want to increase the field width you can use the +following syntax. +

    +

    + + + + +
    +
    +
+  main()
+  {
+      int number    =  5;
+      char *pointer = "little";
+
+      printf("Here is a number-%4d-and a-%10s-word.\n", number, pointer);
+  }
+  
+  /*********************************
+   *
+   *	Program result is:
+   *
+   * 	Here is a number-   5-and a-    little-word.
+   *
+   *********************************/
+
    +
    +
    +

    +As you can see, the data is right justified within the field. It can +be left justified by using the - flag. +A maximum string width can also be specified. +

    +The width can also be given as a variable as shown below. +

    +

    + + + + +
    +
    +
+    main()
+    {
+        int number=5;
+
+        printf("---%*d----\n", 6, number);
+    }
+  
+    /*********************************
+     *
+     *    Program result is:
+     *
+     *    ----     5---
+     *
+     *********************************/
+
    +
    +
    +

    +The * is replaced with the supplied int to provide the ability to +dynamically specify the field width. +

    +

    + +

    Period

    +If you wish to specify the     precision of an argument, +it MUST be prefixed with the period. +

    + +

    +

    Precision

    + +The Precision takes different meanings for the different format types. + +

    Float Precision

    +
    +	%8.2f
+
    +This says you require a total field of 8 characters, within the 8 +characters the last 2 will hold the decimal part. + +
    +	%.2f
+
    + +The example above requests the minimum field width and the last two +characters are to hold the decimal part. + +

    Character String Maximum field width

    + +The precision within a string format specifies the maximum +field width. +
    +	%4.8s
+
    +Specifies a minimum width of 4 and a maximum width +of 8 characters. If the string is greater than 8 characters, +it will be cropped down to size. +

    + +Here is a little program +that shows an alternative to strncpy. + +

    * Precision

    + +As with the 'width' above, the precision does not have to be hard +coded, the * symbol can be used and an integer supplied to give its +value. +

    +

    + +

    Format Identifiers

    +The format identifier describes the expected data. The identifier is the +character that ends +Here is a list of the format identifers as used in 'printf' ,'sprintf' +,'fprintf' and 'scanf'. + +
      +
    1. Except for '%' and 'n', all the identifiers expect to extract an argument +from the printf parameter list. +
    2. All of the parmameters should be the value +to be inserted. EXCEPT %s, this expects a +pointer to be passed. +
    +

    An example.

    +

    +

    + + + + +
    +
    +
+	main()
+        {
+            int number=5;
+	    char *pointer="little";
+
+	    printf("Here is a number %d and a %s word.\n", number, pointer);
+	}

    +The problem with this function is that the characters are buffered until +RETURN is hit! This means that getchar does not see the characters +until the user presses return. The non standard function getche +gets around this problem and sees each character as it is pressed. +I have not been able to produce the same function on Linux. +The nearest I can get is by using 'curses' but it keeps clearing the screen! + +

        malloc function

        +
        +
        +malloc (memory allocation) is used to dynamically allocate memory +at run time. Possible uses for this function are: + +
          +
        • Read records of an unknown length. +
        • Read an unknown number of database records. +
        • Link lists. +
        + +The simplest way to reserve memory is to code something like: +

        + + + + +
        +
        +
+	main()
+        {
+            char string[1000];
+
+            strcpy (string, "Some text");
+        }
+
        +
        +

        +The example above has two problems: +

          +
        • If the data is less than + +1000 bytes we are wasting memory. +
        • If the data is greater than 1000 bytes the program is going to crash. +
        • The 1000 bytes are reserved throught out the life of the program. +If this was a long running program that rarely used the memory, it would +again be wasteful. +
        +malloc allows us to allocate exactly the correct amount of memory and +with the use of free only for the time it is required. +

        +

        +
        +	Library:   stdlib.h
+
+	Prototype: void *malloc(size_t size);
+
+	Syntax:    char * String;
+
+                   String = (char *) malloc(1000);
+
        +
        +

        +Looking at the example syntax above, 1000 bytes are reserved and the pointer +String points to the first byte. The 1000 bytes are NOT initialized +by malloc. If the memory is NOT available, a +NULL pointer is returned. + +Please note, the cast cast is required to +return a pointer of the correct type. +

        Examples:

        + + example +program. + +

        +

        +

        See Also:

        + +char data type.

        + +free function.

        + + +sizeof operator.

        +

        + +

        C++

        + +new is the C++ equivalent to malloc.

        + + +delete is the C++ equivalent to +free.

        +
        +

        +printf is used to O/P data to +STDOUT (usually the screen). It has many +formatting options which we shall look at in a moment. + +

        +

        printf syntax

        +This is an example of printf in its simplest form. +

        +

        + + + + +
        +
        +
+  #include <stdio.h>
+
+  main()
+  {
+    printf("This text will appear on the screen\n");  
+  }
+
        +
        +
        +

        +printf is passed one formatting argument. +The unusual thing about the example (in my mind) is \n, this is actually +an escape sequence that signals a new line. Without +it, any printf's +that follow would O/P to the same line. +printf also takes extra arguments which are inserted into the format +string at locations marked with a %. +

        +

        + + + + +
        +
        +
+  #include <stdio.h>
+
+  main()
+  {
+    int number=42;
+    printf("The answer is %i\n", number);  
+  }
+
        +
        +
        +

        +What happens here is the %i is seen as a +formatting identifer for the +next argument (number). In this case an integer is expected.

        +

        Some explanation.

        +
          +
        • void * base
          Is a pointer to the array to be sorted. This can +be a pointer to any datatype. +

          +

        • size_t num
          The number of elements. +

          +

        • size_t size
          The element size. +

          +

        • int (*comp_func)(const void *, const void *))
          This is a +pointer to +a function. +
        + + +
        +

        Notes

        +
          +
        1. Well... This caused me alot of trouble! Although the prototype above is +exactly as shown in the documentation, the last parm kept giving compiler +warnings (invalid pointer type) this is the fix. +

+
+All three functions return information about a file. Please note 
+that devices are seen as files to Unix, so you could 'stat' things
+like /dev/mouse to see when the mouse was last moved.
        
+
+stat return the status of a file.
        
+
+fstat stats an open file.
        
+
+lstat reports on a link, not the file it points too.
        
+
        +Libraries: sys/stat.h

+
+st_mode can be used with the following macros to discover the 
+type of file being statted.
+
+
+
        +	S_ISLNK(st_mode)  is it a symbolic link
+
+        S_ISREG(st_mode)  regular file
+
+        S_ISDIR(st_mode)  directory
+
+        S_ISCHR(st_mode)  character device
+
+        S_ISBLK(st_mode)  block device
+
+        S_ISFIFO(st_mode) fifo
+
+        S_ISSOCK(st_mode) socket	
+
        
+
+These functions return a large amount of information. See the man page 
+(below) for details. You will need to understand 
+        structures to work with stat.
        
+
+
+

+
        Note
        
+I have seen a problem with the 'access time', it only seems to get updated
+if the file system is local. If the filesystem is NFS mounted and
+accessed via 'cat' or 'head' the access date is not updated.

        strcmp function

+
        
+
        
+strcmp will test two strings for equallity.
+
        +	Returns :
+		< 0 if s1 is less than s2
+		  0 if s1 == s2
+		> 0 if s1 is greater than s2
+
        
+This function probably provides too much information
+by indicating which string is lexicographically greater. The net result
+means that the strcmp return code is logically incorrect because
+it returns a FALSE value 
+when the strings match.

+
+'string2' is now a character pointer (only one byte) that points to a 
+storage location containing "red dwarf" (a 
+string constant).  So 
+string1=string2; copies the address of "red dwarf" into 
+'string1'. This version of the code will execute quicker than strcpy 
+because less data is being moved around the system.

        strtok function
        
+
        
+
        
+
        
+All the books that I have read, say that strtok will break a string 
+into tokens. This is true, but a more obvious 
+explanation is, that it will break a string into words.
+
        
+
        
+
        +
+Library:   string.h
+
+Prototype: char * strtok(char *s, const char *delim);
+
+Syntax:	   char string []="abc def ghi";
+	   char * word;
+
+	   word=strtok(string, " ");
+	   word=strtok(NULL, " ");
+
+
        
+
+strtok requires a string and the word delimiters, for example:
+
+
        +
+	   word = strtok(string, " ");
+	                   A      A
+	                   |      |
+	                   |	  -------  Delimiters.
+	                   |
+	                   --------------  String to break up.
+
+
        				
+After the first call to strtok, word will point to abc on the second
+call, word will point to def
+
        
+
        
+
        Notes:
        
+
          
+
        • strtok will alter the I/P string by placing 
+NULLS at the delimiter
+positions. A good habit is to copy 
+the string to a tempary string
+and use the copy in the strtok call.
+
          
+
        • More than one delimiter can be specified. So you could code:
+
          +
+	word = strtok(string, " \t;:,");
+	                         
+
          
+
        • You do not have to include \0 or NULL
+
        
+
        
+

        strtol function 
        
+
        
+
        
+
        
+strtol will convert a string to a long integer. An important feature 
+of this function is the ability to accept data in various number bases
+and convert to decimal. If 
+you are just working with decimal numbers,
+atoi is probably an easer function to use.
+
        
+

        +
+Library:   stdlib.h
+
+Prototype: long int strtol(const char *sptr, char **endptr, int base);

+
+           Ans = strtol(String, NULL, Base);
+
        
+
+
        
+
        Notes
        
+The second argument (char **endptr) seems to be a waste of space! If 
+it is set to NULL, STRTOL
+seems to work its way down the string until it finds an invalid character
+and then stops. All valid chars read are then converted if the string
+starts with an invalid character the function returns ZERO (0).
+
        
+The Third argument (base) can have a value of 0 or 2-32.
+
          
+
        • 0 - strtol will attempt to pick the base. Only Dec, Oct Hex  supported.

        uname function.
        
+
+uname is NOT in the ANSII library but is handy for getting 
+system information. It will return handy things like:
+
        
+System type (name).
        
+Host name (Nodename).
        
+Software release.
        
+Software date.
        
+Machine type.
        
+Domainname.

+GDB Debugger

+
        GDB Debugger
        
+
        
+
        
+
        
+The other common debug programs on Unix systems are dbx and dbxtool.
        
+Before a program can be processed by the debugger, it must be compiled 
+with the debugger option.
+
        +	gcc -ggdb -o pipe pipe.c
+
        
+The program can then be passed to the debugger with
+
        +	gdb pipe
+
        
+To pass command line parameters to the program use:
+
        +	set args -size big
+
        
+This is equivalent to saying:
+
        +	pipe -size big
+
        
+To single step:
+
        +	break
+	run
+	step
+
        
+The step command stops execution at the next source statement,
+if that statement is a function call, gdb will single step into the function.
+
        
+ A simular command is next this will also single step source 
+statements but when a it meets a function call, the function is executed 
+and gdb stops when it reaches a new source statement in the calling 
+function.
+
        
+step can be abreviated to s
+
        
+next can be abreviated to n
+
         
+To set break points:
+
        +	break 48	<-- Program will stop BEFORE executing line 48
+	break FuncName  <-- Program will stop when entering the function
+	run
+
        
+To display the contents of a variable:
+
        +	print ant[0]
+
        
+	
+To change the value of a variable:
+
        +	set ant[0] = 4
+	set char = 'z'
+
        
+
+

+
+Wot is a user library? I hear you ask! Well, its a collection of your 
+functions, that, when placed into a library are available to all the programs
+you write.
        
+This is what 
+Chris Sawtell
+has to say about libraries.
+
        
+There are two types of library, dynamic
+and static. Although dynamic libraries
+are the prefered alternative (because they are not linked
+into your program), here is the method required to create
+static libraries....
+
        
+There are several steps required in creating a library.
        
+
          
+
        • Create a function.
+
        • Create an object module of the function.
+
        • Add the object module to the library/archive.
+
        • Compile a program that uses the library/archive.
+
        
+
        
+Here are the four steps in UNIX terms. The function is called reverse 
+and the library is called mart.
+
        
+
        
+
+
+
        
+
        +
+ vi reverse.c			     # write your function (no main). 
+ gcc -c reverse.c		     # -c just compiles (no link).
+ ar -q  libmart.a reverse.o	     # -r == if nessasary replace 
+         			     #       an existing function.
+ gcc program.c -lmart -L/home/leslim # -l == library to search
+				     # -L == Location of the library.
+
        
+
        
+
        
+
        
+
+A few notes:
        
+
          
+
        • reverse.c should NOT contain a main.
+
        • A header file containing the prototype for reverse.c is required.
+
        • I expected to be able to add /home/leslim to LD_LIBRARY_PATH but 
+gcc does not seem to look at this variable for its list of libraries.
+
        • If you dont want to use the -L option you will have  to place
+your library in a directory like /usr/lib.
+
        • DONT LOOSE THE SOURCE! You cant rebuild the source from the object
+module. If you want to make a change at a later date you will want
+the source.
+
        
+
        
+Other usefull commands:
+
          
+
        • ar -t libmart.a  == List the Objects in a library.
+

+System calls and library calls

        System calls and library calls
        
+
        
+
        
+
        
+
+I have wondered for sometime what the difference is between
+system calls (found in section 2 of the man pages)
+and library calls (in section 3).
+
+Its simple...
+
+
          
+
        • system calls are provided by the system
+and are executed in the system kernel. They are entry points
+into the kernel and are therefore NOT linked into your
+program. These are not portable
+calls.
+
        • Library calls include the ANSI C standard library and are
+therefore portable. These functions are linked into your program.
+
        
+
+It is worth noting that, because system calls are part of the
+O/S. The program has to make a context switch to the kernel
+when they are called and because of this, they have a high
+startup overhead. The upside is that the time executing these
+routines is assigned to the OS and not the user program.
+

+
        NAME
+
               access - check user's permissions for a file
+
+
        SYNOPSIS
+
               #include <unistd.h>
+
+       int access(const char *pathname, int mode);
+
+
        DESCRIPTION
+
               access  checks  whether  the  process  would be allowed to
+       read, write or test for existence of the  file  (or  other
+       file system object) whose name is pathname.
+
+       mode  is  a  mask consisting of one or more of R_OK, W_OK,
+       X_OK and F_OK.
+
+       R_OK, W_OK and X_OK request testing for  reading,  writing
+       and  executing  the  file,  respectively.   F_OK  requests
+       checking whether merely testing for the existence  of  the
+       file  would be allowed (this depends on the permissions of
+       the directories in the path to the file, as given in path-
+       name.)
+
+       The  check  is  done  with the process's real uid and gid,
+       rather than with the effective ids as is done  when  actu-
+       ally  attempting  an  operation.  This is to allow set-UID
+       programs to easily determine the invoking  user's  author-
+       ity.
+
+       Only  access  bits  are checked, not the file type or con-
+       tents.   Therefore,  if  a  directory  is  found   to   be
+       "writable," it probably means that files can be created in
+       the directory, and not that the directory can  be  written
+       as a file.  Similarly, a DOS file may be found to be "exe-
+       cutable," but the execve(2) call will still fail.
+
+
        RETURN VALUE
+
               On success, zero is returned.  On error, -1  is  returned,
+       and errno is set appropriately.
+
+
        ERRORS
+
               EACCES  The  requested  access  would be denied, either to
+               the file itself or one of the directories in path-
+               name.
+
+       EFAULT  pathname  points  outside  your accessible address
+               space.
+
+       EINVAL  mode was incorrectly specified.
+
+       ENAMETOOLONG
+               pathname is too long.

+
        NAME
+
               acos - arc cosine function
+
+
        SYNOPSIS
+
               #include <math.h>
+
+       double acos(double x);
+
+
        DESCRIPTION
+
               The  acos()  function calculates the arc cosine of x; that
+       is the value whose cosine is x.  If x  falls  outside  the
+       range -1 to 1, acos() fails and errno is set.
+
+
        RETURN VALUE
+
               The  acos() function returns the arc cosine in radians and
+       the value is mathematically defined to be between 0 and PI
+       (inclusive).
+
+
        ERRORS
+
               EDOM   x is out of range.

+
        
+
+
        NAME
+
               alarm - set an alarm clock for delivery of a signal
+
+
        SYNOPSIS
+
               #include <unistd.h>
+
+       long alarm(long seconds);
+
+
        DESCRIPTION
+
               alarm arranges for a SIGALRM signal to be delivered to the
+       process in seconds seconds.
+
+       If seconds is zero, no new alarm is scheduled.
+
+       In any event any previously set alarm is cancelled.
+
+
        RETURN VALUE
+
               alarm returns the number of seconds  remaining  until  any
+       previously  scheduled  alarm  was  due to be delivered, or
+       zero if there was no previously scheduled alarm.
+
+
        NOTES
+
               alarm and setitimer share the same  timer;  calls  to  one
+       will interfere with use of the other.
+
+       Scheduling delays can, as ever, cause the execution of the
+       process to be delayed by an arbitrary amount of time.

        NAME
+
               asctime,  ctime,  gmtime,  localtime,  mktime  - transform
+       binary date and time to ASCII
+
+
        SYNOPSIS
+
               #include <time.h>
+
+       char *asctime(const struct tm *timeptr);
+
+       char *ctime(const time_t *timep);
+
+       struct tm *gmtime(const time_t *timep);
+
+       struct tm *localtime(const time_t *timep);
+
+       time_t mktime(struct tm *timeptr);
+
+       extern char *tzname[2];
+       long int timezone;
+       extern int daylight;
+
+
        DESCRIPTION
+
               The ctime(), gmtime() and localtime() functions  all  take
+       an  argument of data type time_t which represents calendar
+       time.  When interpreted as an absolute time value, it rep-
+       resents  the  number  of seconds elapsed since 00:00:00 on
+       January 1, 1970, Coordinated Universal Time (UTC).
+
+       The asctime() and mktime() functions both take an argument
+       representing  broken-down time which is a binary represen-
+       tation separated into year, month, day, etc.   Broken-down
+       time  is  stored  in  the structure tm which is defined in
+       <time.h> as follows:
+
+              struct tm
+              {
+                      int     tm_sec;         /* seconds */
+                      int     tm_min;         /* minutes */
+                      int     tm_hour;        /* hours */
+                      int     tm_mday;        /* day of the month */
+                      int     tm_mon;         /* month */
+                      int     tm_year;        /* year */
+                      int     tm_wday;        /* day of the week */
+                      int     tm_yday;        /* day in the year */
+                      int     tm_isdst;       /* daylight saving time */
+              };
+
+       The members of the tm structure are:
+
+       tm_sec The number of seconds after the minute, normally in
+              the range 0 to 59, but can be up to 61 to allow for
+              leap seconds.
+
+       tm_min The number of minutes after the hour, in the  range

+
+              0 to 59.
+
+       tm_hour
+              The  number  of hours past midnight, in the range 0
+              to 23.
+
+       tm_mday
+              The day of the month, in the range 1 to 31.
+
+       tm_mon The number of months since January, in the range  0
+              to 11.
+
+       tm_year
+              The number of years since 1900.
+
+       tm_wday
+              The  number of days since Sunday, in the range 0 to
+              6.
+
+       tm_yday
+              The number of days since January 1, in the range  0
+              to 365.
+
+       tm_isdst
+              A  flag that indicates whether daylight saving time
+              is in effect at the time described.  The  value  is
+              positive if daylight saving time is in effect, zero
+              if it is not, and negative if  the  information  is
+              not available.
+
+       The ctime() function converts the calendar time timep into
+       a string of the form
+
+              "Wed Jun 30 21:49:08 1993\n"
+
+       The abbreviations for the days  of  the  week  are  `Sun',
+       `Mon',  `Tue', `Wed', `Thu', `Fri', and `Sat'.  The abbre-
+       viations for the months are `Jan',  `Feb',  `Mar',  `Apr',
+       `May',  `Jun',  `Jul',  `Aug',  `Sep',  `Oct',  `Nov', and
+       `Dec'.  The return value points to a statically  allocated
+       string  which  might be overwritten by subsequent calls to
+       any of the date and time  functions.   The  function  also
+       sets  the  external variable tzname with information about
+       the current time zone.
+
+       The gmtime() function converts the calendar time timep  to
+       broken-down  time representation, expressed in Coordinated
+       Universal Time (UTC).
+
+       The localtime() function converts the calendar time  timep
+       to  broken-time  representation, expressed relative to the
+       user's specified  time  zone.     The  function  sets  the
+       external  variables tzname with information about the cur-
+       rent time  zone,  timezone  with  the  difference  between

+
+       Coordinated  Universal  Time (UTC) and local standard time
+       in seconds, and daylight to a non-zero value  if  standard
+       US daylight savings time rules apply.
+
+       The asctime() function converts the broken-down time value
+       timeptr into a string with the  same  format  as  ctime().
+       The  return  value points to a statically allocated string
+       which might be overwritten by subsequent calls to  any  of
+       the date and time functions.
+
+       The  mktime()  function converts a broken-down time struc-
+       ture  to  calendar  time  representation.   The   function
+       ignores  the  specified  contents of the structure members
+       tm_wday and tm_yday and recomputes  them  from  the  other
+       information  in  the  broken-down time structure.  Calling
+       mktime() also  sets  the  external  variable  tzname  with
+       information about the current time zone.  If the specified
+       broken-down time cannot be represented as  calendar  time,
+       mktime()  returns  a  value  of  (time_t)(-1) and does not
+       alter the tm_wday and tm_yday members of  the  broken-down
+       time structure.

+
        SYNOPSIS
+
               #include <math.h>
+
+       double asin(double x);
+
+
        DESCRIPTION
+
               The  asin() function calculates the arc sine of x; that is
+       the value whose sine is x.  If x falls outside  the  range
+       -1 to 1, asin() fails and errno is set.
+
+
        RETURN VALUE
+
               The  asin()  function  returns the arc sine in radians and
+       the value is mathematically defined to  be  between  -PI/2
+       and PI/2 (inclusive).
+
+
        ERRORS
+
               EDOM   x is out of range.

+
+
        NAME
+
               assert - Abort the program if assertion is false.
+
+
        SYNOPSIS
+
               #include <assert.h>
+
+       void assert (int expression);
+
+
        DESCRIPTION
+
               assert()  prints  an  error message to standard output and
+       terminates the program by calling abort() if expression is
+       false  (i.e.,  compares equal to zero).  This only happens
+       when the macro NDEBUG is undefined.
+
+
        RETURN VALUE
+
               No value is returned.
+
+
        CONFORMS TO
+
               ANSI - C
+
+
        BUGS
+
               assert() is implemented as  a  macro;  if  the  expression
+       tested  has side - effects, program behaviour will be dif-
+       ferent depending on whether NDEBUG is  defined.  This  may
+       create  Heisenbugs  which go away when debugging is turned
+       on.

        NAME
+
               atan2 - arc tangent function of two variables
+
+
        SYNOPSIS
+
               #include <math.h>
+
+       double atan2(double y, double x);
+
+
        DESCRIPTION
+
               The atan2() function calculates the arc tangent of the two
+       variables x and y.  It is similar to calculating  the  arc
+       tangent  of y / x, except that the signs of both arguments
+       are used to determine the quadrant of the result.
+
+
        RETURN VALUE
+
               The atan2() function returns the result in radians,  which
+       is between -PI and PI (inclusive).

        MALLOC(3)           Linux Programmer's Manual           MALLOC(3)
+
        
+
+
        NAME
+
               calloc,  malloc, free, realloc - Allocate and free dynamic
+       memory
+
+
        SYNOPSIS
+
               #include <stdlib.h>
+
+       void *calloc(size_t nmemb, size_t size);
+       void *malloc(size_t size);
+       void free(void *ptr);
+       void *realloc(void *ptr, size_t size);
+
+
        DESCRIPTION
+
               calloc() allocates memory for an array of  nmemb  elements
+       of  size bytes each and returns a pointer to the allocated
+       memory.  The memory is set to zero.
+
+       malloc() allocates size bytes and returns a pointer to the
+       allocated memory.  The memory is not cleared.
+
+       free()  frees  the  memory  space pointed to by ptr, which
+       must have been returned by a previous  call  to  malloc(),
+       calloc()  or  realloc().   If ptr is NULL, no operation is
+       performed.
+
+       realloc() changes the size of the memory block pointed  to
+       by  ptr  to size bytes.  The contents will be unchanged to
+       the minimum of the old an new sizes; newly allocated  mem-
+       ory  will  be  uninitialized.  If ptr is NULL, the call is
+       equivalent to malloc(size); if size is equal to zero,  the
+       call  is  equivalent to free(ptr).  Unless ptr is NULL, it
+       must have been returned by an earlier  call  to  malloc(),
+       calloc() or realloc().
+
+
        RETURN VALUES
+
               For calloc() and malloc(), the value returned is a pointer
+       to the allocated memory, which is suitably aligned for any
+       kind of variable, or NULL if the request fails.
+
+       free() returns no value.
+
+       realloc() returns a pointer to the newly allocated memory,
+       which is suitably aligned for any kind of variable and may
+       be  different from ptr, or NULL if the request fails or if
+       size was equal to 0.   If  realloc()  fails  the  original
+       block is left untouched - it is not freed or moved.

        CHDIR(2)            Linux Programmer's Manual            CHDIR(2)
+
        
+
+
        NAME
+
               chdir, fchdir - change working directory
+
+
        SYNOPSIS
+
               #include <unistd.h>
+
+       int chdir(const char *path);
+       int fchdir(int fd);
+
+
        DESCRIPTION
+
               chdir  changes  the current directory to that specified in
+       path.
+
+       fchdir is identical to chdir, only that the  directory  is
+       given as an open file descriptor.
+
+
        RETURN VALUE
+
               On  success,  zero is returned.  On error, -1 is returned,
+       and errno is set appropriately.
+
+
        ERRORS
+
               Depending  on  the  file  system,  other  errors  can   be
+       returned.  The more general errors are listed below:
+
+
+       EPERM   The  process  does  not have execute permission on
+               the directory.
+
+       EFAULT  path points outside your accessible address space.
+
+       ENAMETOOLONG
+               path is too long.
+
+       EBADF   The fd is not a valid file descriptor.
+
+       ENOENT  The file does not exist.
+
+       ENOMEM  Insufficient kernel memory was available.
+
+       ENOTDIR A component of the path prefix is not a directory.
+
+       EACCES  Search permission is denied on a component of  the
+               path prefix.
+
+       ELOOP   path  contains  a  circular reference (i.e., via a
+               symbolic link)

        NAME

               chown - change the user and group ownership of files
+
+
        SYNOPSIS

               chown  [-Rcfv]  [--recursive] [--changes] [--help] [--ver-
+       sion] [--silent] [--quiet]  [--verbose]  [user][:.][group]
+       file...
+
+
        DESCRIPTION
+
               This  manual  page  documents  the  GNU  version of chown.
+       chown changes the user  and/or  group  ownership  of  each
+       given  file,  according  to its first non-option argument,
+       which is interpreted as follows.  If only a user name  (or
+       numeric  user ID) is given, that user is made the owner of
+       each given file, and the files' group is not changed.   If
+       the  user  name  is followed by a colon or dot and a group
+       name (or numeric group ID), with no spaces  between  them,
+       the group ownership of the files is changed as well.  If a
+       colon or dot but no group name follows the user name, that
+       user  is  made the owner of the files and the group of the
+       files is changed to that user's login group.  If the colon
+       or  dot and group are given, but the user name is omitted,
+       only the group of the files  is  changed;  in  this  case,
+       chown performs the same function as chgrp.
+
+   OPTIONS
+       -c, --changes
+              Verbosely describe only files whose ownership actu-
+              ally changes.
+
+       -f, --silent, --quiet
+              Do not print error messages about files whose  own-
+              ership cannot be changed.
+
+       -v, --verbose
+              Verbosely describe ownership changes.
+
+       -R, --recursive
+              Recursively  change  ownership  of  directories and
+              their contents.
+
+       --help Print a usage message on standard output  and  exit
+              successfully.
+
+       --version
+              Print  version  information on standard output then
+              exit successfully.

+
        DESCRIPTION
+
               The clock() function returns an approximation of processor
+       time used by the program.
+
+
        RETURN VALUE
+
               The value returned is the  CPU  time  used  so  far  as  a
+       clock_t;  to  get  the  number  of seconds used, divide by
+       CLOCKS_PER_SEC.

        BUGS
+
               The C standard allows for arbitrary values at the start of

+       returned from a call to clock() at the start of  the  pro-
+       gram and the end to get maximum portability.
+
+       The times() function call returns more information.

+
        NAME
+
               close - close a file descriptor
+
+
        SYNOPSIS
+
               #include <unistd.h>
+
+       int close(int fd);
+
+
        DESCRIPTION
+
               close  closes  a  file  descriptor,  so  that it no longer
+       refers to any file and may be reused.
+
+       If fd is the last copy of a particular file descriptor the
+       resources  associated  with  it are freed; for example any
+       locks held are removed and if the descriptor was the  last
+       reference  to  a  file which has been removed using unlink
+       the file is deleted.
+
+
        RETURN VALUE
+
               close returns zero on success, or -1 if an error occurred.
+
+
        ERRORS
+
               EBADF  fd isn't a valid open file descriptor.
+
+
        CONFORMING TO
+

+
+
        NOTES
+
               Not  checking  the  return  value of close is a common but
+       nevertheless  serious  programming  error.   File   system
+       implementations  which  use techniques as ``write-behind''
+       to increase performance may lead to  write(2)  succeeding,
+       although  the  data  has  not been written yet.  The error
+       status may be reported at a later write operation, but  it
+       is  guaranteed  to  be  reported on closing the file.  Not
+       checking the return value when closing the file  may  lead
+       to  silent  loss of data.  This can especially be observed
+       with NFS and disk quotas.

        NAME

               #include <stdio.h>
+
+       char *ctermid(char *s);
+
+
        DESCRIPTION
+
               ctermid()  returns  a string which is the pathname for the
+       current controlling terminal for this process.   If  s  is
+       NULL,  a  static  buffer  is used, otherwise s points to a
+       buffer used to hold the terminal pathname.   The  symbolic
+       constant  L_ctermid is the maximum number of characters in
+       the returned pathname.
+
+
        RETURN VALUE
+
               The pointer to the pathname.
+

+
+
        BUGS
+
               The path returned may not uniquely identify  the  control-
+       ling terminal; it may, for example, be /dev/tty.
+
+       It  is not assured that the program can open the terminal.

        DUP(2)              Linux Programmer's Manual              DUP(2)
+
        
+
+
        NAME
+
               dup, dup2 - duplicate a file descriptor
+
+
        SYNOPSIS
+
               #include <unistd.h>
+
+       int dup(int oldfd);
+       int dup2(int oldfd, int newfd);
+
+
        DESCRIPTION
+
               dup and dup2 create a copy of the file descriptor oldfd.
+
+       The  old  and new descriptors may be used interchangeably.
+       They share locks, file position pointers  and  flags;  for
+       example,  if  the file position is modified by using lseek
+       on one of the descriptors, the position  is  also  changed
+       for the other.
+
+       The  two  descriptors do not share the close-on-exec flag,
+       however.
+
+       dup uses the lowest-numbered unused descriptor for the new
+       descriptor.
+
+       dup2 makes newfd be the copy of oldfd, closing newfd first
+       if necessary.
+
+
        RETURN VALUE
+
               dup and dup2 return the new descriptor, or -1 if an  error
+       occurred (in which case, errno is set appropriately).
+
+
        ERRORS
+
               EBADF  oldfd  isn't  an  open file descriptor, or newfd is

        DUP(2)              Linux Programmer's Manual              DUP(2)
+
        
+
+
        NAME
+
               dup, dup2 - duplicate a file descriptor
+
+
        SYNOPSIS
+
               #include <unistd.h>
+
+       int dup(int oldfd);
+       int dup2(int oldfd, int newfd);
+
+
        DESCRIPTION
+
               dup and dup2 create a copy of the file descriptor oldfd.
+
+       The  old  and new descriptors may be used interchangeably.
+       They share locks, file position pointers  and  flags;  for
+       example,  if  the file position is modified by using lseek
+       on one of the descriptors, the position  is  also  changed
+       for the other.
+
+       The  two  descriptors do not share the close-on-exec flag,
+       however.
+
+       dup uses the lowest-numbered unused descriptor for the new
+       descriptor.
+
+       dup2 makes newfd be the copy of oldfd, closing newfd first
+       if necessary.
+
+
        RETURN VALUE
+
               dup and dup2 return the new descriptor, or -1 if an  error
+       occurred (in which case, errno is set appropriately).
+
+
        ERRORS
+
               EBADF  oldfd  isn't  an  open file descriptor, or newfd is
+              out of the allowed range for file descriptors.
+
+       EMFILE The process already has the maximum number of  file
+              descriptors open and tried to open a new one.
+
+
        WARNING
+
               The  error  returned by dup2 is different to that returned
+       by fcntl(...,F_DUPFD,...)  when newfd is out of range.  On

        EXP(3)              Linux Programmer's Manual              EXP(3)
+
        
+
+
        NAME
+
               exp,  log, log10, pow - exponential, logarithmic and power
+       functions
+
+
        SYNOPSIS
+
               #include <math.h>
+
+       double exp(double x);
+
+       double log(double x);
+
+       double log10(double x);
+
+       double pow(double x, double y);
+
+
        DESCRIPTION
+
               The exp() function returns the value of  e  (the  base  of
+       natural logarithms) raised to the power of x.
+
+       The log() function returns the natural logarithm of x.
+
+       The log10() function returns the base-10 logarithm of x.
+
+       The  pow()  function  returns the value of x raised to the
+       power of y.
+
+
        ERRORS
+
               The log() and log10() functions can return  the  following
+       errors:
+
+       EDOM   The argument x is negative.
+
+       ERANGE The  argument  x  is  zero.  The log of zero is not
+              defined.
+
+       The pow() function can return the following error:
+
+       EDOM   The argument x is negative and y is not an integral
+              value.  This would result in a complex number.

        FFLUSH(3)           Linux Programmer's Manual           FFLUSH(3)
+
        
+
+
        NAME
+
               fflush, fpurge - flush a stream
+
+
        SYNOPSIS
+
               #include <stdio.h>
+
+       int fflush( FILE *stream);
+       int fpurge( FILE *stream);
+
+
        DESCRIPTION
+
               The  function  fflush  forces a write of all buffered data
+       for the given output or update  stream  via  the  stream's
+       underlying  write function.  The open status of the stream
+       is unaffected.
+
+       If the stream argument is NULL, fflush  flushes  all  open
+       output streams. (Does this happen under Linux)
+
+       The function fpurge erases any input or output buffered in
+       the given stream.  For output streams  this  discards  any
+       unwritten  output.   For  input  streams this discards any
+       input read from the underlying object but not yet obtained
+       via  getc(3);  this  includes  any  text  pushed  back via
+       ungetc.
+
+
        RETURN VALUES
+
               Upon successful completion 0 is returned.  Otherwise,  EOF
+       is  returned and the global variable errno is set to indi-
+       cate the error.
+
+
        ERRORS
+
               EBADF  Stream is not an open stream, or, in  the  case  of
+              fflush, not a stream open for writing.
+
+       The function fflush may also fail and set errno for any of
+       the errors specified for the routine write(2).
+
+
        BUGS
+
               Linux may not support fpurge.

+       sured in bytes, is obtained by adding offset bytes to  the
+       position  specified  by  whence.   If  whence  is  set  to
+       SEEK_SET, SEEK_CUR, or SEEK_END, the offset is relative to
+       the  start of the file, the current position indicator, or
+       end-of-file, respectively.  A successful call to the fseek
+       function  clears  the end-of-file indicator for the stream
+       and undoes any effects of the ungetc(3)  function  on  the
+       same stream.
+
+       The  ftell  function obtains the current value of the file
+       position indicator for the stream pointed to by stream.
+
+       The rewind function sets the file position  indicator  for
+       the  stream  pointed  to by stream to the beginning of the
+       file.  It is equivalent to:
+
+              (void)fseek(stream, 0L, SEEK_SET)
+
+       except that the error indicator for  the  stream  is  also
+       cleared (see clearerr(3).
+
+       The fgetpos and fsetpos functions are alternate interfaces
+       equivalent  to  ftell  and  fseek  (with  whence  set   to
+       SEEK_SET),  setting  and  storing the current value of the
+       file offset into or from the object referenced by pos.  On
+       some  non-UNIX  systems  an fpos_t object may be a complex
+       object and these routines may be the only way to  portably
+       reposition a text stream.
+
+
        RETURN VALUES
+
               The  rewind  function  returns  no value.  Upon successful
+       completion, fgetpos, fseek, fsetpos return  0,  and  ftell
+       returns the current offset.  Otherwise, -1 is returned and
+       the global variable errno is set to indicate the error.
+
+
        ERRORS
+
               EBADF  The stream specified is not a seekable stream.

        FGETPWENT(3)        Linux Programmer's Manual        FGETPWENT(3)
+
        
+
+
        NAME
+
               fgetpwent - get password file entry
+
+
        SYNOPSIS
+
               #include <pwd.h>
+       #include <stdio.h>
+       #include <sys/types.h>
+
+       struct passwd *fgetpwent(FILE *stream);
+
+
        DESCRIPTION
+
               The  fgetpwent() function returns a pointer to a structure
+       containing the broken out fields of a  line  in  the  file
+       stream.   The first time it is called it returns the first
+       entry; thereafter, it  returns  successive  entries.   The
+       file stream must have the same format as /etc/passwd.
+
+       The passwd structure is defined in <pwd.h> as follows:
+
+              struct passwd {
+                      char    *pw_name;       /* user name */
+                      char    *pw_passwd;     /* user password */
+                      uid_t   pw_uid;         /* user id */
+                      gid_t   pw_gid;         /* group id */
+                      char    *pw_gecos;      /* real name */
+                      char    *pw_dir;        /* home directory */
+                      char    *pw_shell;      /* shell program */
+              };
+
+
        RETURN VALUE
+
               The  fgetpwent() function returns the passwd structure, or
+       NULL if there are no more entries or an error occurs.
+
+
        ERRORS
+
               ENOMEM Insufficient memory to allocate passwd structure.

+
+
        NAME
+
               fopen, fdopen, freopen - stream open functions
+
+
        SYNOPSIS
+
               #include <stdio.h>
+
+       FILE *fopen( char *path, char *mode);
+       FILE *fdopen( int fildes, char *mode);
+       FILE *freopen( char *path, char *mode, FILE *stream);
+
+
        DESCRIPTION
+
               The fopen function opens the file whose name is the string
+       pointed to by path and associates a stream with it.
+
+       The argument mode points to a string beginning with one of
+       the  following sequences (Additional characters may follow
+       these sequences.):
+
+       r      Open text file for reading.  The  stream  is  posi-
+              tioned at the beginning of the file.
+
+       r+     Open  for reading and writing.  The stream is posi-
+              tioned at the beginning of the file.
+
+       w      Truncate file to zero length or  create  text  file
+              for  writing.   The  stream  is  positioned  at the
+              beginning of the file.
+
+       w+     Open for reading and writing.  The file is  created
+              if  it  does  not exist, otherwise it is truncated.
+              The stream is positioned at the  beginning  of  the
+              file.
+
+       a      Open  for  writing.  The file is created if it does
+              not exist.  The stream is positioned at the end  of
+              the file.
+
+       a+     Open  for reading and writing.  The file is created
+              if it does not exist.  The stream is positioned  at
+              the end of the file.
+
+       The  mode  string can also include the letter ``b'' either
+       as a third character or as a character between the charac-
+       ters  in any of the two-character strings described above.
+       This is strictly for compatibility with  ANSI  C3.159-1989
+       (``ANSI  C'')  and  has  no  effect; the ``b'' is ignored.
+       Linux may not behave this way.
+
+       Any      created      files      will      have       mode
+       S_IRUSR|S_IWUSR|S_IRGRP|S_IWGRP|S_IROTH|S_IWOTH (0666), as
+       modified by the process' umask value (see umask(2).
+
+       Reads and writes may be intermixed on  read/write  streams
+       in  any  order, and do not require an intermediate seek as

+       in previous versions of stdio.  This is  not  portable  to
+       other  systems,  however,  and  may  not  work under Linux
+       (someone should find out and fix  this  manpage);  ANSI  C
+       requires   that  a  file  positioning  function  intervene
+       between  output  and  input,  unless  an  input  operation
+       encounters end-of-file.
+
+       The  fdopen function associates a stream with the existing
+       file descriptor, fildes.  The mode of the stream  must  be
+       compatible with the mode of the file descriptor.
+
+       The  freopen  function  opens  the  file whose name is the
+       string pointed  to  by  path  and  associates  the  stream
+       pointed  to by stream with it.  The original stream (if it
+       exists) is closed.  The mode argument is used just  as  in
+       the  fopen function.  The primary use of the freopen func-
+       tion is to change the file associated with a standard text
+       stream (stderr, stdin, or stdout).
+
+
        RETURN VALUES
+
               Upon  successful  completion  fopen,  fdopen  and  freopen
+       return a FILE pointer.  Otherwise, NULL  is  returned  and
+       the global variable errno is set to indicate the error.
+
+
        ERRORS
+
               EINVAL The  mode provided to fopen, fdopen, or freopen was
+              invalid.
+
+       The fopen, fdopen and freopen functions may also fail  and
+       set  errno for any of the errors specified for the routine
+       malloc(3).

+       The fopen function may also fail and set errno for any  of
+       the errors specified for the routine open(2).

+
        NAME
+
               fpathconf, pathconf - get configuration values for files
+
+
        SYNOPSIS
+
               #include <unistd.h>
+
+       long fpathconf(int filedes, int name);
+       long pathconf(char *path, int name);
+
+
        DESCRIPTION
+
               fpathconf() gets a value for the configuration option name
+       for the open file descriptor filedes.
+
+       pathconf() gets a value for configuration option name  for
+       the file name path.
+
+       The  corresponding  macros  defined  in <unistd.h> minimum
+       values; if an application wants to take advantage of  val-
+       ues  which may change, a call to fpathconf() or pathconf()
+       can be made, which may yield more liberal results.
+
+       Setting name equal  to  one  of  the  following  constants
+       returns the following configuration options:
+
+       _PC_LINK_MAX

+              tory.   The corresponding macro is _POSIX_PATH_MAX.
+
+       _PC_PIPE_BUF
+              returns the size of the pipe buffer, where  filedes

+
        NAME
+
               fputc,  fputs,  putc, putchar, puts - output of characters
+       and strings
+
+
        SYNOPSIS
+
               #include <stdio.h>
+
+       int fputc(int c, FILE *stream);
+       int fputs(const char *s, FILE *stream);
+       int putc(int c, FILE *stream);
+       int putchar(int c);
+       int puts(char *s);
+       int ungetc(int c, FILE *stream);
+
+
        DESCRIPTION
+
               fputc() writes the character c, cast to an unsigned  char,
+       to stream.
+
+       fputs()  writes the string s to stream, without its trail-
+       ing '\0'.
+
+       putc() is equivalent to fputc()  except  that  it  may  be
+       implemented  as  a  macro which evaluates stream more than
+       once.
+
+       putchar(c); is equivalent to putc(c,stdout).
+
+       puts() writes the string s and a trailing newline to  std-
+       out.
+
+       Calls  to  the  functions described here can be mixed with
+       each other and with calls to other output  functions  from
+       the stdio library for the same output stream.
+
+
        RETURN VALUES
+
               fputc(), putc() and putchar() return the character written
+       as an unsigned char cast to an int or EOF on error.
+
+       puts() and fputs() return a non - negative number on  suc-
+       cess, or EOF on error.
+
+
+
        CONFORMS TO
+
               ANSI - C, POSIX.1
+
+
        BUGS
+
               It  is not advisable to mix calls to output functions from
+       the stdio library with low - level calls  to  write()  for
+       the  file  descriptor  associated  with  the  same  output
+       stream; the results will be undefined  and  very  probably
+       not what you want.

+
        NAME
+
               fread, fwrite - binary stream input/output
+
+
        SYNOPSIS
+
               #include <stdio.h>
+
+       int  fread(  void  *ptr,  size_t  size, size_t nmemb, FILE
+       *stream);
+
+       int fwrite( void *ptr, size_t  size,  size_t  nmemb,  FILE
+       *stream);
+
+
        DESCRIPTION
+
               The function fread reads nmemb elements of data, each size
+       bytes long, from the stream pointed to by stream,  storing
+       them at the location given by ptr.
+
+       The  function  fwrite  writes nmemb elements of data, each
+       size bytes long, to  the  stream  pointed  to  by  stream,
+       obtaining them from the location given by ptr.
+
+
        RETURN VALUES
+
               fread  and  fwrite return the number of items successfully
+       read or written (i.e., not the number of characters).   If
+       an error occurs, or the end-of-file is reached, the return
+       value is a short item count (or zero).
+
+       fread does not distinguish between end-of-file and  error,
+       and  callers  must  use feof(3) and ferror(3) to determine
+       which occurred.

+
        NAME
+
               fopen, fdopen, freopen - stream open functions
+
+
        SYNOPSIS
+
               #include <stdio.h>
+
+       FILE *fopen( char *path, char *mode);
+       FILE *fdopen( int fildes, char *mode);
+       FILE *freopen( char *path, char *mode, FILE *stream);
+
+
        DESCRIPTION
+
               The fopen function opens the file whose name is the string
+       pointed to by path and associates a stream with it.
+
+       The argument mode points to a string beginning with one of
+       the  following sequences (Additional characters may follow
+       these sequences.):
+
+       r      Open text file for reading.  The  stream  is  posi-
+              tioned at the beginning of the file.
+
+       r+     Open  for reading and writing.  The stream is posi-
+              tioned at the beginning of the file.
+
+       w      Truncate file to zero length or  create  text  file
+              for  writing.   The  stream  is  positioned  at the
+              beginning of the file.
+
+       w+     Open for reading and writing.  The file is  created
+              if  it  does  not exist, otherwise it is truncated.
+              The stream is positioned at the  beginning  of  the
+              file.
+
+       a      Open  for  writing.  The file is created if it does
+              not exist.  The stream is positioned at the end  of
+              the file.
+
+       a+     Open  for reading and writing.  The file is created
+              if it does not exist.  The stream is positioned  at
+              the end of the file.
+
+       The  mode  string can also include the letter ``b'' either
+       as a third character or as a character between the charac-
+       ters  in any of the two-character strings described above.
+       This is strictly for compatibility with  ANSI  C3.159-1989
+       (``ANSI  C'')  and  has  no  effect; the ``b'' is ignored.
+       Linux may not behave this way.
+
+       Any      created      files      will      have       mode
+       S_IRUSR|S_IWUSR|S_IRGRP|S_IWGRP|S_IROTH|S_IWOTH (0666), as
+       modified by the process' umask value (see umask(2).
+
+       Reads and writes may be intermixed on  read/write  streams
+       in  any  order, and do not require an intermediate seek as

+
+       in previous versions of stdio.  This is  not  portable  to
+       other  systems,  however,  and  may  not  work under Linux
+       (someone should find out and fix  this  manpage);  ANSI  C
+       requires   that  a  file  positioning  function  intervene
+       between  output  and  input,  unless  an  input  operation
+       encounters end-of-file.
+
+       The  fdopen function associates a stream with the existing
+       file descriptor, fildes.  The mode of the stream  must  be
+       compatible with the mode of the file descriptor.
+
+       The  freopen  function  opens  the  file whose name is the
+       string pointed  to  by  path  and  associates  the  stream
+       pointed  to by stream with it.  The original stream (if it
+       exists) is closed.  The mode argument is used just  as  in
+       the  fopen function.  The primary use of the freopen func-
+       tion is to change the file associated with a standard text
+       stream (stderr, stdin, or stdout).
+
+
        RETURN VALUES
+
               Upon  successful  completion  fopen,  fdopen  and  freopen
+       return a FILE pointer.  Otherwise, NULL  is  returned  and
+       the global variable errno is set to indicate the error.
+
+
        ERRORS
+
               EINVAL The  mode provided to fopen, fdopen, or freopen was
+              invalid.
+
+       The fopen, fdopen and freopen functions may also fail  and
+       set  errno for any of the errors specified for the routine
+       malloc(3).
+
+       The fopen function may also fail and set errno for any  of
+       the errors specified for the routine open(2).
+
+       The fdopen function may also fail and set errno for any of
+       the errors specified for the routine fcntl(2).
+
+       The freopen function may also fail and set errno  for  any
+       of   the   errors  specified  for  the  routines  open(2),
+       fclose(3) and fflush(3).

+
+
        NAME
+
               frexp  -  convert  floating-point number to fractional and
+       integral components
+
+
        SYNOPSIS
+
               #include <math.h>
+
+       double frexp(double x, int *exp);
+
+
        DESCRIPTION
+
               The frexp() function is used to split the number x into  a
+       normalized  fraction  and  an  exponent which is stored in
+       exp.
+
+
        RETURN VALUE
+
               The frexp() function returns the normalized fraction.   If
+       the  argument  x is not zero, the normalized fraction is x
+       times a power of two, and  is  always  in  the  range  1/2
+       (inclusive) to 1 (exclusive).  If x is zero, then the nor-
+       malized fraction is zero and zero is stored in exp.

        NAME

               scanf,  fscanf,  sscanf,  vscanf, vsscanf, vfscanf - input
+       format conversion
+
+
        SYNOPSIS
+
               #include <stdio.h>
+       int scanf( const char *format, ...);
+       int fscanf( FILE *stream, const char *format, ...);
+       int sscanf( const char *str, const char *format, ...);
+
+       #include <stdarg.h>
+       int vscanf( const char *format, va_list ap);
+       int vsscanf( const char *str, const char *format, va_list ap);
+       int vfscanf( FILE *stream, const char *format, va_list ap);
+
+
        DESCRIPTION
+
               The scanf family of functions scans input according  to  a
+       format  as  described below.  This format may contain con-
+       version specifiers; the results from such conversions,  if
+       any,  are stored through the pointer arguments.  The scanf
+       function reads input from the standard input stream stdin,
+       fscanf  reads  input  from  the stream pointer stream, and
+       sscanf reads its input from the character  string  pointed
+       to by str.
+
+       The vfscanf function is analogous to vfprintf(3) and reads
+       input from the stream  pointer  stream  using  a  variable
+       argument  list  of  pointers  (see  stdarg(3).  The vscanf
+       function scans a variable argument list from the  standard
+       input  and  the  vsscanf  function scans it from a string;
+       these are analogous to the vprintf and vsprintf  functions
+       respectively.
+
+       Each  successive pointer argument must correspond properly
+       with each successive conversion specifier (but  see  `sup-
+       pression' below).  All conversions are introduced by the %
+       (percent sign) character.  The format string may also con-
+       tain other characters.  White space (such as blanks, tabs,
+       or newlines) in the format  string  match  any  amount  of
+       white  space,  including  none,  in the input.  Everything
+       else matches only itself.  Scanning stops  when  an  input
+       character  does  not match such a format character.  Scan-
+       ning also stops when an input conversion  cannot  be  made
+       (see below).
+
+
        CONVERSIONS
+
               Following  the  % character introducing a conversion there
+       may be a number of flag characters, as follows:
+
+       *      Suppresses assignment.  The conversion that follows
+              occurs as usual, but no pointer is used; the result
+              of the conversion is simply discarded.
+
+       h      Indicates that the conversion will be one of  dioux

+
+              or  n  and the next pointer is a pointer to a short
+              int (rather than int).
+
+       l      Indicates either that the conversion will be one of
+              dioux  or  n and the next pointer is a pointer to a
+              long int (rather than int), or that the  conversion
+              will  be  one  of  efg  and  the  next pointer is a
+              pointer to double (rather than float).
+
+       L      Indicates that the conversion will be efg  and  the
+              next  pointer  is  a pointer to long double.  (This
+              type is not implemented; the L  flag  is  currently
+              ignored--this may not be true for Linux.)
+
+       In addition to these flags, there may be an optional maxi-
+       mum field width, expressed as a decimal  integer,  between
+       the % and the conversion.  If no width is given, a default
+       of `infinity' is used (with one exception, below);  other-
+       wise  at most this many characters are scanned in process-
+       ing the conversion.  Before conversion begins,  most  con-
+       versions skip white space; this white space is not counted
+       against the field width.
+
+       The following conversions are available:
+
+       %      Matches a literal `%'.  That is, `%%' in the format
+              string  matches  a  single input `%' character.  No
+              conversion is done, and assignment does not  occur.
+
+       d      Matches  an  optionally signed decimal integer; the
+              next pointer must be a pointer to int.
+
+       D      Equivalent to ld; this exists  only  for  backwards
+              compatibility.
+
+       i      Matches  an  optionally  signed  integer;  the next
+              pointer must be a pointer to int.  The  integer  is
+              read  in base 16 if it begins with `0x' or `0X', in
+              base 8 if it begins with `0', and in base 10 other-
+              wise.   Only characters that correspond to the base
+              are used.
+
+       o      Matches an octal integer; the next pointer must  be
+              a pointer to unsigned int.
+
+       O      Equivalent to lo; this exists for backwards compat-
+              ibility.
+
+       u      Matches an optionally signed decimal  integer;  the
+              next pointer must be a pointer to unsigned int.
+
+       x      Matches an optionally a signed hexadecimal integer;
+              the next pointer must be a pointer to unsigned int.

+       F      Equivalent to lf; this exists  only  for  backwards
+              compatibility.
+
+       s      Matches  a  sequence of non-white-space characters;
+              the next pointer must be a pointer to char, and the
+              array  must  be  large  enough  to  accept  all the
+              sequence and the terminating  NUL  character.   The
+              input string stops at white space or at the maximum
+              field width, whichever occurs first.
+
+       c      Matches  a  sequence  of  width  count   characters
+              (default  1); the next pointer must be a pointer to
+              char, and there must be enough  room  for  all  the
+              characters  (no  terminating  NUL  is  added).  The
+              usual skip of leading white  space  is  suppressed.
+              To skip white space first, use an explicit space in
+              the format.
+
+       [      Matches a nonempty sequence of characters from  the
+              specified  set  of  accepted  characters;  the next
+              pointer must be a pointer to char, and  there  must
+              be  enough  room  for  all  the  characters  in the
+              string, plus  a  terminating  NUL  character.   The
+              usual  skip  of  leading white space is suppressed.
+              The string is to be made up of  characters  in  (or
+              not in) a particular set; the set is defined by the
+              characters between the open bracket [ character and
+              a  close  bracket  ]  character.   The set excludes
+              those characters if the first character  after  the
+              open bracket is a circumflex ^.  To include a close
+              bracket in the set, make  it  the  first  character
+              after the open bracket or the circumflex; any other
+              position will end the set.  The hyphen character  -
+              is  also  special;  when  placed  between two other
+              characters, it adds all intervening  characters  to
+              the  set.   To  include  a hyphen, make it the last
+              character before  the  final  close  bracket.   For

+              instance,  `[^]0-9-]'  means  the  set  `everything
+              except  close  bracket,  zero  through  nine,   and
+              hyphen'.   The string ends with the appearance of a
+              character not in the (or, with  a  circumflex,  in)
+              set or when the field width runs out.
+
+       p      Matches  a  pointer  value  (as  printed by `%p' in
+              printf(3); the next pointer must be  a  pointer  to
+              void.
+
+       n      Nothing is expected; instead, the number of charac-
+              ters consumed thus far from  the  input  is  stored
+              through  the  next pointer, which must be a pointer
+              to int.  This is not a conversion, although it  can
+              be suppressed with the * flag.
+
+       For  backwards  compatibility, other conversion characters
+       (except `\0') are taken as if they were `%d' or, if upper-
+       case, `%ld', and a `conversion' of `%\0' causes an immedi-
+       ate return of EOF.   The  F  and  X  conversions  will  be
+       changed in the future to conform to the
+        ANSI  C  standard,  after  which  they  will act like and
+       respectively.  The behavior of Linux on  the  non-standard
+       points is not known by this documenter.
+
+
+
        RETURN VALUES
+
               These functions return the number of input items assigned,
+       which can be fewer than provided for, or even zero, in the
+       event  of  a matching failure.  Zero indicates that, while
+       there was input available, no conversions  were  assigned;
+       typically  this is due to an invalid input character, such
+       as an alphabetic character for  a  `%d'  conversion.   The
+       value  EOF  is  returned if an input failure occurs before
+       any conversion such as an end-of-file occurs. If an  error
+       or end-of-file occurs after conversion has begun, the num-
+       ber of conversions which were  successfully  completed  is
+       returned.

        FSEEK(3)            Linux Programmer's Manual            FSEEK(3)

+
+
        NAME
+
               fgetpos,  fseek,  fsetpos,  ftell,  rewind  - reposition a
+       stream
+
+
        SYNOPSIS
+
               #include <stdio.h>
+
+       int fseek( FILE *stream, long offset, int whence);
+       long ftell( FILE *stream);
+       void rewind( FILE *stream);
+       int fgetpos( FILE *stream, fpos_t *pos);
+       int fsetpos( FILE *stream, fpos_t *pos);
+
+
        DESCRIPTION
+
               The fseek function sets the file  position  indicator  for
+       the  stream  pointed to by stream.  The new position, mea-
+       sured in bytes, is obtained by adding offset bytes to  the
+       position  specified  by  whence.   If  whence  is  set  to
+       SEEK_SET, SEEK_CUR, or SEEK_END, the offset is relative to
+       the  start of the file, the current position indicator, or
+       end-of-file, respectively.  A successful call to the fseek
+       function  clears  the end-of-file indicator for the stream
+       and undoes any effects of the ungetc(3)  function  on  the
+       same stream.
+
+       The  ftell  function obtains the current value of the file
+       position indicator for the stream pointed to by stream.
+
+       The rewind function sets the file position  indicator  for
+       the  stream  pointed  to by stream to the beginning of the
+       file.  It is equivalent to:
+
+              (void)fseek(stream, 0L, SEEK_SET)
+
+       except that the error indicator for  the  stream  is  also
+       cleared (see clearerr(3).
+
+       The fgetpos and fsetpos functions are alternate interfaces
+       equivalent  to  ftell  and  fseek  (with  whence  set   to
+       SEEK_SET),  setting  and  storing the current value of the
+       file offset into or from the object referenced by pos.  On
+       some  non-UNIX  systems  an fpos_t object may be a complex
+       object and these routines may be the only way to  portably
+       reposition a text stream.
+
+
        RETURN VALUES
+
               The  rewind  function  returns  no value.  Upon successful
+       completion, fgetpos, fseek, fsetpos return  0,  and  ftell
+       returns the current offset.  Otherwise, -1 is returned and
+       the global variable errno is set to indicate the error.
+
+
        ERRORS
+
               EBADF  The stream specified is not a seekable stream.

        NAME
+
               fread, fwrite - binary stream input/output
+
+
        SYNOPSIS
+
               #include <stdio.h>
+
+       int  fread(  void  *ptr,  size_t  size, size_t nmemb, FILE
+       *stream);
+
+       int fwrite( void *ptr, size_t  size,  size_t  nmemb,  FILE
+       *stream);
+
+
        DESCRIPTION
+
               The function fread reads nmemb elements of data, each size
+       bytes long, from the stream pointed to by stream,  storing
+       them at the location given by ptr.
+
+       The  function  fwrite  writes nmemb elements of data, each
+       size bytes long, to  the  stream  pointed  to  by  stream,
+       obtaining them from the location given by ptr.
+
+
        RETURN VALUES
+
               fread  and  fwrite return the number of items successfully
+       read or written (i.e., not the number of characters).   If
+       an error occurs, or the end-of-file is reached, the return
+       value is a short item count (or zero).
+
+       fread does not distinguish between end-of-file and  error,
+       and  callers  must  use feof(3) and ferror(3) to determine
+       which occurred.

+
        STANDARDS
+
               The functions fread and fwrite conform to ANSI C3.159-1989
+       (``ANSI C'').

        GETC(3)             Linux Programmer's Manual             GETC(3)

+
+
        NAME
+
               fgetc, fgets, getc, getchar, gets, ungetc - input of char-
+       acters and strings
+
+
        SYNOPSIS
+
               #include <stdio.h>
+
+       int fgetc(FILE *stream);
+       char *fgets(char *s, int size, FILE *stream);
+       int getc(FILE *stream);
+       int getchar(void);
+       char *gets(char *s);
+       int ungetc(int c, FILE *stream);
+
+
        DESCRIPTION
+
               fgetc() reads the next character from stream  and  returns
+       it  as  an  unsigned char cast to an int, or EOF on end of
+       file or error.
+
+       getc() is equivalent to fgetc()  except  that  it  may  be
+       implemented  as  a  macro which evaluates stream more than
+       once.
+
+       getchar() is equivalent to getc(stdin).
+
+       gets() reads a line from stdin into the buffer pointed  to
+       by  s  until either a terminating newline or EOF, which it
+       replaces with '\0'.  No check for buffer overrun  is  per-
+       formed (see BUGS below).
+
+       fgets()  reads  in at most one less than n characters from
+       stream and stores them into the buffer pointed  to  by  s.
+       Reading  stops after an EOF or a newline.  If a newline is
+       read, it is stored into the  buffer.   A  '\0'  is  stored
+       after the last character in the buffer.
+
+       ungetc()  pushes  c back to stream, cast to unsigned char,
+       where it is  available  for  subsequent  read  operations.
+       Pushed  -  back  characters  will  be  returned in reverse
+       order; only one pushback is guaranteed.
+
+       Calls to the functions described here can  be  mixed  with
+       each  other  and  with calls to other input functions from
+       the stdio library for the same input stream.
+
+
        RETURN VALUES
+
               fgetc(), getc() and getchar() return the character read as
+       an  unsigned  char cast to an int or EOF on end of file or
+       error.
+
+       gets() and fgets() return s on success, and NULL on end of
+       file or error.
+
+       ungetc() returns c on success, or EOF on error.

+
        BUGS
+
               Because  it is impossible to tell without knowing the data
+       in advance how  many  characters  gets()  will  read,  and
+       because  gets() will continue to store characters past the
+       end of the buffer, it is extremely dangerous to  use.   It
+       has  been  used  to  break computer security.  Use fgets()
+       instead.
+
+       It is not advisable to mix calls to input  functions  from
+       the stdio library with low - level calls to read() for the
+       file descriptor associated  with  the  input  stream;  the
+       results  will  be undefined and very probably not what you
+       want.

+
+
        DESCRIPTION
+
               getgroups
+              Up  to  size  supplemental  groups  are returned in
+              list.  If size is zero, list is not  modified,  but
+              the  total  number  of  supplemental groups for the
+              process is returned.
+
+       setgroups
+              Sets the supplemental groups for the process.  Only
+              the super-user may use this function.
+
+
        RETURN VALUE
+
               getgroups
+              On  success, the number of groups stored in list is
+              returned (if size is zero, however, the  number  of
+              supplemental  group IDs associated with the process
+              is returned).  On error, -1 is returned, and  errno
+              is set appropriately.
+
+       setgroups
+              On  success,  zero  is  returned.   On error, -1 is
+              returned, and errno is set appropriately.
+
+
        ERRORS
+
               EFAULT list has an invalid address.
+
+       EPERM  For setgroups, the user is not the super-user.
+
+       EINVAL For setgroups, gidsetsize is greater  than  NGROUPS
+              (32 for Linux 0.99.11).
+
+
        CONFORMING TO
+
               getgroups conforms to POSIX.1 (and is present in BSD 4.3).
+       Since setgroups requires  privilege,  it  is  not  covered
+       under POSIX.1.
+
+
        BUGS
+
               The __USE_BSD flag probably shouldn't be required for set-
+       groups.

+
+
        DESCRIPTION
+
               These  functions  are used to access or to change the host
+       name of the current processor.
+
+
        RETURN VALUE
+
               On success, zero is returned.  On error, -1  is  returned,
+       and errno is set appropriately.
+
+
        ERRORS
+
               EINVAL len  is negative or, for sethostname, len is larger
+              than the maximum allowed size, or, for  gethostname
+              on Linux/i386, len is smaller than the actual size.
+
+       EPERM  For sethostname, the caller was not the  superuser.
+
+       EFAULT name is an invalid address.
+
+
        CONFORMING TO
+
               POSIX.1  does  not  define  these  functions,  but ISO/IEC
+       9945-1:1990 mentions them in B.4.4.1.
+
+
        BUGS
+
               Some other  implementations  of  gethostname  successfully
+       return len bytes even if name is longer.  Linux/Alpha com-
+       plies with this behaviour.  Linux/i386,  however,  returns
+       EINVAL in this case (as of DLL 4.6.27 libraries).
+
+
        NOTES
+
               Under  Linux/Alpha,  gethostname  is a system call.  Under
+       Linux/i386, gethostname  is  implemented  at  the  library
+       level by calling uname(2).

        NAME
+
               getopt - Read command line options
+
+
        SYNOPSIS
+
               #include <unistd.h>
+
+       int getopt(int argc, char * const argv[],
+                  const char *optstring);
+
+       extern char *optarg;
+       extern int optind, opterr, optopt;
+
+       #include <getopt.h>
+
+       int getopt_long(int argc, char * const argv[],
+                       const char *shortopts,
+                       const struct option *longopts, int longind);
+
+
        DESCRIPTION
+
               The  getopt()  function parses the command line arguments.
+       Its arguments argc and argv are  the  argument  count  and
+       array  as passed to the main() function on program invoca-
+       tion.  optstring is a list of available option characters.
+       If  such  a  character  is followed by a colon, the option
+       takes an argument, which is placed in optarg.
+
+       The external variable optind is  the  index  of  the  next
+       array  element  of argv[] to be processed; it communicates
+       from one call of getopt() to the  next  which  element  to
+       process.
+
+       The getopt_long() function works like getopt() except that
+       it also accepts long options, started out by  two  dashes.
+       If these take values, it is either in the form --arg=value
+       or --arg value.  It takes the  additional  arguments  lon-
+       gopts  which is a pointer to the first element of an array
+       of struct option declared in <getopt.h> as
+
+          struct option {
+              const char *name;
+              int has_arg;
+              int *flag;
+              int val;
+          };
+
+          The meaning of the different fields are:
+
+       name   is the name of the long option.
+
+       has_arg
+              is a boolean value which should be set  to  nonzero
+              if the long option takes a value.
+
+       flag   determines   the   return  value  if  getopt_long()
+
+
+
+

        GETOPT(3)           Linux Programmer's Manual           GETOPT(3)
+
        
+
+              returns a value for a long option; if  it  is  non-
+              zero,  zero is returned as a function value, other-
+              wise val.
+
+       val    determines the value to return if flag is zero.
+
+       The last element of  the  array  has  to  be  filled  with
+       zeroes.
+
+       The  option_index  points  to the index of the long option
+       relative to longopts.
+
+
        RETURN VALUE
+
               The getopt() function returns the option character if  the
+       option  was found successfully, ':' if there was a missing
+       parameter for one of  the  options,  '?'  for  an  unknown
+       option character and -1 for the end of the option list.
+
+
        EXAMPLE
+
               The  following  example  program,  from  the  source code,
+       illustrates the use of getopt_long() with most of its fea-
+       tures.
+
+       #include <stdio.h>
+
+       int
+       main (argc, argv)
+            int argc;
+            char **argv;
+       {
+         int c;
+         int digit_optind = 0;
+
+         while (1)
+           {
+             int this_option_optind = optind ? optind : 1;
+             int option_index = 0;
+             static struct option long_options[] =
+             {
+            {"add", 1, 0, 0},
+            {"append", 0, 0, 0},
+            {"delete", 1, 0, 0},
+            {"verbose", 0, 0, 0},
+            {"create", 1, 0, 'c'},
+            {"file", 1, 0, 0},
+            {0, 0, 0, 0}
+             };
+
+             c = getopt_long (argc, argv, "abc:d:012",
+                        long_options, &option_index);
+             if (c == -1)

+
+
        NAME
+
               setpgid, getpgid, setpgrp, getpgrp - set/get process group
+
+
        SYNOPSIS
+
               #include <unistd.h>
+
+       int setpgid(pid_t pid, pid_t pgid);
+       pid_t getpgid(pid_t pid);
+       int setpgrp(void);
+       pid_t getpgrp(void);
+
+
        DESCRIPTION
+
               setpgid sets the process group ID of the process specified
+       by  pid  to  pgid.   If pid is zero, the process ID of the
+       current process is used.  If pgid is zero, the process  ID
+       of the process specified by pid is used.
+
+       getpgid returns the process group ID of the process speci-
+       fied by pid.  If pid is zero, the process ID of  the  cur-
+       rent process is used.
+
+       In  the  Linux  DLL  4.4.1  library,  setpgrp simply calls
+       setpgid(0,0).
+
+       getpgrp is equivalent to getpgid(0).
+
+       Process groups are used for distribution of  signals,  and
+       by  terminals  to arbitrate requests for their input: pro-
+       cesses that have the same process group  as  the  terminal
+       are  foreground and may read, while others will block with
+       a signal if they attempt to read.
+
+       These calls are thus used by programs such  as  csh(1)  to
+       create  process  groups  in implementing job control.  The
+       TIOCGPGRP and TIOCSPGRP calls described in termios(4)  are
+       used to get/set the process group of the control terminal.
+
+
        RETURN VALUE
+
               On success, setpgid and setpgrp return zero.  On error, -1
+       is returned, and errno is set appropriately.
+
+       getpgid  returns a process group on success.  On error, -1
+       is returned, and errno is set appropriately.
+
+       getpgrp always returns the current process group.
+
+
        ERRORS
+
               EINVAL  pgid is less than 0.
+
+       EPERM   Various permission violations.
+
+       ESRCH   pid does not match any process.

+
+
        NAME
+
               getpwent, setpwent, endpwent - get password file entry
+
+
        SYNOPSIS
+
               #include <pwd.h>
+       #include <sys/types.h>
+
+       struct passwd *getpwent(void);
+
+       void setpwent(void);
+
+       void endpwent(void);
+
+
        DESCRIPTION
+
               The  getpwent()  function returns a pointer to a structure
+       containing  the  broken  out  fields  of   a   line   from
+       /etc/passwd.   The  first time it is called it returns the
+       first entry; thereafter, it returns successive entries.
+
+       The setpwent() function rewinds the file  pointer  to  the
+       beginning of the /etc/passwd file.
+
+       The endpwent() function closes the /etc/passwd file.
+
+       The passwd structure is defined in <pwd.h> as follows:
+
+              struct passwd {
+                      char    *pw_name;       /* user name */
+                      char    *pw_passwd;     /* user password */
+                      uid_t   pw_uid;         /* user id */
+                      gid_t   pw_gid;         /* group id */
+                      char    *pw_gecos;      /* real name */
+                      char    *pw_dir;        /* home directory */
+                      char    *pw_shell;      /* shell program */
+              };
+
+
        RETURN VALUE
+
               The  getpwent()  function returns the passwd structure, or
+       NULL if there are no more entries or an error occurs.
+
+
        ERRORS

               ENOMEM Insufficient memory to allocate passwd structure.

        NAME
+
               getpwnam, getpwuid - get password file entry
+
+
        SYNOPSIS
+
               #include <pwd.h>
+       #include <sys/types.h>
+
+       struct passwd *getpwnam(const char * name);
+
+       struct passwd *getpwuid(uid_t uid);
+
+
        DESCRIPTION
+
               The  getpwnam()  function returns a pointer to a structure
+       containing  the  broken  out  fields  of   a   line   from
+       /etc/passwd for the entry that matches the user name name.
+
+       The getpwuid() function returns a pointer to  a  structure
+       containing   the   broken   out  fields  of  a  line  from
+       /etc/passwd for the entry that matches the user uid uid.
+
+       The passwd structure is defined in <pwd.h> as follows:
+
+              struct passwd {
+                      char    *pw_name;       /* user name */
+                      char    *pw_passwd;     /* user password */
+                      uid_t   pw_uid;         /* user id */
+                      gid_t   pw_gid;         /* group id */
+                      char    *pw_gecos;      /* real name */
+                      char    *pw_dir;        /* home directory */
+                      char    *pw_shell;      /* shell program */
+              };
+
+
        RETURN VALUE
+
               The getpwnam() and getpwuid() functions return the  passwd
+       structure,  or  NULL if the matching entry is not found or
+       an error occurs.

        GETS(3)             Linux Programmer's Manual             GETS(3)
+
        
+
+
        NAME
+
               fgetc, fgets, getc, getchar, gets, ungetc - input of char-
+       acters and strings
+
+
        SYNOPSIS
+
               #include <stdio.h>
+
+       int fgetc(FILE *stream);
+       char *fgets(char *s, int size, FILE *stream);
+       int getc(FILE *stream);
+       int getchar(void);
+       char *gets(char *s);
+       int ungetc(int c, FILE *stream);
+
+
        DESCRIPTION
+
               fgetc() reads the next character from stream  and  returns
+       it  as  an  unsigned char cast to an int, or EOF on end of
+       file or error.
+
+       getc() is equivalent to fgetc()  except  that  it  may  be
+       implemented  as  a  macro which evaluates stream more than
+       once.
+
+       getchar() is equivalent to getc(stdin).
+
+       gets() reads a line from stdin into the buffer pointed  to
+       by  s  until either a terminating newline or EOF, which it
+       replaces with '\0'.  No check for buffer overrun  is  per-
+       formed (see BUGS below).
+
+       fgets()  reads  in at most one less than n characters from
+       stream and stores them into the buffer pointed  to  by  s.
+       Reading  stops after an EOF or a newline.  If a newline is
+       read, it is stored into the  buffer.   A  '\0'  is  stored
+       after the last character in the buffer.
+
+       ungetc()  pushes  c back to stream, cast to unsigned char,
+       where it is  available  for  subsequent  read  operations.
+       Pushed  -  back  characters  will  be  returned in reverse
+       order; only one pushback is guaranteed.
+
+       Calls to the functions described here can  be  mixed  with
+       each  other  and  with calls to other input functions from
+       the stdio library for the same input stream.
+
+
        RETURN VALUES
+
               fgetc(), getc() and getchar() return the character read as
+       an  unsigned  char cast to an int or EOF on end of file or
+       error.
+
+       gets() and fgets() return s on success, and NULL on end of
+       file or error.
+
+       ungetc() returns c on success, or EOF on error.

        BUGS
+
               Because  it is impossible to tell without knowing the data
+       in advance how  many  characters  gets()  will  read,  and
+       because  gets() will continue to store characters past the
+       end of the buffer, it is extremely dangerous to  use.   It
+       has  been  used  to  break computer security.  Use fgets()
+       instead.
+
+       It is not advisable to mix calls to input  functions  from
+       the stdio library with low - level calls to read() for the
+       file descriptor associated  with  the  input  stream;  the
+       results  will  be undefined and very probably not what you
+       want.

+
+
        NAME
+
               ioctl - control device
+
+
        SYNOPSIS
+
               #include <sys/ioctl.h>
+
+       int ioctl(int d, int request, ...)
+
+       [The  "third"  argument  is  traditionally char *argp, and
+       will be so named for this discussion.]
+
+
        DESCRIPTION
+
               The  ioctl  function  manipulates  the  underlying  device
+       parameters  of special files.  In particular, many operat-
+       ing characteristics of character special files (e.g.  ter-
+       minals)  may be controlled with ioctl requests.  The argu-
+       ment d must be an open file descriptor.
+
+       An ioctl request has encoded in it whether the argument is

+
        NAME
+
               link - make a new name for a file
+
+
        SYNOPSIS
+
               #include <unistd.h>
+
+       int link(const char *oldpath, const char *newpath);
+
+
        DESCRIPTION
+
               link  creates a new link (also known as a hard link) to an
+       existing file.
+
+       If newpath exists it will not be overwritten.
+
+       This new name may be used exactly as the old one  for  any
+       operation;  both names refer to the same file (and so have
+       the same permissions and ownership) and it  is  impossible
+       to tell which name was the `original'.
+
+
        RETURN VALUE
+
               On  success,  zero is returned.  On error, -1 is returned,
+       and errno is set appropriately.
+
+
        ERRORS
+
               EXDEV   oldpath and newpath are not on the  same  filesys-
+               tem.
+
+       EPERM   The filesystem containing oldpath and newpath does
+               not support the creation of hard links.
+
+       EFAULT  oldpath or newpath points outside your  accessible
+               address space.
+
+       EACCES  Write  access  to the directory containing newpath
+               is not allowed for the process's effective uid, or
+               one  of  the directories in oldpath or newpath did
+               not allow search (execute) permission.
+
+       ENAMETOOLONG
+               oldpath or newpath was too long.
+
+       ENOENT  A directory component in oldpath  or  newpath does
+               not exist or is a dangling symbolic link.
+
+       ENOTDIR A component used as a directory in oldpath or new-
+               path is not, in fact, a directory.
+
+       ENOMEM  Insufficient kernel memory was available.
+
+       EROFS   The file is on a read-only filesystem.

+               maximum number of links to it.
+
+       ELOOP   oldpath  or newpath contains a reference to a cir-
+               cular symbolic link,  ie  a  symbolic  link  whose
+               expansion contains a reference to itself.
+
+       ENOSPC  The device containing the file has no room for the
+               new directory entry.
+
+       EPERM   oldpath is the .  or  ..  entry of a directory.
+
+
        NOTES
+
               Hard links, as created by link, cannot  span  filesystems.

        BUGS
+
               On  NFS file systems, the return code may be wrong in case
+       the NFS server performs the link creation and dies  before
+       it  can  say  so.  Use stat(2) to find out if the link got
+       created.

        LONGJMP(3)              Library functions              LONGJMP(3)
+
        
+
+
        NAME
+
               longjmp - non-local jump to a saved stack context
+
+
        SYNOPSIS
+
               #include <setjmp.h>
+
+       void longjmp(jmp_buf env, int val);
+
+
        DESCRIPTION
+
               longjmp() and setjmp(3) are useful for dealing with errors
+       and interrupts encountered in a low-level subroutine of  a
+       program.   longjmp() restores the environment saved by the
+       last call of setjmp() with the corresponding env argument.
+       After  longjmp() is completed, program execution continues
+       as if the corresponding call of setjmp() had just returned
+       the  value  val.  longjmp() cannot cause 0 to be returned.
+       If longjmp is invoked with a second argument of 0, 1  will
+       be returned instead.
+
+
        RETURN VALUE
+
               This function never returns.
+
+
        CONFORMING TO
+
               POSIX
+
+
        NOTES
+
               POSIX  does  not  specify  if  the  signal context will be
+       restored or not.  If  you  want  to  save  restore  signal
+       masks,  use siglongjmp(3) longjmp() makes programs hard to
+       understand  and  maintain.   If  possible  an  alternative
+       should be used.

+       directive  whence.   The  argument  fildes must be an open
+       file  descriptor.   Lseek  repositions  the  file  pointer
+       fildes as follows:
+
+              If  whence is SEEK_SET, the offset is set to offset
+              bytes.
+
+              If whence is SEEK_CUR, the offset  is  set  to  its
+              current location plus offset bytes.
+
+              If  whence  is  SEEK_END,  the offset is set to the
+              size of the file plus offset bytes.
+
+       The lseek function allows the file offset to be set beyond
+       the  end  of the existing end-of-file of the file. If data
+       is later written at this point, subsequent  reads  of  the
+       data in the gap return bytes of zeros (until data is actu-
+       ally written into the gap).
+
+       Some devices are incapable of seeking.  The value  of  the
+       pointer associated with such a device is undefined.
+
+
        RETURN VALUES
+
               Upon  successful  completion,  lseek returns the resulting
+       offset location as measured in bytes from the beginning of
+       the  file.  Otherwise, a value of -1 is returned and errno
+       is set to indicate the error.
+
+
        ERRORS
+
               EBADF  Fildes is not an open file descriptor.
+
+       ESPIPE Fildes is associated with a pipe, socket, or  FIFO.
+
+       EINVAL Whence is not a proper value.

        BUGS
+
               This  document's  use  of whence is incorrect English, but
+       maintained for historical reasons.

        NAME
+
               mblen - determine the number of bytes in a character
+
+
        SYNOPSIS
+
               #include <stdlib.h>
+
+       int mblen(const char *s, size_t n);
+
+
        DESCRIPTION
+
               The mblen() function scans the first n bytes of the string
+       s and returns the number of bytes  in  a  character.   The
+       mblen() function is equivalent to
+
+              mbtowc((wchat_t *)0, s, n);
+
+       except  that  the  shift state of the mbtowc() function is
+       not affected.
+
+
        RETURN VALUE
+
               The mblen() returns the number of bytes in a character  or
+       -1 if the character is invalid or 0 if s is a NULL string.

+
        DESCRIPTION
+
               The  memchr() function scans the first n bytes of the mem-
+       ory area pointed to by s for the character c.   The  first
+       byte  to  match  c  (interpreted as an unsigned character)
+       stops the operation.
+
+
        RETURN VALUE
+
               The memchr() function returns a pointer  to  the  matching
+       byte  or NULL if the character does not occur in the given
+       memory area.

+
+
        NAME
+
               mkdir - create a directory
+
+
        SYNOPSIS
+
               #include <sys/types.h>
+       #include <fcntl.h>
+       #include <unistd.h>
+
+       int mkdir(const char *pathname, mode_t mode);
+
+
        DESCRIPTION
+
               mkdir attempts to create a directory named pathname.
+
+       mode  specifies  the permissions to use. It is modified by
+       the process's umask in the usual way: the  permissions  of
+       the created file are (mode & ~umask).
+
+       The newly created directory will be owned by the effective
+       uid of the process.  If the directory containing the  file
+       has  the  set  group  id  bit set, or if the filesystem is
+       mounted with BSD group semantics, the new  directory  will
+       inherit  the group ownership from its parent; otherwise it
+       will be owned by the effective gid of the process.
+
+       If the parent directory has the set group id bit set  then
+       so will the newly created directory.
+
+
+
        RETURN VALUE
+
               mkdir  returns zero on success, or -1 if an error occurred
+       (in which case, errno is set appropriately).
+
+
        ERRORS
+
               EEXIST pathname  already  exists  (not  necessarily  as  a
+              directory).
+
+       EFAULT pathname  points  outside  your  accessible address
+              space.
+
+       EACCES The parent directory does not allow  write  permis-
+              sion  to  the process, or one of the directories in
+              pathname did not allow search (execute) permission.
+
+       ENAMETOOLONG
+              pathname was too long.
+
+       ENOENT A directory component in pathname does not exist or
+              is a dangling symbolic link.
+
+       ENOTDIR
+              A component used as a directory in pathname is not,
+              in fact, a directory.
+
+       ENOMEM Insufficient kernel memory was available.

+
+       EROFS  pathname refers to a file on a read-only filesystem
+              and write access was requested.
+
+       ELOOP  pathname contains a reference to  a  circular  sym-
+              bolic link, ie a symbolic link whose expansion con-
+              tains a reference to itself.
+
+       ENOSPC The device containing pathname has no room for  the
+              new  directory.  ENOSPC The new directory cannot be
+              created because the user's disk quota is exhausted.

        BUGS
+
               In some older versions of Linux (for example, 0.99pl7) all
+       the normal filesystems sometime allow the creation of  two
+       files  in  the  same  directory  with the same name.  This
+       occurs only rarely and only on a  heavily  loaded  system.
+       It  is  believed  that  this  bug  was  fixed in the Minix
+       filesystem in Linux 0.99pl8 pre-release; and it  is  hoped
+       that  it was fixed in the other filesystems shortly after-
+       wards.
+
+       There are many infelicities  in  the  protocol  underlying
+       NFS.

+
+       double modf(double x, double *iptr);
+
+
        DESCRIPTION
+
               The modf() function breaks the argument x into an integral
+       part  and  a  fractional  part, each of which has the same

+            manpage.
+
+       Use Perl from Perl?
+            Read about the do entry in the perlfunc manpage and
+            the eval entry in the perlfunc manpage and the use
+            entry in the perlmod manpage and the require entry in

+
+       Use C from C?
+            Rethink your design.

+
        
+
+       What's that, you ask?  Perl is itself written in C; the
+       perl library is the collection of compiled C programs that
+       were used to create your perl executable (/usr/bin/perl or
+       equivalent).  (Corollary: you can't use Perl from your C
+       program unless Perl has been compiled on your machine, or
+       installed properly--that's why you shouldn't blithely copy
+       Perl executables from machine to machine without also
+       copying the lib directory.)
+
+       Your C program will--usually--allocate, "run", and
+       deallocate a PerlInterpreter object, which is defined in
+       the perl library.
+
+       If your copy of Perl is recent enough to contain this
+       documentation (5.002 or later), then the perl library (and
+       EXTERN.h and perl.h, which you'll also need) will reside
+       in a directory resembling this:
+
+           /usr/local/lib/perl5/your_architecture_here/CORE
+
+       or perhaps just
+
+           /usr/local/lib/perl5/CORE
+
+       or maybe something like
+
+           /usr/opt/perl5/CORE
+
+       Execute this statement for a hint about where to find
+       CORE:
+
+           perl -e 'use Config; print $Config{archlib}'
+
+       Here's how you might compile the example in the next
+       section, the section on Adding a Perl interpreter to your
+       C program, on a DEC Alpha running the OSF operating

+
+       Adding a Perl interpreter to youur C program
+
+       In a sense, perl (the C program) is a good example of
+       embedding Perl (the language), so I'll demonstrate
+       embedding with miniperlmain.c, from the source
+       distribution.  Here's a bastardized, non-portable version
+       of miniperlmain.c containing the essentials of embedding:
+
+           #include <stdio.h>
+           #include <EXTERN.h>               /* from the Perl distribution     */
+           #include <perl.h>                 /* from the Perl distribution     */
+
+           static PerlInterpreter *my_perl;  /***    The Perl interpreter    ***/
+
+           int main(int argc, char **argv, char **env)
+           {
+               my_perl = perl_alloc();
+               perl_construct(my_perl);
+               perl_parse(my_perl, NULL, argc, argv, env);
+               perl_run(my_perl);
+               perl_destruct(my_perl);
+               perl_free(my_perl);
+           }
+
+       Now compile this program (I'll call it interp.c) into an
+       executable:
+
+           % cc -o interp interp.c -L/usr/local/lib/perl5/alpha-dec_osf/CORE
+           -I/usr/local/lib/perl5/alpha-dec_osf/CORE -lperl -lm
+
+       After a successful compilation, you'll be able to use
+       interp just like perl itself:
+
+           % interp
+           print "Pretty Good Perl \n";
+           print "10890 - 9801 is ", 10890 - 9801;
+           <CTRL-D>
+           Pretty Good Perl
+           10890 - 9801 is 1089
+
+       or
+
+           % interp -e 'printf("%x", 3735928559)'
+           deadbeef
+
+       You can also read and execute Perl statements from a file
+       while in the midst of your C program, by placing the
+       filename in argv[1] before calling perl_run().
+
+       Calling a Perl subroutine from yyour C program
+
+       To call individual Perl subroutines, you'll need to remove
+       the call to perl_run() and replace it with a call to
+       perl_call_argv().

+
+       That's shown below, in a program I'll call showtime.c.
+
+           #include <stdio.h>
+           #include <EXTERN.h>
+           #include <perl.h>
+
+           static PerlInterpreter *my_perl;
+
+           int main(int argc, char **argv, char **env)
+           {
+               my_perl = perl_alloc();
+               perl_construct(my_perl);
+
+               perl_parse(my_perl, NULL, argc, argv, env);
+
+                                            /*** This replaces perl_run() ***/
+               perl_call_argv("showtime", G_DISCARD | G_NOARGS, argv);
+               perl_destruct(my_perl);
+               perl_free(my_perl);
+           }
+
+       where showtime is a Perl subroutine that takes no
+       arguments (that's the G_NOARGS) and for which I'll ignore
+       the return value (that's the G_DISCARD).  Those flags, and
+       others, are discussed in the perlcall manpage.
+
+       I'll define the showtime subroutine in a file called
+       showtime.pl:
+
+           print "I shan't be printed.";
+
+           sub showtime {
+               print time;
+           }
+
+       Simple enough.  Now compile and run:
+
+           % cc -o showtime showtime.c -L/usr/local/lib/perl5/alpha-dec_osf/CORE
+           -I/usr/local/lib/perl5/alpha-dec_osf/CORE -lperl -lm
+
+           % showtime showtime.pl
+           818284590
+
+       yielding the number of seconds that elapsed between
+       January 1, 1970 (the beginning of the UNIX epoch), and the
+       moment I began writing this sentence.
+
+       If you want to pass some arguments to the Perl subroutine,
+       or you want to access the return value, you'll need to
+       manipulate the Perl stack, demonstrated in the last
+       section of this document: the section on Fiddling with the
+       Perl stack from your C program

+
+       Evaluating a Perl statement fr
        om your C program
+
        
+       NOTE: This section, and the next, employ some very brittle
+       techniques for evaluting strings of Perl code.  Perl 5.002
+       contains some nifty features that enable A Better Way
+       (such as with the perl_eval_sv entry in the perlguts
+       manpage).  Look for updates to this document soon.
+
+       One way to evaluate a Perl string is to define a function
+       (we'll call ours perl_eval()) that wraps around Perl's the
+       eval entry in the perlfunc manpage.
+
+       Arguably, this is the only routine you'll ever need to
+       execute snippets of Perl code from within your C program.
+       Your string can be as long as you wish; it can contain
+       multiple statements; it can use the require entry in the
+       perlmod manpage or the do entry in the perlfunc manpage to
+       include external Perl files.
+
+       Our perl_eval() lets us evaluate individual Perl strings,
+       and then extract variables for coercion into C types.  The
+       following program, string.c, executes three Perl strings,
+       extracting an int from the first, a float from the second,
+       and a char * from the third.

+
+       All of those strange functions with sv in their names help
+       convert Perl scalars to C types.  They're described in the
+       perlguts manpage.
+
+       If you compile and run string.c, you'll see the results of
+       using SvIV() to create an int, SvNV() to create a float,
+       and SvPV() to create a string:
+
+          a = 9
+          a = 9.859600
+          a = Just Another Perl Hacker

+       Performing Perl pattern matche
        s and substitutions from
+
               your C program
+
+       Our perl_eval() lets us evaluate strings of Perl code, so
+       we can define some functions that use it to "specialize"
+       in matches and substitutions: match(), substitute(), and
+       matches().
+
+          char match(char *string, char *pattern);
+
+       Given a string and a pattern (e.g. "m/clasp/" or
+       "/\b\w*\b/", which in your program might be represented as
+       "/\\b\\w*\\b/"), returns 1 if the string matches the
+       pattern and 0 otherwise.
+
+          int substitute(char *string[], char *pattern);
+
+       Given a pointer to a string and an "=~" operation (e.g.
+       "s/bob/robert/g" or "tr[A-Z][a-z]"), modifies the string
+       according to the operation, returning the number of
+       substitutions made.
+
+          int matches(char *string, char *pattern, char **matches[]);
+
+       Given a string, a pattern, and a pointer to an empty array
+       of strings, evaluates $string =~ $pattern in an array
+       context, and fills in matches with the array elements
+       (allocating memory as it does so), returning the number of
+       matches found.

+       =head2 Fiddling with the Perl stack from your C program
+
+       When trying to explain stacks, most computer science
+       textbooks mumble something about spring-loaded columns of
+       cafeteria plates: the last thing you pushed on the stack
+       is the first thing you pop off.  That'll do for our
+       purposes: your C program will push some arguments onto
+       "the Perl stack", shut its eyes while some magic happens,
+       and then pop the results--the return value of your Perl
+
+
+
+

+
+       subroutine--off the stack.
+
+       First you'll need to know how to convert between C types
+       and Perl types, with newSViv() and sv_setnv() and newAV()
+       and all their friends.  They're described in the perlguts
+       manpage.
+
+       Then you'll need to know how to manipulate the Perl stack.
+       That's described in the perlcall manpage.
+
+       Once you've understood those, embedding Perl in C is easy.
+
+       Since C has no built-in function for integer
+       exponentiation, let's make Perl's ** operator available to
+       it (this is less useful than it sounds, since Perl
+       implements ** with C's pow() function).  First I'll create
+       a stub exponentiation function in power.pl:
+
+           sub expo {
+               my ($a, $b) = @_;
+               return $a ** $b;
+           }
+
+       Now I'll create a C program, power.c, with a function
+       PerlPower() that contains all the perlguts necessary to
+       push the two arguments into expo() and to pop the return
+       value out.  Take a deep breath...

        MORAL
+
               You can sometimes write faster code in C, but you can
+       always write code faster in Perl.  Since you can use each
+       from the other, combine them as you wish.

+       void perror(const char *s);
+
+
        DESCRIPTION
+
               perror  produces  a  message on the standard error output,
+       describing the last error encountered during a call  to  a
+       system  or  library  function.   The  argument string s is
+       printed first, then a colon and a blank, then the  message
+       and  a  new-line.   To be of most use, the argument string
+       should include the name of the program that  incurred  the
+       error.   The error number is taken from the external vari-
+       able errno, which is set when errors occur but not cleared
+       when non-erroneous calls are made.

        NAME
+
               printf,  fprintf,  sprintf,  vprintf, vfprintf, vsprintf -
+       formatted output conversion
+
+
        SYNOPSIS
+
               #include <stdio.h>
+
+       int printf( const char *format, ...);
+       int fprintf( FILE *stream, const char *format, ...);
+       int sprintf( char *str, const char *format, ...);

+       int vprintf( const char *format, va_list ap);
+       int vfprintf( FILE *stream, const  char  *format,  va_list
+       ap);
+       int vsprintf( char *str, char *format, va_list ap);
+
+
        DESCRIPTION
+
               The  printf  family of functions produces output according
+       to a format as described below.  Printf and vprintf  write
+       output  to stdout, the standard output stream; fprintf and
+       vfprintf write output to the given output stream; sprintf,
+       and  vsprintf  write  to  the character string str.  These
+       functions write the output under the control of  a  format
+       string  that  specifies how subsequent arguments (or argu-
+       ments accessed via the variable-length argument facilities
+       of  stdarg(3)  are  converted for output.  These functions
+       return the number of characters printed (not including the
+       trailing `\0' used to end output to strings).
+
+       The  format string is composed of zero or more directives:
+       ordinary characters (not %), which are copied unchanged to
+       the  output stream; and conversion specifications, each of
+       which results in fetching zero or  more  subsequent  argu-
+       ments.  Each conversion specification is introduced by the
+       character  %.   The  arguments  must  correspond  properly
+       (after  type  promotion)  with  the  conversion specifier.
+       After the %, the following appear in sequence:
+
+       o      Zero or more of the following flags:
+
+              #      specifying that the  value  should  be  con-
+                     verted  to an ``alternate form''.  For c, d,
+                     i, n, p, s, and u conversions,  this  option
+                     has  no effect.  For o conversions, the pre-
+                     cision of the number is increased  to  force
+                     the  first character of the output string to
+                     a zero (except if a zero  value  is  printed
+                     with  an explicit precision of zero).  For x
+                     and X conversions, a non-zero result has the
+                     string  `0x'  (or  `0X'  for  X conversions)
+                     prepended to it.  For e, E, f, g, and G con-
+                     versions,  the  result will always contain a

+                     decimal point, even if no digits  follow  it
+                     (normally,  a  decimal  point appears in the
+                     results of those conversions only if a digit
+                     follows).  For g and G conversions, trailing
+                     zeros are not removed  from  the  result  as
+                     they would otherwise be.
+
+              0      specifying  zero  padding.   For all conver-
+                     sions  except  n,  the  converted  value  is
+                     padded  on  the  left with zeros rather than
+                     blanks.  If a  precision  is  given  with  a
+                     numeric  conversion  (d,  i, o, u, i, x, and
+                     X), the 0 flag is ignored.
+
+              -      (a negative field width flag) indicates  the
+                     converted  value  is  to be left adjusted on
+                     the field boundary.  Except  for  n  conver-
+                     sions,  the converted value is padded on the
+                     right with blanks, rather than on  the  left
+                     with  blanks or zeros.  A - overrides a 0 if
+                     both are given.
+
+                     (a space) specifying that a blank should  be
+                     left  before a positive number produced by a
+                     signed conversion (d, e, E, f, g, G, or  i).
+
+              +      specifying  that  a  sign  always  be placed
+                     before a number produced by a signed conver-
+                     sion.   A  +  overrides  a space if both are
+                     used.
+
+       o      An optional decimal digit string specifying a mini-
+              mum  field width.  If the converted value has fewer
+              characters than the field width, it will be  padded
+              with  spaces  on  the  left (or right, if the left-
+              adjustment flag has been given)  to  fill  out  the
+              field width.
+
+       o      An  optional  precision,  in  the  form of a period
+              (`.')  followed by an optional  digit  string.   If
+              the digit string is omitted, the precision is taken
+              as zero.  This gives the minimum number  of  digits
+              to appear for d, i, o, u, x, and X conversions, the
+              number of digits to appear after the  decimal-point
+              for  e, E, and f conversions, the maximum number of
+              significant digits for g and G conversions, or  the
+              maximum  number  of characters to be printed from a
+              string for s conversions.
+
+       o      The optional character h, specifying that a follow-
+              ing d, i, o, u, x, or X conversion corresponds to a
+              short int or unsigned short int argument, or that a
+              following  n conversion corresponds to a pointer to
+              a short int argument.

+
+       o      The optional character l (ell)  specifying  that  a
+              following d, i, o, u, x, or X conversion applies to
+              a pointer to a long int or unsigned long int  argu-
+              ment,  or that a following n conversion corresponds
+              to a pointer to a long int argument.
+
+       o      The character L specifying that a following  e,  E,
+              f,  g, or G conversion corresponds to a long double
+              argument.
+
+       o      A character that specifies the type  of  conversion
+              to be applied.
+
+       A  field  width or precision, or both, may be indicated by
+       an asterisk `*' instead of a digit string.  In this  case,
+       an  int argument supplies the field width or precision.  A
+       negative field width is treated as a left adjustment  flag
+       followed  by  a positive field width; a negative precision
+       is treated as though it were missing.
+
+       The conversion specifiers and their meanings are:
+
+       diouxX The int (or appropriate variant) argument  is  con-
+              verted  to signed decimal (d and i), unsigned octal
+              (o, unsigned decimal (u, or unsigned hexadecimal (x
+              and X) notation.  The letters abcdef are used for x
+              conversions; the letters ABCDEF are used for X con-
+              versions.  The precision, if any, gives the minimum
+              number of digits that must appear; if the converted
+              value  requires  fewer  digits, it is padded on the
+              left with zeros.
+
+       DOU    The long int argument is converted to signed  deci-
+              mal, unsigned octal, or unsigned decimal, as if the
+              format had been ld, lo, or lu respectively.   These
+              conversion  characters  are  deprecated,  and  will
+              eventually disappear.
+
+       eE     The double argument is rounded and converted in the
+              style  [-]d.dddedd  where there is one digit before
+              the decimal-point character and the number of  dig-
+              its after it is equal to the precision; if the pre-
+              cision is missing, it is taken as 6; if the  preci-
+              sion  is  zero, no decimal-point character appears.
+              An E conversion uses the letter E (rather  than  e)
+              to  introduce  the  exponent.   The exponent always
+              contains at least two digits; if the value is zero,
+              the exponent is 00.
+
+       f      The  double  argument  is  rounded and converted to
+              decimal notation in the style [-]ddd.ddd, where the
+              number  of digits after the decimal-point character
+              is equal to the precision  specification.   If  the
+              precision  is  missing,  it  is  taken as 6; if the

+
        
+
+              precision  is  explicitly  zero,  no  decimal-point
+              character  appears.  If a decimal point appears, at
+              least one digit appears before it.
+
+       g      The double argument is converted in style  f  or  e
+              (or  E for G conversions).  The precision specifies
+              the number of significant digits.  If the precision
+              is missing, 6 digits are given; if the precision is
+              zero, it is treated as 1.  Style e is used  if  the
+              exponent  from  its  conversion  is less than -4 or
+              greater than or equal to the  precision.   Trailing
+              zeros  are  removed from the fractional part of the
+              result; a decimal point appears only if it is  fol-
+              lowed by at least one digit.
+
+       c      The  int argument is converted to an unsigned char,
+              and the resulting character is written.
+
+       s      The ``char *'' argument is expected to be a pointer
+              to  an  array  of  character  type  (pointer  to  a
+              string).  Characters from the array are written  up
+              to (but not including) a terminating NUL character;
+              if a precision is specified, no more than the  num-
+              ber  specified  are  written.   If  a  precision is
+              given, no null character need be  present;  if  the
+              precision  is not specified, or is greater than the
+              size of the array, the array must contain a  termi-
+              nating NUL character.
+
+       p      The  ``void *'' pointer argument is printed in hex-
+              adecimal (as if by %#x or %#lx).
+
+       n      The number of characters written so far  is  stored
+              into  the  integer  indicated  by the ``int *'' (or
+              variant) pointer argument.   No  argument  is  con-
+              verted.
+
+       %      A  `%'  is  written.  No argument is converted. The
+              complete conversion specification is `%%'.
+
+       In no case does a non-existent or small field width  cause
+       truncation  of  a  field; if the result of a conversion is
+       wider than the field width, the field is expanded to  con-
+       tain the conversion result.
+
+
+
        EXAMPLES

+       10:02', where weekday and month are pointers to strings:

        STANDARDS
+
               The  fprintf,  printf,  sprintf,  vprintf,  vfprintf,  and
+       vsprintf  functions  conform  to  ANSI C3.159-1989 (``ANSI
+       C'').
+
+
        BUGS
+
               Some floating point conversions under Linux  cause  memory
+       leaks.
+
+       The conversion formats %D, %O, and %U are not standard and
+       are provided only for backward compatibility.   These  may
+       not be provided under Linux.
+
+       The  effect of padding the %p format with zeros (either by
+       the 0 flag or by specifying a precision), and  the  benign
+       effect  (i.e.,  none)  of  the # flag on %n and %p conver-
+       sions, as well as other nonsensical combinations  such  as
+       %Ld,   are  not  standard;  such  combinations  should  be
+       avoided.
+
+       Because sprintf and vsprintf  assume  an  infinitely  long
+       string, callers must be careful not to overflow the actual
+       space; this is often impossible to assure.

        PUTS(3)             Linux Programmer's Manual             PUTS(3)
+
        
+
+
        NAME
+
               fputc,  fputs,  putc, putchar, puts - output of characters
+       and strings
+
+
        SYNOPSIS
+
               #include <stdio.h>
+
+       int fputc(int c, FILE *stream);
+       int fputs(const char *s, FILE *stream);
+       int putc(int c, FILE *stream);
+       int putchar(int c);
+       int puts(char *s);
+       int ungetc(int c, FILE *stream);
+
+
        DESCRIPTION
+
               fputc() writes the character c, cast to an unsigned  char,
+       to stream.
+
+       fputs()  writes the string s to stream, without its trail-
+       ing '\0'.
+
+       putc() is equivalent to fputc()  except  that  it  may  be
+       implemented  as  a  macro which evaluates stream more than
+       once.
+
+       putchar(c); is equivalent to putc(c,stdout).
+
+       puts() writes the string s and a trailing newline to  std-
+       out.
+
+       Calls  to  the  functions described here can be mixed with
+       each other and with calls to other output  functions  from
+       the stdio library for the same output stream.
+
+
        RETURN VALUES
+
               fputc(), putc() and putchar() return the character written
+       as an unsigned char cast to an int or EOF on error.
+
+       puts() and fputs() return a non - negative number on  suc-
+       cess, or EOF on error.
+
+
+
        CONFORMS TO
+
               ANSI - C, POSIX.1
+
+
        BUGS
+
               It  is not advisable to mix calls to output functions from
+       the stdio library with low - level calls  to  write()  for
+       the  file  descriptor  associated  with  the  same  output
+       stream; the results will be undefined  and  very  probably
+       not what you want.

        RAND(3)             Linux Programmer's Manual             RAND(3)
+
        
+
+
        NAME
+
               rand, srand - random number generator.
+
+
        SYNOPSIS
+
               #include <stdlib.h>
+
+       int rand(void);
+
+       void srand(unsigned int seed);
+
+
        DESCRIPTION
+
               The   rand()  function  returns  a  pseudo-random  integer
+       between 0 and RAND_MAX.
+
+       The srand() function sets its argument as the seed  for  a
+       new  sequence  of pseudo-random integers to be returned by
+       rand().  These sequences are repeatable by calling srand()
+       with the same seed value.
+
+       If no seed value is provided, the rand() function is auto-
+       matically seeded with a value of 1.
+
+
        RETURN VALUE
+
               The  rand()  function  returns  a  value  between  0   and
+       RAND_MAX.  The srand() returns no value.
+
+
        NOTES
+
               The  versions of rand() and srand() in the Linux C Library
+       use the same random number generator as random() and sran-
+       dom(),  so the lower-order bits should be as random as the
+       higher-order bits.  However, on older  rand()  implementa-
+       tions,  the lower-order bits are much less random than the
+       higher-order bits.
+
+       In Numerical Recipes in C: The Art of Scientific Computing
+       (William  H.  Press, Brian P. Flannery, Saul A. Teukolsky,
+       William T.  Vetterling;  New  York:  Cambridge  University
+       Press,  1990 (1st ed, p. 207)), the following comments are
+       made:
+              "If you want to generate a random integer between 1
+              and 10, you should always do it by
+
+                     j=1+(int) (10.0*rand()/(RAND_MAX+1.0));
+
+              and never by anything resembling
+
+                     j=1+((int) (1000000.0*rand()) % 10);
+
+              (which uses lower-order bits)."
+
+       Random-number  generation is a complex topic.  The Numeri-
+       cal Recipes in C book (see reference  above)  provides  an
+       excellent discussion of practical random-number generation
+       issues in Chapter 7 (Random Numbers).

        READDIR(2)          Linux Programmer's Manual          READDIR(2)
+
        
+
+
        NAME
+
               readdir - read directory entry
+
+
        SYNOPSIS
+
               #include <unistd.h>
+       #include <linux/dirent.h>
+       #include <linux/unistd.h>
+
+       _syscall3(int, readdir, uint, fd, struct dirent *, dirp, uint, count);
+
+       int readdir(unsigned int fd, struct dirent *dirp, unsigned int count);
+
+
        DESCRIPTION
+
               This  is  not the function you are interested in.  Look at
+       readdir(3) for the POSIX conforming C  library  interface.
+       This page documents the bare kernel system call interface,
+       which can change, and which is superseded by  getdents(2).
+
+       readdir  reads  one  dirent  structure  from the directory
+       pointed at by fd into the memory area pointed to by  dirp.
+       The  parameter count is ignored; at most one dirent struc-
+       ture is read.
+
+       The dirent structure is declared as follows:
+
+              struct dirent
+              {
+                  long d_ino;                 /* inode number */
+                  off_t d_off;                /* offset to this dirent */
+                  unsigned short d_reclen;    /* length of this d_name */
+                  char d_name [NAME_MAX+1];   /* file name (null-terminated) */
+              }
+
+       d_ino is an inode number.  d_off is the distance from  the
+       start  of  the  directory to this dirent.  d_reclen is the
+       size of d_name, not counting the null terminator.   d_name
+       is a null-terminated file name.
+
+
+
        RETURN VALUE
+
               On  success,  1  is  returned.   On end of directory, 0 is
+       returned.  On error, -1 is  returned,  and  errno  is  set
+       appropriately.
+
+
        ERRORS
+
               EBADF  Invalid file descriptor fd.
+
+       ENOTDIR
+              File descriptor does not refer to a directory.

        MALLOC(3)           Linux Programmer's Manual           MALLOC(3)
+
        
+
+
        NAME
+
               calloc,  malloc, free, realloc - Allocate and free dynamic
+       memory
+
+
        SYNOPSIS
+
               #include <stdlib.h>
+
+       void *calloc(size_t nmemb, size_t size);
+       void *malloc(size_t size);
+       void free(void *ptr);
+       void *realloc(void *ptr, size_t size);
+
+
        DESCRIPTION
+
               calloc() allocates memory for an array of  nmemb  elements
+       of  size bytes each and returns a pointer to the allocated
+       memory.  The memory is set to zero.
+
+       malloc() allocates size bytes and returns a pointer to the
+       allocated memory.  The memory is not cleared.
+
+       free()  frees  the  memory  space pointed to by ptr, which
+       must have been returned by a previous  call  to  malloc(),
+       calloc()  or  realloc().   If ptr is NULL, no operation is
+       performed.
+
+       realloc() changes the size of the memory block pointed  to
+       by  ptr  to size bytes.  The contents will be unchanged to
+       the minimum of the old an new sizes; newly allocated  mem-
+       ory  will  be  uninitialized.  If ptr is NULL, the call is
+       equivalent to malloc(size); if size is equal to zero,  the
+       call  is  equivalent to free(ptr).  Unless ptr is NULL, it
+       must have been returned by an earlier  call  to  malloc(),
+       calloc() or realloc().
+
+
        RETURN VALUES
+
               For calloc() and malloc(), the value returned is a pointer
+       to the allocated memory, which is suitably aligned for any
+       kind of variable, or NULL if the request fails.
+
+       free() returns no value.
+
+       realloc() returns a pointer to the newly allocated memory,
+       which is suitably aligned for any kind of variable and may
+       be  different from ptr, or NULL if the request fails or if
+       size was equal to 0.   If  realloc()  fails  the  original
+       block is left untouched - it is not freed or moved.

+
+
        NAME
+
               remove - delete a name and possibly the file it refers to
+
+
        SYNOPSIS
+
               #include <stdio.h>
+
+       int remove(const char *pathname);
+
+
        DESCRIPTION
+
               remove  deletes  a  name from the filesystem. If that name
+       was the last link to a file and no processes have the file
+       open  the  file  is  deleted and the space it was using is
+       made available for reuse.
+
+       If the name was the last link to a file but any  processes
+       still have the file open the file will remain in existence
+       until the last file descriptor referring to it is  closed.
+
+       If  the  name  referred  to  a  symbolic  link the link is
+       removed.
+
+       If the name referred to a socket, fifo or device the  name
+       for it is removed but processes which have the object open
+       may continue to use it.
+
+
        RETURN VALUE
+
               On success, zero is returned.  On error, -1  is  returned,
+       and errno is set appropriately.
+
+
        ERRORS
+
               EFAULT  pathname  points  outside  your accessible address
+               space.
+
+       EACCES  Write access to the directory containing  pathname
+               is not allowed for the process's effective uid, or
+               one of the directories in pathname did  not  allow
+               search (execute) permission.
+
+       EPERM   The  directory containing pathname has the sticky-
+               bit (S_ISVTX) set and the process's effective  uid
+               is  neither  the uid of the file to be deleted nor
+               that of the directory containing it.
+
+       ENAMETOOLONG
+               pathname was too long.
+
+       ENOENT  A directory component in pathname does  not  exist
+               or is a dangling symbolic link.
+
+       ENOTDIR A  component  used  as  a directory in pathname is
+               not, in fact, a directory.
+
+       EISDIR  pathname refers to a directory.

        RENAME(2)           Linux Programmer's Manual           RENAME(2)
+
        
+
+
        NAME
+
               rename - change the name or location of a file
+
+
        SYNOPSIS
+
               #include <unistd.h>
+
+       int rename(const char *oldpath, const char *newpath);
+
+
        DESCRIPTION
+
               rename  renames  a  file, moving it between directories if
+       required.
+
+       Any other hard links to the file (as created  using  link)
+       are unaffected.
+
+       If  newpath already exists it will be atomically overwrit-
+       ten (subject to a few conditions - see ERRORS  below),  so
+       that there is no point at which another process attempting
+       to access newpath will find it missing.
+
+       If newpath exists but the operation fails for some  reason
+       or  the  system  crashes  rename  guarantees  to  leave an
+       instance of newpath in place.
+
+       However, when overwriting there will probably be a  window
+       in  which both oldpath and newpath refer to the file being
+       renamed.
+
+       If oldpath refers to a symbolic link the link is  renamed;
+       if  newpath  refers  to  a  symbolic link the link will be
+       overwritten.
+
+
        RETURN VALUE
+
               On success, zero is returned.  On error, -1  is  returned,
+       and errno is set appropriately.
+
+
        ERRORS
+
               EISDIR  newpath  is  an existing directory, but oldpath is
+               not a directory.
+
+       EXDEV   oldpath and newpath are not on the  same  filesys-
+               tem.
+
+       ENOTEMPTY
+               newpath is a non-empty directory.
+
+       EBUSY   newpath  exists  and is the current working direc-
+               tory or root directory of some process.
+
+       EINVAL  An attempt was made to make a directory  a  subdi-
+               rectory of itself.

        BUGS
+
               Currently (Linux 0.99pl7) most of the  filesystems  except
+       Minix  will  not  allow  any overwriting renames involving
+       directories. You get EEXIST if you try.
+
+       On NFS filesystems, you can not assume that  only  because
+       the  operation  failed,  the file was not renamed.  If the
+       server does the rename operation  and  then  crashes,  the
+       retransmitted  RPC which will be processed when the server
+       is up again causes a failure.  The application is expected
+       to deal with this.  See link(2) for a similar problem.

+
+
        NAME
+
               scandir, alphasort - scan a directory for matching entries
+
+
        SYNOPSIS
+
               #include <dirent.h>
+
+       int scandir(const char *dir, struct dirent ***namelist,
+              int (*select)(const struct dirent *),
+              int (*compar)(const void *, const void *));
+
+       int alphasort(const struct dirent *a, const struct dirent *b);
+
+
        DESCRIPTION
+
               The scandir() function scans the  directory  dir,  calling
+       select()  on  each  directory  entry.   Entries  for which
+       select() returns non-zero are stored in strings  allocated
+       via  malloc(),  sorted  using  qsort() with the comparison
+       function compar(), and collected in array  namelist  which
+       is allocated via malloc().
+
+       The  alphasort()  function  can  be used as the comparison
+       function for the scandir() function to sort the  directory
+       entries  into  alphabetical order.  Its parameters are the
+       two directory entries, a and b, to compare.
+
+
        RETURN VALUE
+
               The scandir() function returns  the  number  of  directory
+       entries selected or -1 if an error occurs.
+
+       The  alphasort()  function  returns  an integer less than,
+       equal to, or greater than zero if the  first  argument  is
+       considered  to  be  respectively  less  than, equal to, or
+       greater than the second.
+

+
        NAME
+
               scanf,  fscanf,  sscanf,  vscanf, vsscanf, vfscanf - input
+       format conversion
+
+
        SYNOPSIS
+
               #include <stdio.h>
+       int scanf( const char *format, ...);
+       int fscanf( FILE *stream, const char *format, ...);
+       int sscanf( const char *str, const char *format, ...);
+
+       #include <stdarg.h>
+       int vscanf( const char *format, va_list ap);
+       int vsscanf( const char *str, const char *format, va_list ap);
+       int vfscanf( FILE *stream, const char *format, va_list ap);
+
+
        DESCRIPTION
+
               The scanf family of functions scans input according  to  a
+       format  as  described below.  This format may contain con-
+       version specifiers; the results from such conversions,  if
+       any,  are stored through the pointer arguments.  The scanf
+       function reads input from the standard input stream stdin,
+       fscanf  reads  input  from  the stream pointer stream, and
+       sscanf reads its input from the character  string  pointed
+       to by str.
+
+       The vfscanf function is analogous to vfprintf(3) and reads
+       input from the stream  pointer  stream  using  a  variable
+       argument  list  of  pointers  (see  stdarg(3).  The vscanf
+       function scans a variable argument list from the  standard
+       input  and  the  vsscanf  function scans it from a string;
+       these are analogous to the vprintf and vsprintf  functions
+       respectively.
+
+       Each  successive pointer argument must correspond properly
+       with each successive conversion specifier (but  see  `sup-
+       pression' below).  All conversions are introduced by the %
+       (percent sign) character.  The format string may also con-
+       tain other characters.  White space (such as blanks, tabs,
+       or newlines) in the format  string  match  any  amount  of

        CONVERSIONS

               Following  the  % character introducing a conversion there

+              occurs as usual, but no pointer is used; the result
+              of the conversion is simply discarded.

+              or  n  and the next pointer is a pointer to a short
+              int (rather than int).
+
+       l      Indicates either that the conversion will be one of
+              dioux  or  n and the next pointer is a pointer to a
+              long int (rather than int), or that the  conversion
+              will  be  one  of  efg  and  the  next pointer is a
+              pointer to double (rather than float).
+
+       L      Indicates that the conversion will be efg  and  the
+              next  pointer  is  a pointer to long double.  (This
+              type is not implemented; the L  flag  is  currently
+              ignored--this may not be true for Linux.)
+
+       In addition to these flags, there may be an optional maxi-
+       mum field width, expressed as a decimal  integer,  between
+       the % and the conversion.  If no width is given, a default
+       of `infinity' is used (with one exception, below);  other-
+       wise  at most this many characters are scanned in process-
+       ing the conversion.  Before conversion begins,  most  con-
+       versions skip white space; this white space is not counted
+       against the field width.
+
+       The following conversions are available:
+
+       %      Matches a literal `%'.  That is, `%%' in the format
+              string  matches  a  single input `%' character.  No
+              conversion is done, and assignment does not  occur.
+
+       d      Matches  an  optionally signed decimal integer; the
+              next pointer must be a pointer to int.
+
+       D      Equivalent to ld; this exists  only  for  backwards
+              compatibility.
+
+       i      Matches  an  optionally  signed  integer;  the next
+              pointer must be a pointer to int.  The  integer  is
+              read  in base 16 if it begins with `0x' or `0X', in
+              base 8 if it begins with `0', and in base 10 other-
+              wise.   Only characters that correspond to the base
+              are used.
+
+       o      Matches an octal integer; the next pointer must  be
+              a pointer to unsigned int.
+
+       O      Equivalent to lo; this exists for backwards compat-
+              ibility.
+
+       u      Matches an optionally signed decimal  integer;  the
+              next pointer must be a pointer to unsigned int.
+
+       x      Matches an optionally a signed hexadecimal integer;
+              the next pointer must be a pointer to unsigned int.

+              usual skip of leading white  space  is  suppressed.
+              To skip white space first, use an explicit space in

+              except  close  bracket,  zero  through  nine,   and
+              hyphen'.   The string ends with the appearance of a
+              character not in the (or, with  a  circumflex,  in)
+              set or when the field width runs out.
+
+       p      Matches  a  pointer  value  (as  printed by `%p' in
+              printf(3); the next pointer must be  a  pointer  to
+              void.
+
+       n      Nothing is expected; instead, the number of charac-
+              ters consumed thus far from  the  input  is  stored
+              through  the  next pointer, which must be a pointer
+              to int.  This is not a conversion, although it  can
+              be suppressed with the * flag.
+
+       For  backwards  compatibility, other conversion characters
+       (except `\0') are taken as if they were `%d' or, if upper-
+       case, `%ld', and a `conversion' of `%\0' causes an immedi-
+       ate return of EOF.   The  F  and  X  conversions  will  be
+       changed in the future to conform to the
+        ANSI  C  standard,  after  which  they  will act like and
+       respectively.  The behavior of Linux on  the  non-standard
+       points is not known by this documenter.
+
+
+
        RETURN VALUES
+
               These functions return the number of input items assigned,
+       which can be fewer than provided for, or even zero, in the
+       event  of  a matching failure.  Zero indicates that, while
+       there was input available, no conversions  were  assigned;
+       typically  this is due to an invalid input character, such
+       as an alphabetic character for  a  `%d'  conversion.   The
+       value  EOF  is  returned if an input failure occurs before
+       any conversion such as an end-of-file occurs. If an  error
+       or end-of-file occurs after conversion has begun, the num-
+       ber of conversions which were  successfully  completed  is
+       returned.

+
+
        NAME
+
               setbuf,  setbuffer, setlinebuf, setvbuf - stream buffering
+       operations
+
+
        SYNOPSIS
+
               #include <stdio.h>
+
+       int setbuf( FILE *stream, char *buf);
+       int setbuffer( FILE *stream, char *buf, size_tsize);
+       int setlinebuf( FILE *stream);
+       int setvbuf( FILE *stream, char *buf, int mode , size_t
+       size);
+
+
        DESCRIPTION
+
               The  three  types  of  buffering available are unbuffered,
+       block buffered, and line buffered.  When an output  stream
+       is unbuffered, information appears on the destination file
+       or terminal as soon as written; when it is block  buffered
+       many  characters are saved up and written as a block; when
+       it is line buffered characters are saved up until  a  new-
+       line  is  output or input is read from any stream attached
+       to a terminal  device  (typically  stdin).   The  function
+       fflush(3)  may be used to force the block out early.  (See
+       fclose(3).)  Normally all files are block buffered.   When
+       the  first  I/O  operation  occurs on a file, malloc(3) is
+       called, and a buffer is obtained.  If a stream refers to a
+       terminal  (as  stdout  normally does) it is line buffered.
+       The standard error stream stderr is always unbuffered.
+
+       The setvbuf function may be used at any time on  any  open
+       stream  to  change its buffer.  The mode parameter must be
+       one of the following three macros:
+
+              _IONBF unbuffered
+
+              _IOLBF line buffered
+
+              _IOFBF fully buffered
+
+       Except for unbuffered files, the buf argument should point
+       to  a buffer at least size bytes long; this buffer will be
+       used instead of the current buffer.  If the  argument  buf
+       is  NULL,  only the mode is affected; a new buffer will be
+       allocated on  the  next  read  or  write  operation.   The
+       setvbuf  function  may  be  used at any time, but can only
+       change the mode of a stream when  it  is  not  ``active'':
+       that  is,  before  any I/O, or immediately after a call to
+       fflush.
+
+       The other three calls are, in effect, simply  aliases  for
+       calls  to setvbuf.  The setbuf function is exactly equiva-
+       lent to the call
+
+              setvbuf(stream,  buf,  buf    _IOFBF   :   _IONBF,
+

+              BUFSIZ);
+
+       The  setbuffer  function is the same, except that the size
+       of the buffer is up  to  the  caller,  rather  than  being
+       determined by the default BUFSIZ.  The setlinebuf function
+       is exactly equivalent to the call:
+
+              setvbuf(stream, (char *)NULL, _IOLBF, 0);

        STANDARDS
+
               The   setbuf   and   setvbuf  functions  conform  to  ANSI
+       C3.159-1989 (``ANSI C'').
+
+
        BUGS
+
               The setbuffer and setlinebuf functions are not portable to
+       versions  of  BSD  before 4.2BSD, and may not be available
+       under Linux.  On 4.2BSD and 4.3BSD systems, setbuf  always
+       uses a suboptimal buffer size and should be avoided.
+
+       You  must  make sure that both buf and the space it points
+       to still exist by the time stream is  closed,  which  also
+       happens at program termination.
+
+       For example, the following is illegal:
+
+       #include <stdio.h>
+       int main()
+       {
+           char buf[BUFSIZ];
+           setbuf(stdin, buf);
+           printf("Hello, world!\n");
+           return 0;

        SETREGID(2)         Linux Programmer's Manual         SETREGID(2)
+
        
+
+
        NAME
+
               setregid, setegid - set real and / or effective group ID
+
+
        SYNOPSIS
+
               #include <unistd.h>
+
+       int setregid(gid_t rgid, gid_t egid);
+       int setegid(gid_t egid);
+
+
        DESCRIPTION
+
               setregid sets real and effective group ID's of the current
+       process.  Un-privileged users may change the real group ID
+       to the effective group ID and vice-versa.
+
+       Prior  to  Linux  1.1.38, the saved ID paradigm, when used
+       with setregid or setegid was broken.  Starting at  1.1.38,
+       it is also possible to set the effective group ID from the
+       saved user ID.
+
+       Only the super-user may make other changes.
+
+       Supplying a value of -1 for either the real  or  effective
+       group ID forces the system to leave that ID unchanged.
+
+       Currently   (libc-4.x.x),  setegid(egid)  is  functionally
+       equivalent to setregid(-1, egid).
+
+       If the real group ID is changed or the effective group  ID
+       is set to a value not equal to the previous real group ID,
+       the saved group ID will be set to the new effective  group
+       ID.
+
+
        RETURN VALUE
+
               On  success,  zero is returned.  On error, -1 is returned,
+       and errno is set appropriately.
+
+
        ERRORS
+
               EPERM   The current process  is  not  the  super-user  and
+               changes  other  than  (i)  swapping  the effective
+               group ID with the real group ID  or  (ii)  setting
+               one to the value of the other or (iii) setting the
+               effective group ID to the value of the saved group
+               ID was specified.
+

               The setregid function call appeared in BSD 4.2.

+
+
        NAME
+
               setenv - change or add an environment variable
+
+
        SYNOPSIS
+
               #include <stdlib.h>
+
+       int setenv(const char *name, const char *value, int overwrite);
+
+       void unsetenv(const char *name);
+
+
        DESCRIPTION
+
               The  setenv() function adds the variable name to the envi-
+       ronment with the value value, if  name  does  not  already
+       exist.   If  name  does exist in the environment, then its
+       value is changed to value if  overwrite  is  non-zero;  if
+       overwrite  is zero, then the value of name is not changed.
+
+       The unsetenv() function deletes the variable name from the
+       environment.
+
+
        RETURN VALUE
+
               The  setenv()  function  returns zero on success, or -1 if
+       there was insufficient space in the environment.

+
+
        NAME
+
               setgid - set group identity
+
+
        SYNOPSIS
+
               #include <unistd.h>
+
+       int setgid(gid_t gid)
+
+
        DESCRIPTION
+
               setgid sets the effective group ID of the current process.
+       If the caller is the superuser, the real and  saved  group
+       ID's are also set.
+
+       Under   Linux,   setgid  is  implemented  like  SYSV  with
+       SAVED_IDS.  This allows a setgid (other than root) program
+       to  drop  all  of it's group privileges, do some un-privi-
+       leged work, and  then  re-engage  the  original  effective
+       group ID in a secure manner.
+
+       If the user is root or the program is setgid root, special
+       care must be taken. The setgid function checks the  effec-
+       tive  gid  of  the  caller and if it is the superuser, all
+       process related group ID's are set to gid.  After this has
+       occurred,  it is impossible for the program to regain root
+       privileges.
+
+
        RETURN VALUE
+
               On success, zero is returned.  On error, -1  is  returned,
+       and errno is set appropriately.
+
+
        ERRORS
+
               EPERM   The  user  is not the super-user, and gid does not
+               match the effective or saved group ID of the call-
+               ing process.

        NAME
+
               setjmp - save stack context for non-local goto
+
+
        SYNOPSIS
+
               #include <setjmp.h>
+
+       int setjmp(jmp_buf env );
+
+
        DESCRIPTION
+
               setjmp  and  longjmp(3) are useful for dealing with errors
+       and interrupts encountered in a low-level subroutine of  a
+       program.   setjmp() saves the stack context/environment in
+       env for later use by longjmp().  The stack context will be
+       invalidated if the function which called setjmp() returns.
+
+
        RETURN VALUE
+
               It returns the value 0 if returning directly and  non-zero
+       when returning from longjmp() using the saved context.
+
+
        CONFORMING TO
+
               POSIX
+
+
        NOTES
+
               POSIX does not specify if the signal context will be saved
+       or  not.   If  you  want  to  save   signal   masks,   use
+       sigsetjmp(3).   setjmp() makes programs hard to understand
+       and maintain.  If possible an alternative should be  used.

        NAME
+
               setlocale - set the current locale.
+
+
        SYNOPSIS
+
               #include <locale.h>
+
+       char *setlocale(int category, const char * locale);
+
+
        DESCRIPTION
+
               The  setlocale() function is used to set or query the pro-
+       gram's current locale.  If locale is "C" or  "POSIX",  the
+       current locale is set to the portable locale.
+
+       If  locale  is "", the locale is set to the default locale
+       which is selected from the environment variable LANG.
+
+       On startup of the main program, the portable "C" locale is
+       selected as default.
+
+       The  argument  category  determines  which  functions  are
+       influenced by the new locale:
+
+       LC_ALL for all of the locale.
+
+       LC_COLLATE
+              for the functions strcoll() and strxfrm().
+
+       LC_CTYPE
+              for the  character  classification  and  conversion
+              routines.
+
+       LC_MONETARY
+              for localeconv().
+
+       LC_NUMERIC
+              for the decimal character.
+
+       LC_TIME
+              for  strftime().  NULL if the request cannot not be
+              honored.  This string may be  allocated  in  static
+              storage.
+
+       A  program  may be made portable to all locales by calling
+       setlocale(LC_ALL, "" ) after program   initialization,  by
+       using  the  values  returned  from a localeconv() call for
+       locale - dependent information and by using  strcoll()  or
+       strxfrm() to compare strings.
+
+
        CONFORMS TO
+
               ANSI C, POSIX.1
+
+       Linux  supports  the  portable locales "C" and "POSIX" and
+       also the  European  Latin-1  "ISO-8859-1"  ,  and  Russian
+       "KOI-8" locales.

        SETPGID(2)          Linux Programmer's Manual          SETPGID(2)
+
        
+
+
        NAME
+
               setpgid, getpgid, setpgrp, getpgrp - set/get process group
+
+
        SYNOPSIS
+
               #include <unistd.h>
+
+       int setpgid(pid_t pid, pid_t pgid);
+       pid_t getpgid(pid_t pid);
+       int setpgrp(void);
+       pid_t getpgrp(void);
+
+
        DESCRIPTION
+
               setpgid sets the process group ID of the process specified
+       by  pid  to  pgid.   If pid is zero, the process ID of the
+       current process is used.  If pgid is zero, the process  ID
+       of the process specified by pid is used.
+
+       getpgid returns the process group ID of the process speci-
+       fied by pid.  If pid is zero, the process ID of  the  cur-
+       rent process is used.
+
+       In  the  Linux  DLL  4.4.1  library,  setpgrp simply calls
+       setpgid(0,0).
+
+       getpgrp is equivalent to getpgid(0).
+
+       Process groups are used for distribution of  signals,  and
+       by  terminals  to arbitrate requests for their input: pro-
+       cesses that have the same process group  as  the  terminal
+       are  foreground and may read, while others will block with
+       a signal if they attempt to read.
+
+       These calls are thus used by programs such  as  csh(1)  to
+       create  process  groups  in implementing job control.  The
+       TIOCGPGRP and TIOCSPGRP calls described in termios(4)  are
+       used to get/set the process group of the control terminal.
+
+
        RETURN VALUE
+
               On success, setpgid and setpgrp return zero.  On error, -1
+       is returned, and errno is set appropriately.
+
+       getpgid  returns a process group on success.  On error, -1
+       is returned, and errno is set appropriately.
+
+       getpgrp always returns the current process group.
+
+
        ERRORS
+
               EINVAL  pgid is less than 0.
+
+       EPERM   Various permission violations.
+
+       ESRCH   pid does not match any process.

        SYNOPSIS
+
               #include <unistd.h>
+
+       pid_t setsid(void);
+
+
        DESCRIPTION
+
               setsid()  creates  a new session if the calling process is
+       not a process group leader.  The calling  process  is  the
+       leader of the new session, the process group leader if the
+       new process group, and has no controlling tty.   The  pro-
+       cess  group ID of the calling process is set to the PID of
+       the calling process.  The calling process will be the only
+       process in this new process group and in this new session.
+
+
        RETURN VALUE
+
               The process group ID of the calling process.
+
+
        ERRORS
+
               On error, -1 will be returned.  The only error  which  can
+       happen is EPERM.

+
        
+
+
        NAME
+
               setuid - set user identity
+
+
        SYNOPSIS
+
               #include <unistd.h>
+
+       int setuid(uid_t uid)
+
+
        DESCRIPTION
+
               setuid  sets the effective user ID of the current process.
+       If the caller is the superuser, the real  and  saved  user
+       ID's are also set.
+
+       Under   Linux,   setuid  is  implemented  like  SYSV  with
+       SAVED_IDS.  This allows a setuid (other than root) program
+       to drop all of it's user privileges, do some un-privileged
+       work, and then re-engage the original effective user ID in
+       a secure manner.
+
+       If the user is root or the program is setuid root, special
+       care must be taken. The setuid function checks the  effec-
+       tive  uid  of  the  caller and if it is the superuser, all
+       process related user ID's are set to uid.  After this  has
+       occurred,  it is impossible for the program to regain root
+       privileges.
+
+
        RETURN VALUE
+
               On success, zero is returned.  On error, -1  is  returned,
+       and errno is set appropriately.
+
+
        ERRORS
+
               EPERM   The  user  is not the super-user, and uid does not
+               match the effective or saved user ID of the  call-
+               ing process.

+
+
        NAME
+
               signal - ANSI C signal handling.
+
+
+
        SYNOPSIS
+
               #include <signal.h>
+
+
+       void (*signal(int signum, void (*handler)(int)))(int);
+
+
+
        DESCRIPTION
+
               The  signal  system call installs a new signal handler for
+       signal signum.  The signal handler is set to handler which
+       may be a user specified function, or one of the following:
+
+              SIG_IGN
+                     Ignore the signal.
+
+              SIG_DFL
+                     Reset the signal to its default behavior.
+
+
+
+
        RETURN VALUE
+
               signal returns the previous value of the  signal  handler,
+       or SIG_ERR on error.
+
+
+
        NOTES
+
               Signal handlers cannot be set for SIGKILL or SIGSTOP.
+
+       Unlike BSD systems, signals under Linux are reset to their
+       default behavior when raised.
+
+       If you're confused by the prototype at  the  top  of  this
+       manpage, it may help to see it separated out thus:
+
+       typedef void (*sighandler_t)(int);
+       sighandler_t signal(int signum, sighandler_t handler);

+
        
+
+
        NAME
+
               sleep - Sleep for the specified number of seconds
+
+
        SYNOPSIS
+
               #include <unistd.h>
+
+       unsigned int sleep(unsigned int seconds);
+
+
        DESCRIPTION
+
               sleep() makes the current process sleep until seconds sec-
+       onds have  elapsed  or  a  signal  arrives  which  is  not
+       ignored.
+
+
        RETURN VALUE
+
               Zero  if  the requested time has elapsed, or the number of
+       seconds left to sleep.
+
+
        CONFORMS TO
+
               POSIX.1
+
+
        BUGS
+
               sleep() may be implemented using SIGALRM; mixing calls  to
+       alarm() and sleep() is a bad idea.
+
+       Using  longjmp()  from  a  signal handler or modifying the
+       handling of SIGALRM while sleeping  will  cause  undefined
+       results.

        NAME
+
               printf,  fprintf,  sprintf,  vprintf, vfprintf, vsprintf -
+       formatted output conversion
+
+
        SYNOPSIS
+
               #include <stdio.h>
+
+       int printf( const char *format, ...);
+       int fprintf( FILE *stream, const char *format, ...);
+       int sprintf( char *str, const char *format, ...);
+
+       #include <stdarg.h>
+
+       int vprintf( const char *format, va_list ap);
+       int vfprintf( FILE *stream, const  char  *format,  va_list
+       ap);
+       int vsprintf( char *str, char *format, va_list ap);
+
+
        DESCRIPTION
+
               The  printf  family of functions produces output according
+       to a format as described below.  Printf and vprintf  write
+       output  to stdout, the standard output stream; fprintf and
+       vfprintf write output to the given output stream; sprintf,
+       and  vsprintf  write  to  the character string str.  These
+       functions write the output under the control of  a  format
+       string  that  specifies how subsequent arguments (or argu-
+       ments accessed via the variable-length argument facilities
+       of  stdarg(3)  are  converted for output.  These functions
+       return the number of characters printed (not including the
+       trailing `\0' used to end output to strings).
+
+       The  format string is composed of zero or more directives:
+       ordinary characters (not %), which are copied unchanged to
+       the  output stream; and conversion specifications, each of
+       which results in fetching zero or  more  subsequent  argu-
+       ments.  Each conversion specification is introduced by the
+       character  %.   The  arguments  must  correspond  properly
+       (after  type  promotion)  with  the  conversion specifier.
+       After the %, the following appear in sequence:
+
+       o      Zero or more of the following flags:
+
+              #      specifying that the  value  should  be  con-
+                     verted  to an ``alternate form''.  For c, d,
+                     i, n, p, s, and u conversions,  this  option
+                     has  no effect.  For o conversions, the pre-
+                     cision of the number is increased  to  force
+                     the  first character of the output string to
+                     a zero (except if a zero  value  is  printed
+                     with  an explicit precision of zero).  For x
+                     and X conversions, a non-zero result has the
+                     string  `0x'  (or  `0X'  for  X conversions)
+                     prepended to it.  For e, E, f, g, and G con-
+                     versions,  the  result will always contain a

+                     decimal point, even if no digits  follow  it
+                     (normally,  a  decimal  point appears in the
+                     results of those conversions only if a digit
+                     follows).  For g and G conversions, trailing
+                     zeros are not removed  from  the  result  as
+                     they would otherwise be.
+
+              0      specifying  zero  padding.   For all conver-
+                     sions  except  n,  the  converted  value  is
+                     padded  on  the  left with zeros rather than
+                     blanks.  If a  precision  is  given  with  a
+                     numeric  conversion  (d,  i, o, u, i, x, and
+                     X), the 0 flag is ignored.
+
+              -      (a negative field width flag) indicates  the
+                     converted  value  is  to be left adjusted on
+                     the field boundary.  Except  for  n  conver-
+                     sions,  the converted value is padded on the
+                     right with blanks, rather than on  the  left
+                     with  blanks or zeros.  A - overrides a 0 if
+                     both are given.
+
+                     (a space) specifying that a blank should  be
+                     left  before a positive number produced by a
+                     signed conversion (d, e, E, f, g, G, or  i).
+
+              +      specifying  that  a  sign  always  be placed
+                     before a number produced by a signed conver-
+                     sion.   A  +  overrides  a space if both are
+                     used.
+
+       o      An optional decimal digit string specifying a mini-
+              mum  field width.  If the converted value has fewer
+              characters than the field width, it will be  padded
+              with  spaces  on  the  left (or right, if the left-
+              adjustment flag has been given)  to  fill  out  the
+              field width.
+
+       o      An  optional  precision,  in  the  form of a period
+              (`.')  followed by an optional  digit  string.   If
+              the digit string is omitted, the precision is taken
+              as zero.  This gives the minimum number  of  digits
+              to appear for d, i, o, u, x, and X conversions, the
+              number of digits to appear after the  decimal-point
+              for  e, E, and f conversions, the maximum number of
+              significant digits for g and G conversions, or  the
+              maximum  number  of characters to be printed from a
+              string for s conversions.
+
+       o      The optional character h, specifying that a follow-
+              ing d, i, o, u, x, or X conversion corresponds to a
+              short int or unsigned short int argument, or that a
+              following  n conversion corresponds to a pointer to
+              a short int argument.

+
+       o      The optional character l (ell)  specifying  that  a
+              following d, i, o, u, x, or X conversion applies to
+              a pointer to a long int or unsigned long int  argu-
+              ment,  or that a following n conversion corresponds
+              to a pointer to a long int argument.
+
+       o      The character L specifying that a following  e,  E,
+              f,  g, or G conversion corresponds to a long double
+              argument.
+
+       o      A character that specifies the type  of  conversion
+              to be applied.
+
+       A  field  width or precision, or both, may be indicated by
+       an asterisk `*' instead of a digit string.  In this  case,
+       an  int argument supplies the field width or precision.  A
+       negative field width is treated as a left adjustment  flag
+       followed  by  a positive field width; a negative precision
+       is treated as though it were missing.
+
+       The conversion specifiers and their meanings are:
+
+       diouxX The int (or appropriate variant) argument  is  con-
+              verted  to signed decimal (d and i), unsigned octal
+              (o, unsigned decimal (u, or unsigned hexadecimal (x
+              and X) notation.  The letters abcdef are used for x
+              conversions; the letters ABCDEF are used for X con-
+              versions.  The precision, if any, gives the minimum
+              number of digits that must appear; if the converted
+              value  requires  fewer  digits, it is padded on the
+              left with zeros.
+
+       DOU    The long int argument is converted to signed  deci-
+              mal, unsigned octal, or unsigned decimal, as if the
+              format had been ld, lo, or lu respectively.   These
+              conversion  characters  are  deprecated,  and  will
+              eventually disappear.
+
+       eE     The double argument is rounded and converted in the
+              style  [-]d.dddedd  where there is one digit before
+              the decimal-point character and the number of  dig-
+              its after it is equal to the precision; if the pre-
+              cision is missing, it is taken as 6; if the  preci-
+              sion  is  zero, no decimal-point character appears.
+              An E conversion uses the letter E (rather  than  e)
+              to  introduce  the  exponent.   The exponent always
+              contains at least two digits; if the value is zero,
+              the exponent is 00.
+
+       f      The  double  argument  is  rounded and converted to
+              decimal notation in the style [-]ddd.ddd, where the
+              number  of digits after the decimal-point character
+              is equal to the precision  specification.   If  the
+              precision  is  missing,  it  is  taken as 6; if the
+

+
+              precision  is  explicitly  zero,  no  decimal-point
+              character  appears.  If a decimal point appears, at
+              least one digit appears before it.
+
+       g      The double argument is converted in style  f  or  e
+              (or  E for G conversions).  The precision specifies
+              the number of significant digits.  If the precision
+              is missing, 6 digits are given; if the precision is
+              zero, it is treated as 1.  Style e is used  if  the
+              exponent  from  its  conversion  is less than -4 or
+              greater than or equal to the  precision.   Trailing
+              zeros  are  removed from the fractional part of the
+              result; a decimal point appears only if it is  fol-
+              lowed by at least one digit.
+
+       c      The  int argument is converted to an unsigned char,
+              and the resulting character is written.
+
+       s      The ``char *'' argument is expected to be a pointer
+              to  an  array  of  character  type  (pointer  to  a
+              string).  Characters from the array are written  up
+              to (but not including) a terminating NUL character;
+              if a precision is specified, no more than the  num-
+              ber  specified  are  written.   If  a  precision is
+              given, no null character need be  present;  if  the
+              precision  is not specified, or is greater than the
+              size of the array, the array must contain a  termi-
+              nating NUL character.
+
+       p      The  ``void *'' pointer argument is printed in hex-
+              adecimal (as if by %#x or %#lx).
+
+       n      The number of characters written so far  is  stored
+              into  the  integer  indicated  by the ``int *'' (or
+              variant) pointer argument.   No  argument  is  con-
+              verted.
+
+       %      A  `%'  is  written.  No argument is converted. The
+              complete conversion specification is `%%'.
+
+       In no case does a non-existent or small field width  cause
+       truncation  of  a  field; if the result of a conversion is
+       wider than the field width, the field is expanded to  con-
+       tain the conversion result.
+
+
+
        EXAMPLES

               To  print  a  date  and  time in the form `Sunday, July 3,
+       10:02', where weekday and month are pointers to strings:

        STANDARDS
+
               The  fprintf,  printf,  sprintf,  vprintf,  vfprintf,  and
+       vsprintf  functions  conform  to  ANSI C3.159-1989 (``ANSI
+       C'').
+
+
        BUGS
+
               Some floating point conversions under Linux  cause  memory
+       leaks.
+
+       The conversion formats %D, %O, and %U are not standard and
+       are provided only for backward compatibility.   These  may
+       not be provided under Linux.
+
+       The  effect of padding the %p format with zeros (either by
+       the 0 flag or by specifying a precision), and  the  benign
+       effect  (i.e.,  none)  of  the # flag on %n and %p conver-
+       sions, as well as other nonsensical combinations  such  as
+       %Ld,   are  not  standard;  such  combinations  should  be
+       avoided.
+
+       Because sprintf and vsprintf  assume  an  infinitely  long
+       string, callers must be careful not to overflow the actual
+       space; this is often impossible to assure.

        NAME
+
               stat, fstat, lstat - get file status
+
+
        SYNOPSIS
+
               #include <sys/stat.h>
+       #include <unistd.h>
+
+       int stat(const char *file_name, struct stat *buf);
+       int fstat(int filedes, struct stat *buf);
+       int lstat(const char *file_name, struct stat *buf);
+
+
        DESCRIPTION
+
               These  functions  return  information  about the specified
+       file.  You do not need any access rights to  the  file  to
+       get  this  information  but  you need search rights to all
+       directories named in the path leading to the file.
+
+       stat stats the file pointed to by file_name and  fills  in
+       buf.
+
+       lstat  is  identical  to  stat,  only  the  link itself is
+       stated, not the file  that  is  obtained  by  tracing  the
+       links.
+
+       fstat  is identical to stat, only the open file pointed to
+       by filedes (as returned by fopen(3) ) is stated  in  place
+       of file_name.
+
+
+       They  all  return  a  stat structure, which is declared as
+       follows:
+
+              struct stat
+              {
+                  dev_t         st_dev;      /* device */
+                  ino_t         st_ino;      /* inode */
+                  umode_t       st_mode;     /* protection */
+                  nlink_t       st_nlink;    /* number of hard links */
+                  uid_t         st_uid;      /* user ID of owner */
+                  gid_t         st_gid;      /* group ID of owner */
+                  dev_t         st_rdev;     /* device type (if inode device) */
+                  off_t         st_size;     /* total size, in bytes */
+                  unsigned long st_blksize;  /* blocksize for filesystem I/O */
+                  unsigned long st_blocks;   /* number of blocks allocated */
+                  time_t        st_atime;    /* time of last access */
+                  time_t        st_mtime;    /* time of last modification */
+                  time_t        st_ctime;    /* time of last change */
+              };
+
+       Note that st_blocks may not always be in terms  of  blocks
+       of  size  st_blksize, and that st_blksize may instead pro-
+       vide a notion of the "preferred" blocksize  for  efficient
+       file system I/O.

+
        
+
+       Not all of the Linux filesystems implement all of the time
+       fields.  Traditionally, st_atime is changed  by  mknod(2),
+       utime(2), read(2), write(2), and truncate(2).
+
+       Traditionally,  st_mtime is changed by mknod(2), utime(2),
+       and write(2).  The st_mtime is not changed for changes  in
+       owner, group, hard link count, or mode.
+
+       Traditionally,  st_ctime  is changed by writing or by set-
+       ting inode information (i.e., owner,  group,  link  count,
+       mode, etc.).
+
+       The following macros are defined to check the file type:
+
+              S_ISLNK(m)  is it a symbolic link
+
+              S_ISREG(m)  regular file
+
+              S_ISDIR(m)  directory
+
+              S_ISCHR(m)  character device
+
+              S_ISBLK(m)  block device
+
+              S_ISFIFO(m) fifo
+
+              S_ISSOCK(m) socket
+
+       The following flags are defined for the st_mode field:
+
+              S_IFMT   00170000  bitmask  for  the file type bit-
+                       fields
+
+              S_IFSOCK 0140000 socket
+
+              S_IFLNK  0120000 symbolic link
+
+              S_IFREG  0100000 regular file
+
+              S_IFBLK  0060000 block device
+
+              S_IFDIR  0040000 directory
+
+              S_IFCHR  0020000 character device
+
+              S_IFIFO  0010000 fifo
+
+              S_ISUID  0004000 set UID bit
+
+              S_ISGID  0002000 set GID bit
+
+              S_ISVTX  0001000 sticky bit
+
+              S_IRWXU  00700 user (file owner)  has  read,  write

        NAME
+
               strcasecmp,  strncasecmp  -  compare  two strings ignoring
+       case
+
+
        SYNOPSIS
+
               #include <string.h>
+
+       int strcasecmp(const char *s1, const char *s2);
+
+       int strncasecmp(const char *s1, const char *s2, size_t n);
+
+
        DESCRIPTION
+
               The strcasecmp() function compares the two strings s1  and
+       s2,  ignoring  the  case of the characters.  It returns an
+       integer less than, equal to, or greater than zero if s1 is
+       found,  respectively,  to  be  less  than, to match, or be
+       greater than s2.
+
+       The strncasecmp() function is similar, except it only com-
+       pares the first n characters of s1.
+
+
        RETURN VALUE
+
               The  strcasecmp()  and  strncasecmp()  functions return an
+       integer less than, equal to, or greater than  zero  if  s1
+       (or  the first n bytes thereof) is found, respectively, to
+       be less than, to match, or be greater than s2.

        NAME
+
               strcat, strncat - concatenate two strings
+
+
        SYNOPSIS
+
               #include <string.h>
+
+       char *strcat(char *dest, const char *src);
+
+       char *strncat(char *dest, const char *src, size_t n);
+
+
        DESCRIPTION
+
               The  strcat()  function appends the src string to the dest
+       string overwriting the `\0' character at the end of  dest,
+       and  then  adds a terminating `\0' character.  The strings
+       may not overlap, and the  dest  string  must  have  enough
+       space for the result.
+
+       The  strncat()  function  is similar, except that only the
+       first n characters of src are appended to dest.
+
+
        RETURN VALUE
+
               The strcat() and strncat() functions return a  pointer  to
+       the resulting string dest.

        NAME
+
               strcoll - compare two strings using the current locale
+
+
        SYNOPSIS
+
               #include <string.h>
+
+       int strcoll(const char *s1, const char *s2);
+
+
        DESCRIPTION
+
               The strcoll() function compares the two strings s1 and s2.
+       It returns an integer less than, equal to, or greater than
+       zero  if  s1  is  found, respectively, to be less than, to
+       match, or be greater than s2.  The comparison is based  on
+       strings  interpreted as appropriate for the program's cur-
+       rent locale for category LC_COLLATE.  (See  setlocale(3)).
+
+
        RETURN VALUE
+
               The strcoll() function returns an integer less than, equal
+       to, or greater than zero if s1 is found, respectively,  to
+       be  less  than, to match, or be greater than s2, when both
+       are interpreted as appropriate for the current locale.

        NOTES
+
               The Linux C Library currently hasn't implemented the  com-
+       plete POSIX-collating.
+
+       In  the  "POSIX" or "C" locales strcoll() is equivalent to
+       strcmp().

        NAME
+
               strftime - format date and time
+
+
        SYNOPSIS
+
               #include <time.h>
+
+       size_t strftime(char *s, size_t max, const char *format,
+                           const struct tm *tm);
+
+
        DESCRIPTION
+
               The  strftime()  function  formats the broken-down time tm
+       according to the format specification  format  and  places
+       the result in the character array s of size max.
+
+       Ordinary characters placed in the format string are copied
+       to s without conversion.  Conversion specifiers are intro-
+       duced  by  a  `%' character, and are replaced in s as fol-
+       lows:
+
+       %a     The abbreviated weekday name according to the  cur-
+              rent locale.
+
+       %A     The  full  weekday  name  according  to the current
+              locale.
+
+       %b     The abbreviated month name according to the current
+              locale.
+
+       %B     The  full  month  name  according  to  the  current
+              locale.
+
+       %c     The preferred date and time representation for  the
+              current locale.
+
+       %d     The  day  of the month as a decimal number (range 0
+              to 31).
+
+       %H     The hour as a decimal number using a 24-hour  clock
+              (range 00 to 23).
+
+       %I     The  hour as a decimal number using a 12-hour clock
+              (range 01 to 12).
+
+       %j     The day of the year as a decimal number (range  001
+              to 366).
+
+       %m     The month as a decimal number (range 10 to 12).
+
+       %M     The minute as a decimal number.
+
+       %p     Either  `am'  or  `pm'  according to the given time
+              value, or the corresponding strings for the current
+              locale.

+              };
+
+       The members of the tm structure are:
+
+       tm_sec The number of seconds after the minute, normally in
+              the range 0 to 59, but can be up to 61 to allow for
+              leap seconds.

        STRTOD(3)           Linux Programmer's Manual           STRTOD(3)
+
        
+
+
        NAME
+
               strtod - convert ASCII string to double
+
+
        SYNOPSIS
+
               #include <stdlib.h>
+
+       double strtod(const char *nptr, char **endptr
+
+
        DESCRIPTION
+
               The  strtod  function  converts the initial portion of the
+       string pointed to by nptr to double representation.
+
+       The expected form  of  the  string  is  an  optional  plus
+       (``+'')  or  minus  sign (``-'') followed by a sequence of
+       digits optionally containing  a  decimal-point  character,
+       optionally  followed by an exponent.  An exponent consists
+       of an ``E'' or ``e'', followed  by  an  optional  plus  or
+       minus sign, followed by a sequence of digits.
+
+       Leading  white-space  characters in the string (as defined
+       by the isspace(3) function) are skipped.
+
+
        RETURN VALUES
+
               The strtod function returns the converted value, if any.
+
+       If endptr is not NULL, a pointer to  the  character  after
+       the last character used in the conversion is stored in the
+       location referenced by endptr.
+
+       If no conversion is performed, zero is  returned  and  the
+       value  of  nptr  is  stored  in the location referenced by
+       endptr.
+
+       If the correct value would cause overflow, plus  or  minus
+       HUGE_VAL is returned (according to the sign of the value),
+       and ERANGE is stored in errno.  If the correct value would
+       cause  underflow, zero is returned and ERANGE is stored in
+       errno.
+
+
        ERRORS
+
               ERANGE Overflow or underflow occurred.

        NAME
+
               sysconf - Get configuration information at runtime
+
+
        SYNOPSIS
+
               #include <unistd.h>
+
+       long sysconf(int name);
+
+
        DESCRIPTION
+
               sysconf()  provides a way for the application to determine
+       values for system limits or options at runtime.
+
+       The equivalent macros defined in <unistd.h> can only  give
+       conservative  values;  if  an  application  wants  to take
+       advantage of values which may change, a call to  sysconf()
+       can be made, which may yield more liberal results.
+
+       For  getting  information  about  a  particular  file, see
+       fpathconf() or pathconf().
+
+       The following values are supported for name.   First,  the
+       POSIX.1 compatible values:
+
+       _SC_ARG_MAX
+              The  maximum  length of the arguments to the exec()
+              family of functions;  the  corresponding  macro  is
+              ARG_MAX.
+
+       _SC_CHILD_MAX
+              The  number  of simultaneous processes per user id,
+              the corresponding macro is _POSIX_CHILD_MAX.
+
+       _SC_CLK_TCK
+              The number of clock ticks per  second;  the  corre-
+              sponding macro is CLK_TCK.
+
+       _SC_STREAM_MAX
+              The  maximum  number  of streams that a process can
+              have open at any  time.   The  corresponding  POSIX
+              macro  is  STREAM_MAX, the corresponding standard C
+              macro is FOPEN_MAX.
+
+       _SC_TZNAME_MAX
+              The maximum number of bytes in a timezone name, the
+              corresponding macro is TZNAME_MAX.
+
+       _SC_OPEN_MAX
+              The maximum number of files that a process can have
+              open  at  any  time,  the  corresponding  macro  is
+              _POSIX_OPEN_MAX.
+
+       _SC_JOB_CONTROL
+              This indicates whether POSIX - style job control is
+              supported,    the    corresponding     macro     is

+              in an array by bc(1); the  corresponding  macro  is
+              BC_DIM_MAX.
+
+       _SC_BC_SCALE_MAX
+              indicates the maximum scale value allowed by bc(1);
+              the corresponding macro is BC_SCALE_MAX.
+
+       _SC_BC_STRING_MAX

        BUGS
+
               It  is  difficult  use ARG_MAX because it is not specified
+       how much of the argument space for exec() is  consumed  by
+       the user's environment variables.
+
+       Some  returned  values  may be huge; they are not suitable
+       for allocating memory.
+
+       POSIX.2 is not yet an approved standard;  the  information
+       in this manpage is subject to change.

        TMPFILE(3)          Linux Programmer's Manual          TMPFILE(3)
+
        
+
+
        NAME
+
               tmpfile - create a temporary file
+
+
        SYNOPSIS
+
               #include <stdio.h>
+
+       FILE *tmpfile (void);
+
+
        DESCRIPTION
+
               The  tmpfile() function generates a unique temporary file-
+       name using the path prefix P_tmpdir defined in  <stdio.h>.
+       The  temporary  file  is  then opened in binary read/write
+       (w+b) mode.  The file will be automatically  deleted  when
+       it is closed or the program terminates.
+
+
        RETURN VALUE
+
               The  tmpfile()  function  returns  a stream descriptor, or
+       NULL if a unique  filename  cannot  be  generated  or  the
+       unique file cannot be opened.
+
+
        ERRORS
+
               EACCES Search  permission  denied  for directory in file's
+              path prefix.
+
+       EEXIST Unable to generate a unique filename.
+
+       EMFILE Too many file descriptors in use by process.
+
+       ENFILE Too many files open in system.
+
+       EROFS  Read-only filesystem.

        TMPNAM(3)           Linux Programmer's Manual           TMPNAM(3)
+
        
+
+
        NAME
+
               tmpnam - create a name for a temporary file
+
+
        SYNOPSIS
+
               #include <stdio.h>
+
+       char *tmpnam(char *s);
+
+
        DESCRIPTION
+
               The  tmpnam()  function generates a unique temporary file-
+       name using the path prefix P_tmpdir defined in  <stdio.h>.
+       If the argument s is NULL, tmpnam() returns the address of
+       an internal static area which holds the filename, which is
+       overwritten  by subsequent calls to tmpnam().  If s is not
+       NULL, the filename is returned in s.
+
+
        RETURN VALUE
+
               The tmpnam() function returns a pointer to the unique tem-
+       porary filename, or NULL if a unique name cannot be gener-
+       ated.
+
+
        ERRORS
+
               EEXIST Unable to generate a unique filename.

+       argument  that  is a pointer to a termios structure.  This
+       structure contains the following members:
+
+              tcflag_t c_iflag;      /* input modes */
+              tcflag_t c_oflag;      /* output modes */
+              tcflag_t c_cflag;      /* control modes */
+              tcflag_t c_lflag;      /* local modes */
+              cc_t c_cc[NCCS];       /* control chars */

+              characters preceded by  \.   On  output,  uppercase
+              characters  are preceded by \ and lowercase charac-
+              ters are converted to uppercase.
+
+       ECHO   echo input characters.
+
+       ECHOE  if ICANON is also set, the ERASE  character  erases
+              the  preceding  input  character, and WERASE erases
+              the preceding word.
+
+       ECHOK  if ICANON is also set, the  KILL  character  erases
+              the current line.
+
+       ECHONL if  ICANON  is also set, echo the NL character even
+              if ECHO is not set.
+
+       ECHOCTL
+              if ECHO is also set, ASCII  control  signals  other
+              than  TAB,  NL,  START,  and STOP are echoed as ^X,
+              where X is  the  character  with  ASCII  code  0x10
+              greater  than  the  control  signal.   For example,

+
+       ECHOPRT
+              if ICANON and IECHO are also  set,  characters  are
+              printed as they are being erased.
+
+       ECHOKE if  ICANON  is  also set, KILL is echoed by erasing
+              each character on the line, as specified  by  ECHOE
+              and ECHOPRT.
+
+       FLUSHO output  is  being flushed.  This flag is toggled by
+              typing the DISCARD character.
+
+       NOFLSH disable flushing the input and output  queues  when
+              generating  the  SIGINT  and  SIGQUIT  signals, and

+              SUSP signal.
+
+       TOSTOP send  the  SIGTTOU signal to the process group of a
+              background process which tries to write to its con-
+              trolling terminal.
+
+       PENDIN all  characters  in  the  input queue are reprinted
+              when the next character  is  read.   (bash  handles

+       ware that is not available)  from  the  termios  structure
+       referred to by termios_p.  optional_actions specifies when
+       the changes take effect:
+
+       TCSANOW
+              the change occurs immediately.
+
+       TCSADRAIN
+              the change occurs after all output  written  to  fd
+              has been transmitted.  This function should be used
+              when changing parameters that affect output.
+
+       TCSAFLUSH
+              the change occurs after all output written  to  the
+              object referred by fd has been transmitted, and all
+              input that has been received but not read  will  be
+              discarded before the change is made.
+
+       tcsendbreak() transmits a continuous stream of zero-valued
+       bits for a specific duration, if  the  terminal  is  using
+       asynchronous  serial  data  transmission.   If duration is
+       zero, it transmits zero-valued bits for at least 0.25 sec-
+       onds,  and  not more that 0.5 seconds.  If duration is not
+       zero, it sends zero-valued bits  for  duration*N  seconds,
+       where N is at least 0.25, and not more than 0.5.
+
+       If  the  terminal  is  not  using asynchronous serial data
+       transmission, tcsendbreak()  returns  without  taking  any
+       action.
+
+       tcdrain()  waits  until  all  output written to the object
+       referred to by fd has been transmitted.
+
+       tcflush() discards data written to the object referred  to
+       by  fd but not transmitted, or data received but not read,
+       depending on the value of queue_selector:
+
+       TCIFLUSH
+              flushes data received but not read.
+
+       TCOFLUSH
+              flushes data written but not transmitted.
+
+       TCIOFLUSH
+              flushes both data received but not read,  and  data
+              written but not transmitted.
+
+       tcflow() suspends transmission or reception of data on the
+       object referred to  by  fd,  depending  on  the  value  of
+       action:

+
+       TCOOFF suspends output.
+
+       TCOON  restarts suspended output.
+
+       TCIOFF transmits  a STOP character, which stops the termi-
+              nal device from transmitting data to the system.
+
+       TCION  transmits a START character, which starts the  ter-
+              minal device transmitting data to the system.
+
+       The default on open of a terminal file is that neither its
+       input nor its output is suspended.
+
+       The baud rate functions are provided for getting and  set-
+       ting  the values of the input and output baud rates in the
+       termios structure.  The new  values  do  not  take  effect
+       until tcsetattr() is successfully called.
+
+       Setting  the speed to B0 instructs the modem to "hang up".
+       The actual bit rate corresponding to B38400 may be altered
+       with setserial(8).
+
+       The  input and output baud rates are stored in the termios
+       structure.
+
+       cfgetospeed() returns the output baud rate stored  in  the
+       termios structure pointed to by termios_p.
+
+       cfsetospeed()  sets  the  output  baud  rate stored in the
+       termios structure pointed to by termios_p to speed,  which
+       must be one of these constants:
+            B0
+            B50
+            B75

+            B230400
+       The  zero  baud rate, B0, is used to terminate the connec-
+       tion.  If B0 is specified, the modem control  lines  shall
+       no longer be asserted.  Normally, this will disconnect the

               toupper, tolower - convert letter to upper or lower case
+
+
        SYNOPSIS

+       int toupper (int c);
+       int tolower (int c);
+
+
        DESCRIPTION
+
               toupper()  converts  the letter c to upper case, if possi-
+       ble.
+
+       tolower() converts the letter c to lower case,  if  possi-
+       ble.
+
+
        RETURN VALUE
+
               The  value  returned is that of the converted letter, or c
+       if the conversion was not possible.

        BUGS
+
               The details of what constitutes an uppercase or  lowercase
+       letter  depend  on  the  current locale.  For example, the
+       default "C" locale does not know about umlauts, so no con-
+       version is done for them.
+
+       In some non - English locales, there are lowercase letters
+       with no corresponding  uppercase  equivalent;  the  German
+       sharp s is one example.

        NAME
+
               fgetc, fgets, getc, getchar, gets, ungetc - input of char-
+       acters and strings
+
+
        SYNOPSIS
+
               #include <stdio.h>
+
+       int fgetc(FILE *stream);
+       char *fgets(char *s, int size, FILE *stream);
+       int getc(FILE *stream);
+       int getchar(void);
+       char *gets(char *s);
+       int ungetc(int c, FILE *stream);
+
+
        DESCRIPTION
+
               fgetc() reads the next character from stream  and  returns
+       it  as  an  unsigned char cast to an int, or EOF on end of
+       file or error.
+
+       getc() is equivalent to fgetc()  except  that  it  may  be
+       implemented  as  a  macro which evaluates stream more than
+       once.
+
+       getchar() is equivalent to getc(stdin).
+
+       gets() reads a line from stdin into the buffer pointed  to
+       by  s  until either a terminating newline or EOF, which it
+       replaces with '\0'.  No check for buffer overrun  is  per-
+       formed (see BUGS below).
+
+       fgets()  reads  in at most one less than n characters from
+       stream and stores them into the buffer pointed  to  by  s.
+       Reading  stops after an EOF or a newline.  If a newline is
+       read, it is stored into the  buffer.   A  '\0'  is  stored
+       after the last character in the buffer.
+
+       ungetc()  pushes  c back to stream, cast to unsigned char,
+       where it is  available  for  subsequent  read  operations.
+       Pushed  -  back  characters  will  be  returned in reverse
+       order; only one pushback is guaranteed.
+
+       Calls to the functions described here can  be  mixed  with
+       each  other  and  with calls to other input functions from
+       the stdio library for the same input stream.
+
+
        RETURN VALUES
+
               fgetc(), getc() and getchar() return the character read as
+       an  unsigned  char cast to an int or EOF on end of file or
+       error.
+
+       gets() and fgets() return s on success, and NULL on end of
+       file or error.
+
+       ungetc() returns c on success, or EOF on error.

        BUGS
+
               Because  it is impossible to tell without knowing the data
+       in advance how  many  characters  gets()  will  read,  and
+       because  gets() will continue to store characters past the
+       end of the buffer, it is extremely dangerous to  use.   It
+       has  been  used  to  break computer security.  Use fgets()
+       instead.
+
+       It is not advisable to mix calls to input  functions  from
+       the stdio library with low - level calls to read() for the
+       file descriptor associated  with  the  input  stream;  the
+       results  will  be undefined and very probably not what you
+       want.

        UNLINK(2)           Linux Programmer's Manual           UNLINK(2)
+
        
+
+
        NAME
+
               unlink - delete a name and possibly the file it refers to
+
+
        SYNOPSIS
+
               #include <unistd.h>
+
+       int unlink(const char *pathname);
+
+
        DESCRIPTION
+
               unlink  deletes  a  name from the filesystem. If that name
+       was the last link to a file and no processes have the file
+       open  the  file  is  deleted and the space it was using is
+       made available for reuse.
+
+       If the name was the last link to a file but any  processes
+       still have the file open the file will remain in existence
+       until the last file descriptor referring to it is  closed.
+
+       If  the  name  referred  to  a  symbolic  link the link is
+       removed.
+
+       If the name referred to a socket, fifo or device the  name
+       for it is removed but processes which have the object open
+       may continue to use it.
+
+
        RETURN VALUE
+
               On success, zero is returned.  On error, -1  is  returned,
+       and errno is set appropriately.
+
+
        ERRORS
+
               EFAULT  pathname  points  outside  your accessible address
+               space.
+
+       EACCES  Write access to the directory containing  pathname
+               is not allowed for the process's effective uid, or
+               one of the directories in pathname did  not  allow
+               search (execute) permission.
+
+       EPERM   The  directory containing pathname has the sticky-
+               bit (S_ISVTX) set and the process's effective  uid
+               is  neither  the uid of the file to be deleted nor
+               that of the directory containing it.
+
+       ENAMETOOLONG
+               pathname was too long.
+
+       ENOENT  A directory component in pathname does  not  exist
+               or is a dangling symbolic link.
+
+       ENOTDIR A  component  used  as  a directory in pathname is
+               not, in fact, a directory.
+
+       EISDIR  pathname refers to a directory.

+
        
+
+
        NAME
+
               setenv - change or add an environment variable
+
+
        SYNOPSIS
+
               #include <stdlib.h>
+
+       int setenv(const char *name, const char *value, int overwrite);
+
+       void unsetenv(const char *name);
+
+
        DESCRIPTION
+
               The  setenv() function adds the variable name to the envi-
+       ronment with the value value, if  name  does  not  already
+       exist.   If  name  does exist in the environment, then its
+       value is changed to value if  overwrite  is  non-zero;  if
+       overwrite  is zero, then the value of name is not changed.
+
+       The unsetenv() function deletes the variable name from the
+       environment.
+
+
        RETURN VALUE
+
               The  setenv()  function  returns zero on success, or -1 if
+       there was insufficient space in the environment.

        STDARG(3)           Linux Programmer's Manual           STDARG(3)
+
        
+
+
        NAME
+
               stdarg - variable argument lists
+
+
        SYNOPSIS
+
               #include <stdarg.h>
+
+       void va_start( va_list ap, last);
+       typeva_arg( va_list ap, type);
+       void va_end( va_list ap);
+
+
        DESCRIPTION
+
               A  function  may  be called with a varying number of argu-
+       ments  of  varying  types.   The  include  file   stdarg.h
+       declares a type va_list and defines three macros for step-
+       ping through a list of arguments whose  number  and  types
+       are not known to the called function.
+
+       The called function must declare an object of type va_list
+       which is used by the macros va_start, va_arg, and  va_end.
+
+       The  va_start  macro  initializes ap for subsequent use by
+       va_arg and va_end, and must be called first.
+
+       The parameter last is  the  name  of  the  last  parameter
+       before  the variable argument list, i.e., the last parame-
+       ter of which the calling function knows the type.
+
+       Because the address of  this  parameter  is  used  in  the
+       va_start  macro,  it  should not be declared as a register
+       variable, or as a function or an array type.
+
+       The va_start macro returns no value.
+
+       The va_arg macro expands to an  expression  that  has  the
+       type  and  value  of  the  next argument in the call.  The
+       parameter ap is the va_list ap  initialized  by  va_start.
+       Each  call  to  va_arg  modifies  ap so that the next call
+       returns the next argument.  The parameter type is  a  type
+       name  specified so that the type of a pointer to an object
+       that has the specified type  can  be  obtained  simply  by
+       adding a * to type.
+
+       If there is no next argument, or if type is not compatible
+       with the type of the actual  next  argument  (as  promoted
+       according  to  the  default  argument  promotions), random
+       errors will occur.
+
+       The first use of  the  va_arg  macro  after  that  of  the
+       va_start  macro  returns the argument after last.  Succes-
+       sive invocations return the values of the remaining  argu-
+       ments.
+
+       The va_end macro handles a normal return from the function
+       whose variable argument list was initialized by  va_start.

        EXAMPLES
+
               The  function  foo takes a string of format characters and
+       prints out the argument associated with each format  char-
+       acter based on the type.
+              void foo(char *fmt, ...)
+              {
+                   va_list ap;
+                   int d;
+                   char c, *p, *s;
+
+                   va_start(ap, fmt);
+                   while (*fmt)
+                        switch(*fmt++) {
+                        case 's':           /* string */
+                             s = va_arg(ap, char *);
+                             printf("string %s\n", s);
+                             break;
+                        case 'd':           /* int */
+                             d = va_arg(ap, int);
+                             printf("int %d\n", d);
+                             break;
+                        case 'c':           /* char */
+                             c = va_arg(ap, char);
+                             printf("char %c\n", c);
+                             break;
+                        }
+                   va_end(ap);
+              }
+
+
        STANDARDS
+
               The  va_start,  va_arg,  and va_end macros conform to ANSI
+       C3.159-1989 (``ANSI C'').
+
+
        COMPATIBILITY
+
               These macros are not compatible with the  historic  macros
+       they  replace.  A backward compatible version can be found
+       in the include file varargs.h.
+
+
        BUGS
+
               Unlike the varargs macros, the stdarg macros do not permit
+       programmers  to  code  a function with no fixed arguments.
+       This problem generates work mainly when converting varargs
+       code  to stdarg code, but it also creates difficulties for
+       variadic functions that wish to pass all  of  their  argu-
+       ments on to a function that takes a va_list argument, such
+       as vfprintf(3).

        NAME
+
               printf,  fprintf,  sprintf,  vprintf, vfprintf, vsprintf -
+       formatted output conversion
+
+
        SYNOPSIS
+
               #include <stdio.h>
+
+       int printf( const char *format, ...);
+       int fprintf( FILE *stream, const char *format, ...);
+       int sprintf( char *str, const char *format, ...);
+
+       #include <stdarg.h>
+
+       int vprintf( const char *format, va_list ap);
+       int vfprintf( FILE *stream, const  char  *format,  va_list
+       ap);
+       int vsprintf( char *str, char *format, va_list ap);
+
+
        DESCRIPTION
+
               The  printf  family of functions produces output according
+       to a format as described below.  Printf and vprintf  write
+       output  to stdout, the standard output stream; fprintf and
+       vfprintf write output to the given output stream; sprintf,
+       and  vsprintf  write  to  the character string str.  These
+       functions write the output under the control of  a  format
+       string  that  specifies how subsequent arguments (or argu-
+       ments accessed via the variable-length argument facilities
+       of  stdarg(3)  are  converted for output.  These functions
+       return the number of characters printed (not including the
+       trailing `\0' used to end output to strings).
+
+       The  format string is composed of zero or more directives:
+       ordinary characters (not %), which are copied unchanged to
+       the  output stream; and conversion specifications, each of
+       which results in fetching zero or  more  subsequent  argu-
+       ments.  Each conversion specification is introduced by the
+       character  %.   The  arguments  must  correspond  properly
+       (after  type  promotion)  with  the  conversion specifier.
+       After the %, the following appear in sequence:
+
+       o      Zero or more of the following flags:
+
+              #      specifying that the  value  should  be  con-
+                     verted  to an ``alternate form''.  For c, d,
+                     i, n, p, s, and u conversions,  this  option
+                     has  no effect.  For o conversions, the pre-
+                     cision of the number is increased  to  force
+                     the  first character of the output string to
+                     a zero (except if a zero  value  is  printed
+                     with  an explicit precision of zero).  For x
+                     and X conversions, a non-zero result has the
+                     string  `0x'  (or  `0X'  for  X conversions)
+                     prepended to it.  For e, E, f, g, and G con-
+                     versions,  the  result will always contain a

+                     results of those conversions only if a digit
+                     follows).  For g and G conversions, trailing
+                     zeros are not removed  from  the  result  as
+                     they would otherwise be.

+                     padded  on  the  left with zeros rather than
+                     blanks.  If a  precision  is  given  with  a
+                     numeric  conversion  (d,  i, o, u, i, x, and
+                     X), the 0 flag is ignored.

+                     sions,  the converted value is padded on the
+                     right with blanks, rather than on  the  left
+                     with  blanks or zeros.  A - overrides a 0 if

+                     (a space) specifying that a blank should  be
+                     left  before a positive number produced by a
+                     signed conversion (d, e, E, f, g, G, or  i).
+
+              +      specifying  that  a  sign  always  be placed
+                     before a number produced by a signed conver-
+                     sion.   A  +  overrides  a space if both are
+                     used.
+
+       o      An optional decimal digit string specifying a mini-
+              mum  field width.  If the converted value has fewer
+              characters than the field width, it will be  padded
+              with  spaces  on  the  left (or right, if the left-
+              adjustment flag has been given)  to  fill  out  the
+              field width.
+
+       o      An  optional  precision,  in  the  form of a period
+              (`.')  followed by an optional  digit  string.   If
+              the digit string is omitted, the precision is taken
+              as zero.  This gives the minimum number  of  digits
+              to appear for d, i, o, u, x, and X conversions, the
+              number of digits to appear after the  decimal-point
+              for  e, E, and f conversions, the maximum number of
+              significant digits for g and G conversions, or  the
+              maximum  number  of characters to be printed from a
+              string for s conversions.
+
+       o      The optional character h, specifying that a follow-
+              ing d, i, o, u, x, or X conversion corresponds to a
+              short int or unsigned short int argument, or that a
+              following  n conversion corresponds to a pointer to

+              a pointer to a long int or unsigned long int  argu-

+              f,  g, or G conversion corresponds to a long double
+              argument.
+
+       o      A character that specifies the type  of  conversion
+              to be applied.
+
+       A  field  width or precision, or both, may be indicated by
+       an asterisk `*' instead of a digit string.  In this  case,
+       an  int argument supplies the field width or precision.  A
+       negative field width is treated as a left adjustment  flag
+       followed  by  a positive field width; a negative precision
+       is treated as though it were missing.
+
+       The conversion specifiers and their meanings are:
+
+       diouxX The int (or appropriate variant) argument  is  con-
+              verted  to signed decimal (d and i), unsigned octal
+              (o, unsigned decimal (u, or unsigned hexadecimal (x
+              and X) notation.  The letters abcdef are used for x
+              conversions; the letters ABCDEF are used for X con-
+              versions.  The precision, if any, gives the minimum
+              number of digits that must appear; if the converted
+              value  requires  fewer  digits, it is padded on the
+              left with zeros.
+
+       DOU    The long int argument is converted to signed  deci-
+              mal, unsigned octal, or unsigned decimal, as if the
+              format had been ld, lo, or lu respectively.   These
+              conversion  characters  are  deprecated,  and  will
+              eventually disappear.
+
+       eE     The double argument is rounded and converted in the
+              style  [-]d.dddedd  where there is one digit before
+              the decimal-point character and the number of  dig-
+              its after it is equal to the precision; if the pre-
+              cision is missing, it is taken as 6; if the  preci-
+              sion  is  zero, no decimal-point character appears.
+              An E conversion uses the letter E (rather  than  e)
+              to  introduce  the  exponent.   The exponent always
+              contains at least two digits; if the value is zero,
+              the exponent is 00.
+
+       f      The  double  argument  is  rounded and converted to
+              decimal notation in the style [-]ddd.ddd, where the
+              number  of digits after the decimal-point character
+              is equal to the precision  specification.   If  the
+              precision  is  missing,  it  is  taken as 6; if the

+
        
+
+              precision  is  explicitly  zero,  no  decimal-point
+              character  appears.  If a decimal point appears, at
+              least one digit appears before it.
+
+       g      The double argument is converted in style  f  or  e
+              (or  E for G conversions).  The precision specifies
+              the number of significant digits.  If the precision
+              is missing, 6 digits are given; if the precision is
+              zero, it is treated as 1.  Style e is used  if  the
+              exponent  from  its  conversion  is less than -4 or
+              greater than or equal to the  precision.   Trailing
+              zeros  are  removed from the fractional part of the
+              result; a decimal point appears only if it is  fol-
+              lowed by at least one digit.
+
+       c      The  int argument is converted to an unsigned char,
+              and the resulting character is written.
+
+       s      The ``char *'' argument is expected to be a pointer
+              to  an  array  of  character  type  (pointer  to  a
+              string).  Characters from the array are written  up
+              to (but not including) a terminating NUL character;
+              if a precision is specified, no more than the  num-
+              ber  specified  are  written.   If  a  precision is
+              given, no null character need be  present;  if  the
+              precision  is not specified, or is greater than the
+              size of the array, the array must contain a  termi-
+              nating NUL character.
+
+       p      The  ``void *'' pointer argument is printed in hex-
+              adecimal (as if by %#x or %#lx).
+
+       n      The number of characters written so far  is  stored
+              into  the  integer  indicated  by the ``int *'' (or
+              variant) pointer argument.   No  argument  is  con-
+              verted.
+
+       %      A  `%'  is  written.  No argument is converted. The
+              complete conversion specification is `%%'.
+
+       In no case does a non-existent or small field width  cause
+       truncation  of  a  field; if the result of a conversion is
+       wider than the field width, the field is expanded to  con-
+       tain the conversion result.
+
+
+
        EXAMPLES

+       10:02', where weekday and month are pointers to strings:

        STANDARDS
+
               The  fprintf,  printf,  sprintf,  vprintf,  vfprintf,  and
+       vsprintf  functions  conform  to  ANSI C3.159-1989 (``ANSI
+       C'').
+
+
        BUGS
+
               Some floating point conversions under Linux  cause  memory
+       leaks.
+
+       The conversion formats %D, %O, and %U are not standard and
+       are provided only for backward compatibility.   These  may
+       not be provided under Linux.
+
+       The  effect of padding the %p format with zeros (either by
+       the 0 flag or by specifying a precision), and  the  benign
+       effect  (i.e.,  none)  of  the # flag on %n and %p conver-
+       sions, as well as other nonsensical combinations  such  as
+       %Ld,   are  not  standard;  such  combinations  should  be
+       avoided.
+
+       Because sprintf and vsprintf  assume  an  infinitely  long
+       string, callers must be careful not to overflow the actual
+       space; this is often impossible to assure.

        NAME
+
               wctomb  -  convert a wide character to a multibyte charac-
+       ter.
+
+
        SYNOPSIS
+
               #include <stdlib.h>
+
+       int wctomb(char *s, wchar_t wchar);
+
+
        DESCRIPTION
+
               The wctomb() function converts a wide character wchar into
+       a  multibyte  character  and, if s is not NULL, stores the
+       multibyte character representation in s.
+
+
        RETURN VALUE
+
               wctomb() returns the number  of  bytes  in  the  multibyte
+       character or -1 if the wide character is not valid.

        Input and Output
         
+
        
+
        
+
        
+The C language does not have any I/O capability! You can access 
+files and devices via two groups of functions, these can be split
+as shown below.
        
+
+
        
+
+
        Low Level I/O
        
+
+Low level functions provide direct access to files and devices. If you
+only need file read and write you should use the 
+        ANSI functions as your code will remain portable.
+If you want to access things like, serial ports, virtual memory and 
+tape drives, low level I/O is for you.
        
+
+Low level functions reference files by a 
+file descriptor, this descriptor 
+is created with the open function and
+can be referenced by functions like:
        
+close
        
+read
        
+write
        
+mmap - Memory map (Not supported on Linux).
        
+ioctl I/O control.
        
+
+Three 'file descripters' are opened automatically when your program runs.
+These are:
+
        +	File		Default
+	Desc	Name	device
+	----    ----	------
+	0	stdin	Keyboard
+	1	stdout	Screen
+	2	stderr	Screen
+
        
+
+If you want to use these 'file descriptors', you do not have to issue an 
+'open'.
+
+
+
+
        ANSI standard functions
        
+
+These functions are defined in the 
+        stdio.h header.
+
+The important thing to remember with these functions is the data 
+is presented in a consistant manor across all platforms. A record
+is considered to be 0 or more characters followed by a 
+newline character.
+If the actual (physical) record is terminated in some other way, the 
+functions will perform the conversion for you.
+

+Link Lists

        Link Lists
         
        
+
        
+
        
+
        
+
+
+Question, how would you write a program to meet the following requirements?
+
+
          
+
        1. Read an unknown number of records from a file into memory. A typical
+record would look like:
+
          +	Ref  Title	  Cost
+	---  -----	  ----
+	1234 Oracle_Guide 22.95
+
          
+
        2. Perform a numeric sort based on the first field.
+
        3. Delete duplicate records based on the first field.
+
        
+
+One method is to define an 
+        array of records as below:
+
+
        +	main()
+ 	{
+	  char array[50][80]; /* 50 records, 80 bytes long	*/
+	}
+
        
+
+The data can then be read into the array and then actions performed 
+on the data.
+This is OK but has some major problems.
+
          
+
        1. The arrary will hold all the data in character format. It would be 
+nice to hold the integer and decimal numbers in a more appropriate form.
+
        2. If you have more than 50 records the program has to be altered
+and recompiled.
+
        
+The first problem could be fixed by defining an 
+array of structures BUT both problems 
+can be solved with linked lists.
        
+
+
+
+
+
        
+The concept of a linked list is fairly simple. It is a group of structures
+linked together by pointers, here is a picture:
        
+
        
+
        
+
        
+The "Name Age Pointer" block could be defined as below:
+
        +	struct record {char name[20]; int age; struct record *next_rec;}; 
+
        
+
+The important bit is "struct record *next_rec" this is the pointer to the next
+structure (record). It will either point to the next record which 
+will require memory reserved 
+with the malloc function or
+NULL if  its the last record.
+
        
+
+
        Examples
        
+
+
+ Here is the first example. 
+This program is more complicated than I would 
+like, but its the simplest I can come up with. 
+
        
+
        
+

        stderr
        
+
+stderr also writes to the screen. If you are using a Unix based system

+ *	    display on the right.

+ * Bugs:    If the last line of the dump is full, the program will

+ *	    but you are welcome to fix it.
+ *
+ * To do:   o Highlight '0A' (end of line) - seems like a good idea.

+ *	    o Remove the directory info from argv[0] (if present).

+
+
        
+Random numbers. Produce a sequence of six random numbers between 1 and
+49. These can then be used to play the National lottery (in England). The
+odds on getting the right numbers are 13,983,816 to 1 - GOOD LUCK SUCKER.
        
+
+
        
+Answer should look like:
        
+

        The break statement.

        +
        +
        +

        +This statement allows the program to escape from for, +while, +do ... while loops and switch structures. +

        + +It should NOT be used to escape from an if block. +

        + +The COMMA. + + + + +

        +

        The COMMA.

        +
        +The comma has two uses. The most comman, is as a parameter seperator +for data types and +function parameter lists. +Here is an example: +
        +	main()
+    	{
+	   char String1[20], String2[]="Outback Pub"; /* data types */
+	   strncpy(String1, string2, 7);
+	}
+
        +The other use is as a series operator which can be seen in use with +the for keyword. An example of the syntax is shown +in the link below. + +
        +

        Examples:

        + + +Comments. + + + + +

        +
        +

        Comments.

        +
        +
        +

        +Lets start with a few examples. +

        +

        + + + + +
        +
        +
+  main()
+  {
+
+      int Counter=0;       /* Initalise Counter */
+
+      /* a comment */
+
+      /*
+       * Another comment
+       */
+
+      /*****************
+       *
+       * Final comment.
+       *
+       *****************/ 
+  }
+
        +
        +
        +

        +

        +

        +A comment starts with a /* and +ends with */. Comments started in this way can span multiple +lines but cannot be nested. +For example: +

        +

        + + + + +
        +
        +
+   main()
+   {
+       int Count = 0;           /* Initalise 
+                                 * Counter to 0 */
+
+       /* /* Invalid comment */ */
+   }
+
        +
        +
        +

        +This will give a syntax error, because the last line +contains nested comments. + +C++ offers a solution to +comment nesting. + +

        +

        The const keyword.

        +
        +
        + +The const keyword is used to create a read only variable. Once initialised, +the value of the variable cannot be changed but can be used just like +any other variable. + +

        const syntax

        +

        +

        + + +
        +
        +
+        main()
+        {
+            const float pi = 3.14; 
+        }
+
        +
        +
        +

        +The const keyword is used as a qualifier to the following data types - +int float char double struct. +

        +

        + + +
        +
        +
+        const int   degrees = 360; 
+        const float pi      = 3.14; 
+        const char  quit    = 'q';

        +
        +
        +

        +

        const and pointers.

        + +Consider the following example. +

        +

        + + +
        +
        +
+        void Func(const char *Str);
+
+        main()
+        {
+            char *Word;
+
+            Word = (char *) malloc(20);
+
+            strcpy(Word, "Sulphate");
+          
+            Func(Word);
+        }
+        
+        void Func(const char *Str)
+        {
+        }
+
        +
        +
        +

        +The const char *Str tells the compiler that the DATA the +pointer points too is const. This means, Str can be changed +within Func, but *Str cannot. As a copy of the pointer is passed to Func, +any changes made to Str are not seen by main.... + +

        +

        + + +
        +
        +

+           | *Str   | Read Only - Cannot be changed.

        Geeky Stuff

        + +It is still possible to change the contents of a 'const' variable. +Consider this program it creates +a const variable and then changes its value by accessing the data by +another name. +

        +I am not sure if this applies to all compilers, but, +you can place the 'const' after the datatype, for example: +

        +

        + + +
        +
        +
+        int   const degrees = 360; 
+        float const pi      = 3.14; 
+        char  const quit    = 'q'; 
+
        + +
        +
        +

        +are all valid in 'gcc'. +

        +

        More Geeky Stuff

        + +What would you expect these to do? +

+        };

        +
        +

        +ENUM is closely related to the #define +preprocessor.

        Basic principles

        +Say you wanted to print all the numbers between 1 and 10, you could write: +

+        {
+	   int count=1;

+	   printf("%d\n", count++);
+	   printf("%d\n", count++);
+        }
+
        + +As you can see this program would NOT be very practical if we wanted +1000 numbers. The problem can be solved with the for statement +as below. +
        +	main()

        count=1 +
        is the initalisation.

        + +

        printf("%d\n", count) +

        +

        + + +
        +

        Repeating several lines of code

        + +The previous example showed how to repeat ONE statement. This example +shows how many lines can be repeated. + +
        +	main()
+        {

+        }
+
        + +The { and } following the for statement define +a         block of statements. + + +
        +

        More detail

        + +The for statement performs the following functions while looping. + +
        +	for (expression_1 ; expression_2 ; expression_3) statement ;
+
        +
          +
        1. Executes expression_1.

          +

        2. Executes statement. +
        3. Executes expression_3. +
        4. Evaluates expression_2. +

          +

            +
          • If TRUE, Jumps to item 2. +
          • If FALSE, Stops looping. +
          +
        + +Any of the three expressions can be missing, if the first or third is missing, +it is ignored. If the second is missing, is is assumed to be TRUE.

        + +The following example is an infinite loop: + +

        Passing pointers.

        +This is known as call by reference and is an area worth spending some +time on. We do not pass the data to the function, instead we pass a pointer +to the data. This means that if the function alters the data, the original +is altered.

        +

        Returning values.

        + +Normally you would return an 'int', 'char', 'float', or 'double' using this +technic. The obvious time to return a value would be to return a completion +code. +

        +Here is an example +

        +The contents of 'c' are copied into 'i'. + +

        Returning pointers.

        + +Returning values is OK for the data types above but not very practical for +'char *' or structures. For these data types passing pointers can be more +appropriate. When using these pointers it is important to understand the +'static' storage class +otherwise you are going to get some unpredictable +results. + +

        + +

        Local variables

        +Local variables must always be +defined +at the top of a block. +

        + +C++ has changed the rules regarding where you can define a +local variable. +Click here +for the low down. + +

        +When a local variable is +defined +- it is not initalised by the system, you +must initalise it yourself.

        +A local variable is +defined + inside a block and is only visable +from within the block. +

        +

        + + + + +
        +
        +
+   main()
+   {
+       int i=4;
+       i++;
+   }
+
+
        +
        +
        +

        +When execution of the block starts the variable is +available, and when the block ends the variable 'dies'.

        +A local variable is visible within nested blocks unless a variable with +the same name is +defined + within the nested block. +

        +

        + + + + +
        +
        +
+   main()
+   {
+       int i=4;
+       int j=10;
+       
+       i++;
+      
+       if (j > 0)
+       {
+          printf("i is %d\n",i);      /* i defined in 'main' can be seen      */
+       }
+     
+       if (j > 0)
+       {
+          int i=100;                  /* 'i' is defined and so local to 
+                                       * this block */
+          printf("i is %d\n",i);      
+       }                              /* 'i' (value 100) dies here            */
+     
+       printf("i is %d\n",i);         /* 'i' (value 5) is now visable.        */
+   }

        Global variables

        + + +C++ has enhanced the use of +         global variables. + +

        +Global variables ARE initalised by the system when you +define + them! +

        +

        + + + + + + + +
        Data Type Initialser
        int 0
        char '\0'
        float 0
        pointer NULL
        +
        +

        +In the next example i is a global variable, it can be seen and modified by + main and any other functions that may reference it. +

        +

        + + + + +
        +
        +
+   int i=4;
+   
+   main()
+   {
+       i++;
+   }
+
+
        +
        +
        +

        + +Now, this example has global and Internal variables. +

        +

        + + + + +
        +
        +
+   int i=4;          /* Global definition   */
+   
+   main()
+   {
+       i++;          /* global variable     */
+       func
+   }
+
+   func()
+   {
+       int i=10;     /* Internal declaration */
+       i++;          /* Internal variable    */
+   }
+
+
        +
        +
        +

        + +i in main is global and will be incremented to 5. i in +func is internal and will be incremented to 11. When control returns +to main the internal variable will die and and any reference to +i will +be to the global.

        + + +static variables can be 'seen' within all functions in this source file. At +link time, the static variables defined here will not be seen by the object +modules that are brought in.

        The 'if' and 'else' keywords

        +
        +
        +

        + +The if-else statement is a two-way decision statement. It is written as + +

        +	if ( expression )	statement1;
+	[else			statement2;]
+
        + +The else portion is optional. If the expression evaluates to +true +(anything other than 0) then statement1 is executed. If there is an else +statement and the expression evaluates to +false +statement2 is executed. + +For example + +
        +(1)
+	int NumberOfUsers;
+	.
+	.
+	if( NumberOfUsers == 25 )
+        {				/* No else part */
+	  printf( "There are already enough users. Try later.\n" );
+	  return ERROR;
+        }
+	.
+	.
+
+
+(2)	if( a >= b )	larger = a;	/* else part is present */
+	else		larger = b;
+
        + +Consider this code fragment: +
        +	if( p == 1 )
+	  if( q == 2 )	r = p * 2 + q;
+        else r = q * 2 + p;
+
        +Because the else part is optional, there is an ambiguity when an else is +omitted from a nested if sequence. In 'C', this is resolved by associating +the else with the closest previous if that does not have an else. +Therefore, in the above example, the else part belongs to the if(q==2) +statement. + +The code can be made more readable by explicitly putting parentheses in +the expression, like this + +
        +	if( p == 1 )
+        {
+	  if( q == 2 )	r = p * 2 + q;
+        }
+	else r = q * 2 + p;
+
+		OR
+
+	if( p == 1 )
+        {
+	  if( q == 2 )	r = p * 2 + q;
+	  else r = q * 2 + p;
+        }
+
        + +Because the statement in the else part can also be an if statement, a +construct such as shown below is possible in 'C' to create a multiple +choice construct. + +
        +	if( expression1 )
+	  statement1;
+	else if( expression2 )
+	  statement2;
+	else if( expression3 )
+	  statement3;
+	.
+	.
+	else
+	  statementN;

        Logical AND

        +For Example: +

        +	/* These all return TRUE (1) */
+
+	if (4 && 5) return();
+
+	i=3;

+	return( i && j);

        +The expression is evaluated 'Left to Right' If any part of the expression +returns ZERO - The evaluation ends. +

        +THIS CAN CAUSE SERIOUS PROBLEMS. +

        +For example: +

        +	k=0;
+	i=3;
+	j=2;
+	if ( i-i && j++) k=1
+
        +The left side (i-i) resolves to 0, so j is not incremented +and k is not changed. +
        +         +

        Logical OR

        +OR also evaluates 'Left to Right' and will stop when an expression +returns true.

        +         +

        Logical NOT

        + +NOT reverses the logical state of its +        operand. If the operand is 0, 1 is +returned, else 0 is returned. + +

        Notes:

        +
          +
        • The value passed to SQUARE could have been an +int +float +or +double +
        • Long macros can span multiple lines by using a +\ followed by a newline +(return). +
        • If you are using gcc to compile your code, you can use the -E option to +see the preprocessor output +

        NULL

        +
        +

        +NULL is used in several ways. +

          +
        • As a pointer to address zero. NULL is defined in several ANSI headers +as the +symbolic constant +(void *)0. Zero is often returned from +functions that normaly return a pointer to signal an error. It is therefore +conveniant to compare a function return code with NULL to catch errors. +
          +	if ((fp=fopen("/etc/hosts","r") == NULL)
+        {
+          exit(0);
+        }
+
          +

          +

        • To mark the end of a character string. A null character is used to +terminate the string. For example if you coded: +
          +	char * text="abc";
+
          +You will actually reserve FOUR bytes containing in ASCII hex. +
          +	61 62 63 00
+	 a  b  c \0
+
          +The null at the end can be coded by using the +escape sequence '\0'. +
        +

        +\0 is actually an octal escape sequence, +strictly speeking it should +be written as \000 +

        +

        +

        ANSI headers

        +The following headers define NULL. +
          +
        • locale.h +
        • stddef.h +
        • stdio.h +

          +return will return a value from a function to its caller. +The value returned is +the result of an expression. +

        Notes:

        +For some reason, static has different +meanings in in different contexts. +
          +
        1. When specified on a function declaration, it makes the +function local to the file. +

          +

        2. When specified with a variable inside a function, it +allows the vairable to retain its value between calls to +the function. See +static variables. +
        +It seems a little strange that the same keyword has such +different meanings.... + +

        C Storage Classes.

        +
        +
        +

        +C has a concept of 'Storage classes' which are used to define the +scope (visability) and life time of variables and/or functions. +

        +So what Storage Classes are available? +

        + + + +
        auto +register +static +extern +typedef +
        +

        +

        +

        auto - storage class

        +auto is the default storage class for local variables. +
        +	{
+            int Count;
+            auto int Month;
+	}
+
        + +The example above defines two variables with the same storage class. +auto can only be used within functions, i.e. local variables.

        +

        +

        register - Storage Class

        +register is used to define local variables that should be stored +in a register instead of RAM. This means that the variable has a maximum size +equal to the register size (usually one word) and cant have the unary '&' +operator applied to it (as it does not have a memory location). +
        +	{
+            register int  Miles;
+	}
+
        +Register should only be used for variables that require quick access - such +as counters. It should also be noted that defining 'register' goes not mean +that the variable will be stored in a register. It means that it MIGHT be stored +in a register - depending on hardware and implimentation restrictions.

        +

        +

        static - Storage Class

        +static is the default storage class for global variables. The two +variables below (count and road) both have a static storage class. +
        +	static int Count;
+        int Road;
+
+        {
+            printf("%d\n", Road);
+        }
+
        +static variables can be 'seen' within all functions in this source file. At +link time, the static variables defined here will not be seen by the object +modules that are brought in.

        +'static' can also be defined within a function! If this is done the variable +is initalised at run time but is not reinitalized when the function is called. +This is serious stuff - tread with care. + +

        +	{
+	    static Count=1;
+        }
+
        +Here is an         example

        + + +There is one very important use for 'static'. Consider this bit of code. +

        +        char *func(void);
+
+        main()
+        {
+            char *Text1;
+            Text1 = func();
+        }
+
+        char *func(void)
+        {
+            char Text2[10]="martin";
+            return(Text2);
+        }
+
        + +Now, 'func' returns a pointer to the memory location where 'text2' starts +BUT text2 has a storage class of 'auto' and will disappear when we exit the +function and could be overwritten but something else. The answer is to specify +
        +	static char Text[10]="martin";
+
        +The storage assigned to 'text2' will remain reserved for the duration if the +program. +

        +

        + +C++ has overloaded static,         here +are the details. + +
        +

        extern - storage Class

        +extern defines a global variable that is visable to ALL object +modules. When you use 'extern' the variable cannot be initalized as +all it does is point the variable name at a storage location that has +been previously defined. + + + + + + + + +

        STRUCT keyword

        +
        +

        + +

        + + +
        +

        Structure basics

        + +struct is used to declare a new +        data-type. +Basically this means +grouping variables together. For example, a struct data type could be used +to declare the format of the following file.

        + +

        + + +
        +
                  
+   Jo		Loss		Maths		A   
+   Harry	Carpenter	English 	A
+   Billy	King		Maths		C
+
        +
        +
        +

        + +The records above could be described in a struct as follows: +

        +

        + + +
        +
           
+
+   struct
+   {
+       char cname[8];
+       char sname[16];   
+       char exam[16];
+       char grade;
+   } record;
+
+
        +
        +
        +

        +The statement above declares a variable called record with 4 members +called cname, sname, exam, grade. The structure as a whole can be +referred to as record and a member can be referenced as +record.exam +

        + +Structures can be declared in various forms... +

        + +

        +	struct x {int a; int b; int c;};		/* declaration	*/
+	struct 	 {int a; int b; int c;} z;
+	struct x z;
+
        +All the examples above are structure declarations, +
          +
        • The first gives x as a 'structure tag' - this is optional. +
        • The first and second declare the members of the structure. +
        • Second and third give z this is the variable that assumes the +structure type. +
        +

        + + +

        +

        Structure membership

        + +We can access individual members of a structure with the . operator.

        +For example to assign a value, we can enter: +

        +

        + + +
        +
        +	
+   struct x {int a; int b; int c;};   
+
+   main()
+   {
+      struct x z;
+     
+      z.a = 10;
+      z.b = 20;
+      z.c = 30;
+   }
+   
+
        +
        +
        +

        +And to retrieve a value from a structure member: +

        +

        + + +
        +
        +
+   struct x
+   {
+      int a;
+      int b;
+      int c;
+   };
+
+   main()
+   {
+      struct x z;
+	
+      z.a = 10;
+      z.a++;
+
+      printf(" first member is %d \n", z.a);   
+   }
+   
+
        +
        +
        +

        + +

        +

        Pointers to structures

        + +        Fast path to an explanation of the -> operator. +

        + +All that we have discussed so far has been OK but runs into problems +when structures have to be moved between functions for the following +reasons. +

          +
        • If the structure is large it is more effiecent to pass a +pointer to the structure +instead of the structure its self. This technic is also used to pass +pointers to arrays between +functions. +

          +

        • When passing a structure to a function, you actually pass a COPY of the +structure. Therefore it is not possible to change the values of members +within the structure as the copy is destroyed when the function ends. +
        +

        +So how does it all work? Here is an example. (make your browser W-I-D-E so +you can see the two examples). +

        +

        + + +
        +
        +					|
+					|
+   struct x {int a; int b; int c;} ;	| struct x {int a; int b; int c;} ;
+					|
+   void function(struct x);		| void function(struct x *);
+					|
+   main()			       	| main()
+   {					| {
+     struct x z;                        |   struct x z, *pz;	     /* 3 */
+					|   pz = &z;		     /* 4 */
+     z.a = 10;		/* 1 */		|   z.a = 10;
+     z.a++;				|   z.a++;
+					|
+     function(z);	/* 2 */	        | function(pz);		     /* 5 */
+   }					| }
+					|
+   void function( struct x z)		| void function(struct x * pz)
+   {					| {			     /* 6 */
+     printf(" first member %d \n", z.a);|   printf(" first member %d \n", (*pz).a);   
+   }					| }
+					|
+
        +
        +
        +

        +Here is the annotation. +

          +
        1. Give a structure member a value. +
        2. Pass a COPY of the whole structure to the function. +
        3. Define 'pz' a pointer to a structure of type 'x'. +
        4. Put the address of 'z' into 'pz'. 'pz' now POINTS to 'z'. +PLEASE NOTE. 'z' is defined to reserve memory equal to the size of the +structure. 'pz' only holds an address so will be 4 bytes long. +
        5. Pass the pointer into the function. +
        6. Print the value of the member 'a'. +
        + + +The (*pz).a syntax is used a great deal in C and it was decided to create +a short hand for it. So: + +
        +	(*pz).a   ==  pz->a
+
        + +Here is the final picture. +
        +
+   /*************************************************************************/
+
+   struct x {int a; int b; int c;} ;	/* Declare the structure.	    */
+
+   void function(struct x * );		/* Declare the function.	    */
+
+   /*************************************************************************/
+
+   main() 
+   {  
+					/* Declare two variables.
+					 * z == type struct x
+					 * pz == a pointer to type struct x
+					 */
+     struct x z, *pz; 			
+
+     pz = &z;        			/* put the address of 'z' into 'pz' */
+     z.a = 10;				/* initialize z.a		    */
+     z.a++;				/* Increment z.a		    */
+
+					/* print the contents of 'z.a'
+					 * using the pointer 'pz'	    */
+   
+     printf(" first member before the function call %d \n", pz->a);
+
+					/* Call 'function' passing the 
+					 * pointer 'pz'			    */
+     function(pz);  			
+
+					/* Print the NEW value of 'z.a'
+					 * using three different notations  */
+     printf(" first member after the function call %d \n", pz->a);
+     printf(" first member after the function call %d \n", (*pz).a);
+     printf(" first member after the function call %d \n", z.a);
+
+   }
+
+   /*************************************************************************/
+   
+   void function(struct x * pz)
+   { 
+					/* Print the value of 'z.a' by
+					 * referencing the pointer 'pz'
+					 * which holds the address of 'z'   */
+     printf(" first member inside the function %d \n", pz->a);
+      
+					/* Increment the value of 'z.a'
+					 * this is the source location
+					 * in memory.			    */
+     pz->a++;
+     
+   }
+
+   /*************************************************************************/
+  
+

        + +         +

        +

        +

        The Bottom Draw

        + +Finally, here is a little feature that allows you to save a little +space. +

        +

        + + +
        +
        +
+  main()
+  {
+    struct Flags
+    {
+      unsigned int Online  :1;   
+      unsigned int Mounted :1;
+    }
+
+    struct Flags TapeInfo;
+
+    TapeInfo.Online  = 1;
+    TapeInfo.Mounted = 0;
+  }
+  
+
        +
        +
        +

        +The :1 tells the compiler that only 1 byte is +required for Online and Mounted. There are a few points to +note about this though. +

          +
        • You may expect the compiler to reserve 2 bytes for the structure, it +actually reserves one word (usually 4 bytes) as this is the smallest unit +that can be reserved, the remaining 2 bytes are unavailable. +This is still better than the 2 words that wold normally get reserved. +
        • You can put any number into the variable, if the number is too large +to fit, the high order bits are lost without warning. +
        • Only signed int, unsigned int, int support this syntax. +
        +
        + +

        Examples

        +

        + + +This is the most basic struct example I could think of. +
        + + + +Using structure elements, and passing them into a function. +
        + + + +Passing a whole structure to a function. This performs a copy of the +structure so the same rules apply as for int etc. +Pointers to structures can be passed but I have not got to them yet.... +
        + + + +Define and use an array of structures. +

        The 'switch' and 'case' keywords

        +
        +
        +

        + +The switch-case statement is a multi-way decision statement. Unlike the +multiple decision statement that can be created using +if-else, the switch +statement evaluates the conditional +expression and tests it against +numerous +constant +values. The branch corresponding to the value that the +expression matches is taken during execution. +

        +The value of the expressions in a switch-case statement must be an ordinal +type i.e. +integer, char, short, long, +etc. Float and double are not +allowed. +

        +The syntax is : +

        +

        + + + + +
        +
        +
+     switch( expression )
+     {
+        case constant-expression1:	statements1;
+        [case constant-expression2:	statements2;]    
+        [case constant-expression3:	statements3;]
+        [default : statements4;]
+     }
+
        +
        +
        +

        + +The case statements and the default statement can occur in any +order in +the switch statement. The default clause is an optional clause +that is +matched if none of the constants in the case statements can be matched. +

        +Consider the example shown below: +

        +

        + + + + +
        +
        +
+     switch( Grade )
+     {
+        case 'A' : printf( "Excellent" );
+        case 'B' : printf( "Good" );
+        case 'C' : printf( "OK" );
+        case 'D' : printf( "Mmmmm...." );
+        case 'F' : printf( "You must do better than this" );    
+        default  : printf( "What is your grade anyway?" );
+     }		
+
        +
        +
        +

        + +Here, if the Grade is 'A' then the output will be +

        +

        + + + + +
        +
        +     Excellent
+     Good
+     OK
+     Mmmmm....
+     You must do better than this    
+     What is your grade anyway?
+
        +
        +
        +

        + +This is because, in the 'C' switch statement, execution continues on into +the next case clause if it is not explicitly specified that the execution +should exit the switch statement. The correct statement would be: +

        +

        + + + + +
        +
        +
+     switch( Grade )
+     {
+        case 'A' : printf( "Excellent" );
+                   break;
+
+        case 'B' : printf( "Good" );
+	           break;
+
+	case 'C' : printf( "OK" );
+	           break;
+
+        case 'D' : printf( "Mmmmm...." );
+	           break;
+
+	case 'F' : printf( "You must do better than this" );    
+	           break;
+
+	default  : printf( "What is your grade anyway?" );
+                   break;
+	}		
+
        +
        +
        +

        + +Although the break in the default clause (or in general, after +the last +clause) is not necessary, it is good programming practice to put it in +anyway. +

        +An example where it is better to allow the execution to continue into the +next case statement: +

        +

        + + + + +
        +
        +
+     char Ch;
+     .
+     .
+     switch( Ch )
+     {
+       			/* Handle lower-case characters */ 
+        case 'a' :
+        case 'b' :
+       	      .
+	      .
+	      .
+        case 'z' :
+          printf( "%c is a lower-case character.\n", Ch );
+	  printf( "Its upper-case is %c.\n" toupper(Ch) );      
+	  break;
+
+       			/* Handle upper-case characters */
+	case 'A' :	
+	case 'B' :
+	      .
+	      .
+	      .
+	case 'Z' :
+           printf( "%c is a upper-case character.\n", Ch );
+	   printf( "Its lower-case is %c.\n" tolower(Ch) );
+	   break;
+
+       			/* Handle digits and special characters */   
+
+        default  :
+           printf( "%c is not in the alphabet.\n", Ch );
+	   break;
+
+     }
+     .
+     .

        The TYPEDEF keyword.

        +
        +

        +Every variable has a +data type. typedef is used to define +new data type names to make a program more readable to the programmer. +

        +For example: +

        + +
        +
        +
+				|
+	main()	                |   main()
+        {	                |   {
+  	    int money;          |       typedef int Pounds;
+            money = 2;          |       Pounds money = 2
+        }	                |   } 
+
        +
        +

        +These examples are EXACTLY the same to the compiler. But the right hand +example tells the programmer the type of money he is dealing with. +

        + +A common use for typedef is to define a boolean data type as below. + +
        +Note: Recent C++ compilers have introduced a boolean datatype. +

        + +

        + +
        +
        +
+	typedef enum {FALSE=0, TRUE} Boolean
+
+	main ()
+        {
+	    Boolean flag = TRUE;
+	}
+        
+
        +
        +

        + +And as a final example, how about creating a string datatype? +

        + +
        +
        +
+     typedef char *String;
+     
+     main()
+     {
+         String Text = "Thunderbird";
+       
+         printf("%s\n", Text);
+     }
+     
+
        +
        +

        + +The main use for typedef seems to be defining +structures. For example: +

        + +
        +
        +
+	typedef struct {int age; char *name} person;
+	person people;
+
+
        +
        +

        + +Take care to note that person is now a type specifier and NOT a +variable name. +

        +As a final note, you can create several data types in one hit. + +
        +
        +
+
+	typedef int Pounds, Shillings, Pennies, Dollars, Cents;  
+
+
        +
        +

        + +

        +

        +

        Examples:

        + +Here is a rather heavy example of typedef. +
        +
        +

        Notes:

        +I would expect to see 'typedef' in header files. + +

        +

        The UNION keyword.

        +
        + +The union keyword allows several +variables of different type and size to occupy the same storage location. +

        +The syntax to define a union is simular to the +struct keyword as shown below:

        + + +

        +	union union_def { int a; float b; char c;} ;
+
        + +and a variable declared with either of these statements: + +
        +	union union_def union_var;
+	union { int a; float b; char c;} union_var;
+
        + +If you wish to initalise a variable you can say: + +
        +	union { int a; float b; char c;} union_var=97;
+
        + +By default the first variable (a) is initalised. +

        + +To assign a value to a variable you can say: + +

        +	union_var.b=99.99;
+	union_var.a=34;
+	union_var.c='x';
+
        +It's important to note that the storage will only hold ONE value, +looking at the +three lines above, union_var.a overwrites union_var.b and +then union_var.c overwrites union_var.a

        + + + +I have yet to see more than one use for this keyword. +

        The VOLATILE keyword.

        +
        +I have had several sugestions on how to describe volatile, +If you have any input please mail me. +
          +
        • The volatile keyword acts as a +data type qualifier. +The qualifier alters the default why in which +the compiler handles the variable and does not attempt to optimize the +storage referenced by it. Martin Leslie +

          +

        • volatile means the storage is likely to change at anytime +and be changed but something outside the control of the user program. +This means that if you reference the variable, +the program should always check the physical address (ie a mapped input fifo), +and not use it in a cashed way.Stephen Hunt +

          +

        • Here is an example for the usage of the volatile keyword: +
          +	/* Base address of the data input latch */
+
+	volatile unsigned char *baseAddr;
+
+	/* read parts of output latch */
+
+	lsb    = *handle->baseAddr;
+	middle = *handle->baseAddr;
+	msb    = *handle->baseAddr;
+
          +Between reads the bytes are changed in the latch. +

          +Without the volatile, the compiler optimises this to a single assignment: +

          +	lsb = middle = msb = *handle->baseAddr;
+
          +Tim Potter +

          +

        • A volatile variable is for dynamic use. E.G. for data that is to +be passed to an I/O port Here is an example. + +
          +	#define TTYPORT 0x17755U
+
+	volatile char *port17 = (char)*TTYPORT;
+	*port17 = 'o';
+	*port17 = 'N';
+
          +Without the volatile modifier, the compiler would think that the +statement *port17 = 'o'; is redundant and would remove it +from the object code. The volatile statement prevents the compiler +optimisation.Alex Arzon. +
        + +

        +

        The WHILE keyword.

        +
        +The while keyword is related to do +and for. Its purpose is to repeatedly execute +a block of statements. Here is +an example : + +

        +

        + + + + +
        +
        +
+        main()
+        {
+            int i=5;
+
+            while(--i)
+            {
+                printf(" i is %d\n", i);
+            }
+        }
+
        +
        +
        +

        + +The expression i-- is evaluated and if its +true the statements in the +block are executed. +The loop continues until the expression is false (zero). +The result will look like this: + +

        +

        + + + + +
        +
        +                
+                i is 4
+                i is 3
+                i is 2
+                i is 1
+
        +
        +
        +

        + +It is important to note that the statements +on a while will not get executed if the first evaluation of the +expression is FALSE. If you do not want this to happen you may prefer +to use the do statement. + +

        +

        +Now consider the next example. + +

        +

        + + + + +
        +
        +
+        main()
+        {
+            int i=5;
+
+            while(--i);
+            {
+                printf(" i is %d\n", i);
+            }
+        }
+
        +
        +
        + + +The result will look like this: + + +

        +

        + + + + +
        +
        +
+                i is 0
+
        +
        +
        + +

        +This is because of the ; on the end of the while +statement which means the while will loop (executing NULL statements) +until i is zero. Execution will then continue down the program +(to the printf). +

        + +

        +

        + +o +Basic while. +

        Iteration vs Recursion

        +
        + + +Most problems that can be solved with iteration ( +for, +while, +do +loops) can +also be solved with recursion. Pros and cons are: +
          +
        • Iteration code will be faster and will use less resources. +
        • Recursion normaly looks more like the original formula. +
        +Anyway up, as an example of both technics here is some code to give the +factorial of a number. +Iteration------ +Recursion +

        This document is an attempt at producing a reference guide for the +C programming language. To date, I have found several C tutorials and lessons +on the net but no reference documents. This is not an attempt to replace +the many high quality books available, but does try to provide an on-line +reference that can give answers to questions quickly and without hasle. +

        As usual, here is a disclaimer. +

        + + + +
        Every effort has been made to ensure all information and examples +are correct BUT no guarantee is implied or intended.

        Threads. +
        A process has five fundamental parts: code ("text"), data (VM), +stack, file I/O, and signal tables. Theads are spawned from a process +and can share these parts to comunicate with each other. +

        +The traditional method of spawning processes (fork) could only communicate +with other forked processes via pipes and and "shared memory". The result is +threads can communicate easily and have a low CPU overhead. +

        + +

        Variable. +
        An identifier (and storage) for a +data type +and for which the data value +is allowed to change as the program runs.

        C++ casting.

        +
        +

        + +C++ has added a new feature to +cast +that allows you to cast variables by using a slightly +more familuar syntax. Have a look at the example below. + +

        +

        + + + + +
        +
        +        
+    main()
+    {
+        int var1;
+        float var2;
+
+        var2 = float(var1);
+    }
+
        +
        +
        +

        +The example shows that casting can now look like a function call. +

        Function Overloading.

        +
        +

        +Overloading is a technique that allows you to give a several +functions with the same name but different parameter lists. +

        +Consider the following program. +

        +

        + + + + +
        +
        +
+    #include <iostream.h>
+    
+    void Add(int Left,   int Right);
+
+    main ()
+    {
+        Add(5, 9);              // Integer Add.
+        Add(3.2, 7.1);          // Floating point Add.
+    }
+ 
+    // Integer version of Add.
+       
+    void Add(int Left, int Right)
+    {
+        cout << Left << " + " << Right << " = " << Left+Right << endl;
+    }
+
        +
        +
        +

        +The program contains the Add function that adds integers. +But the main calls it twice, once passing integers and the second +time passing floating point numbers. The program will compile and run +but you will get incorrect results because the floats will be + cast to integers. +

        +The second +program offers a solution by overloading the Add function. + +

        +

        + + + + +
        +
        +
+    #include <iostream.h>
+    
+    void Add(int    Left, int    Right);
+    void Add(double Left, double Right);
+
+    main ()
+    {
+        Add(5, 9);             // Integer Add.        
+        Add(3.2, 7.1);         // Floating point Add. 
+    }
+ 
+    // Integer version of Add.
+       
+    void Add(int Left, int Right)
+    {
+        cout << Left << " + " << Right << " = " << Left+Right << endl;
+    }
+ 
+    // float version of Add.
+    
+    void Add(double Left, double Right)
+    {
+        cout << Left << " + " << Right << " = " << Left+Right << endl;
+    }
+
+
        +
        +
        + +The compiler can now look at the call list and match it with +a function with the correct parameter list and the floating +point addition is performed correctly. + +

        + +Please note that the returned argument is not used when matching +overloaded functions. + + +

        +

        Default Parameters.

        +
        +

        +Within C you could not provide default values for function +parameters. Well, C++ has come to your rescue. +

        + +

        + + + + +
        +
        +
+    #include <iostream.h>
+    
+    void Func( int one, int two=2, int three=3);
+    
+    main ()
+    {
+        Func(10, 20, 30);
+        Func(10, 20);   // Let the last parm default
+        Func(10);       // Just provide the required parm.
+    }
+    
+
+    void Func( int one, int two, int three)
+    {
+        cout << "One   = " << one   << endl;
+        cout << "Two   = " << two   << endl;
+        cout << "Three = " << three << endl << endl;
+    }
+
        +
        +
        + +

        +From this example, you can see that the prototype/function declaration +gives default values for the second and third parameters. It is now +down to the programmer calling the function to decide how many +s/he wants to provide. +

        +There are some basic rules that should be applied when using +default parameter values. +

          +
        • When a default is provided, all remaining parameters must be + given defaults. There can not be any holes. +
        • Default values must be of the correct type. +
        • Defaults can be placed on the function prototype or the function + definition. They can also be placed in both locations at the + same time. I have been told its good practice to place them + in the prototype only. +

        Inheritance.

        +
        +

        +Inheritance enables classes to use the properties of other classes and +add to those properties. +

        +The thing to remember about object programming is that it attempts to +create a software model as close to the real world as possible. Inheritance +forms an important role to meet this need. Take the following example. +

        +A fabric can have a colour and size and it is also used to make clothes +as well as tents. Now looking at this from the other angle tents are made +from fabric and poles but clothes are made from fabric and buttons. +So, Tents and clothes have something in common, fabric! If we described +tents and clothes in C++, we can seperate fabric into a seperate class +that the Tent and Clothes classes can inherit. +

        +

        + + + + +
        +
        +
+       -----------         
+      |  Fabric   |        
+       -----------         
+          A    A           
+          |    |           
+       ---      ---        
+      |            |       
+ ---------     ----------- 
+|  Tent   |   |  Clothes  |
+ ---------     ----------- 
+
+
+
        +
        +
        +

        +Now for some buzz words: +

          +
        1. Fabric is a base class +
        2. Tent and Clothes are derived classes +
        +This is what the code looks like: +

        +

        + + + + + +
        +
        +
+// ... The base class 'Fabric'
+// ... is no different to normal.
+
        +
        +
        +
+  class Fabric
+  {
+  public:
+
+       Fabric() {};
+      ~Fabric() {};
+
+      SetSize(int x, int y)
+      {
+          Length = x;
+          Width  = y;
+      };
+
+      SetColour(char *C)
+      {
+         strcpy(Colour, C); 
+      }
+
+  private:
+      int  Length;
+      int  Width;
+      char Colour[20];
+  };
+
+
        +
        +
        +

+
        +
        +
        +

        + +What we now have are three classes with the following public methods. + +

          +
        • Fabric +
            +
          1. SetSize +
          2. SetColour +
          +
        • Tents +
            +
          1. SetSize +
          2. SetColour +
          3. SetNumOfPoles +
          +
        • Clothes +
            +
          1. SetSize +
          2. SetColour +
          3. SetNumOfButtons +
          +
        + + +

        Using the classes

        + +So we have three classes, they are used in the same way as before but +with one extra feature. +

        +Consider this piece of code. + + +

        + + + + +
        +
        +  void Init(Fabric &Material);
+
+  main()
+  {
+      Tent       Frame;
+      Clothes    Jacket;
+
+      Init(Frame);
+      Init(Jacket);
+  }
+
+  void Init(Fabric &Material)
+  {
+      Material.SetColour("Red");
+      Material.SetSize  (10, 20);
+  }
+     
+
        +
        +
        +

        + +The function 'Init' expects an object of type 'Fabric' but we +are passing objects of type 'Tents' and 'Clothes', this is OK as +'Tents' and 'Clothes' are derived from Fabric. + +

        +

        +

        C++ Local Variables.

        +
        +

        + +There is not much difference between + C local variables but there +is one important feature that should be noted. +

          +
        • Variable definitions are now considered to be executable statements. +
        +This means that you can now put variable definitions anywhere in the code +and not jut at the start of a +block. +Here is an example. + +

        +

        + + +
        +
        +
+    main()
+    {
+        float pi = 3.142;   // Usual location for variable definitions
+        
+        cout << "PI is " << pi << endl;
+        
+        int Count = 1;      // C++ allows us to place a definition here.
+        
+        while (Count < 10)
+        {
+            cout << Count << endl;
+        }
+    }
+
        +
        +
        +

        + +It should be noted that Count is only in scope (usable) from the +point of definition and to the end of the block. +It can not be used in the previous cout statement. +

        + +The idea of this feature is to allow you to put variable declarations +near to the place +you wish to use them. Personnaly, I feel this should not be neccasary +if you write small concise functions.... + +There is one natty feature of this facility though. Check this +example out. +

        +

        + + +
        +
        +
+    main()
+    {
+        int Last = 10;      
+        
+        while (int Count; Count < Last; Count++)
+        {
+            cout << Count << endl;
+        }
+    }
+
        +
        +
        +

        +In this example, Count is defined inside the for +statement and only exists while the for block is being executed. + + +

        +

        +

        Reference Variables.

        +
        +

        +Reference variables allow two variable names to address the +same memory location. The following example shows the +technique in its simplest form. + +

        +

        + + + + +
        +
        +        
+    #include 
+    
+    main()
+    {
+        int var1;
+        int &var2 = var1;       // var2 is a reference variable.
+
+        var1 = 10;
+    
+        cout << "var1 = " << var1 << endl;
+        cout << "var2 = " << var2 << endl;
+    }
+
        +
        +
        +

        + + +Generally, you would not use a reference variable +in this way. Its more likely that they would be used +in function parameter lists to make the passing of +pointers more readable. +

        +This gives C++ the ability to provide a +different approch to changing a variable from within a +function. Consider the two following programs. + +

        +

        + + + + + + +
        +
        +
+    #include <stdio.h>
+
+    void Square(int *pVal);
+
+    main()
+    {
+        int Number=10;
+
+        printf("Number is %d\n", Number);
+
+        Square(&Number);
+
+        printf("Number is %d\n", Number);
+    }
+
+    void Square(int *pVal)
+    {
+        *pVal *= *pVal;            
+        
+        printf("Number is %d\n", *pVal);
+    }
+
+
        +        		 +
        +
+    #include <stdio.h>
+
+    void Square(int &Val);
+
+    main()
+    {
+        int Number=10;
+
+        printf("Number is %d\n", Number);
+
+        Square(Number);
+
+        printf("Number is %d\n", Number);
+    }
+
+    void Square(int &Val)
+    {
+        Val *= Val;
+        
+        printf("Number is %d\n", Val);
+    }
+
+
        +
        +
        +

        + +The program on the right should be clearer to read +because you do not need to worry about pointer +dereferencing. + +

        GNU LIBRARY GENERAL PUBLIC LICENSE

        +Version 2, June 1991 +

        +

        +Copyright (C) 1991 Free Software Foundation, Inc.
+675 Mass Ave, Cambridge, MA 02139, USA
+Everyone is permitted to copy and distribute verbatim copies
+of this license document, but changing it is not allowed.
+
+[This is the first released version of the library GPL.  It is
+ numbered 2 because it goes with version 2 of the ordinary GPL.]
+
        +

        +

        Preamble

        +

        + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +Licenses are intended to guarantee your freedom to share and change +free software--to make sure the software is free for all its users. +

        + This license, the Library General Public License, applies to some +specially designated Free Software Foundation software, and to any +other libraries whose authors decide to use it. You can use it for +your libraries, too. +

        + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. +

        + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if +you distribute copies of the library, or if you modify it. +

        + For example, if you distribute copies of the library, whether gratis +or for a fee, you must give the recipients all the rights that we gave +you. You must make sure that they, too, receive or can get the source +code. If you link a program with the library, you must provide +complete object files to the recipients so that they can relink them +with the library, after making changes to the library and recompiling +it. And you must show them these terms so they know their rights. +

        + Our method of protecting your rights has two steps: (1) copyright +the library, and (2) offer you this license which gives you legal +permission to copy, distribute and/or modify the library. +

        + Also, for each distributor's protection, we want to make certain +that everyone understands that there is no warranty for this free +library. If the library is modified by someone else and passed on, we +want its recipients to know that what they have is not the original +version, so that any problems introduced by others will not reflect on +the original authors' reputations. +

        + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that companies distributing free +software will individually obtain patent licenses, thus in effect +transforming the program into proprietary software. To prevent this, +we have made it clear that any patent must be licensed for everyone's +free use or not licensed at all. +

        + Most GNU software, including some libraries, is covered by the ordinary +GNU General Public License, which was designed for utility programs. This +license, the GNU Library General Public License, applies to certain +designated libraries. This license is quite different from the ordinary +one; be sure to read it in full, and don't assume that anything in it is +the same as in the ordinary license. +

        + The reason we have a separate public license for some libraries is that +they blur the distinction we usually make between modifying or adding to a +program and simply using it. Linking a program with a library, without +changing the library, is in some sense simply using the library, and is +analogous to running a utility program or application program. However, in +a textual and legal sense, the linked executable is a combined work, a +derivative of the original library, and the ordinary General Public License +treats it as such. +

        + Because of this blurred distinction, using the ordinary General +Public License for libraries did not effectively promote software +sharing, because most developers did not use the libraries. We +concluded that weaker conditions might promote sharing better. +

        + However, unrestricted linking of non-free programs would deprive the +users of those programs of all benefit from the free status of the +libraries themselves. This Library General Public License is intended to +permit developers of non-free programs to use free libraries, while +preserving your freedom as a user of such programs to change the free +libraries that are incorporated in them. (We have not seen how to achieve +this as regards changes in header files, but we have achieved it as regards +changes in the actual functions of the Library.) The hope is that this +will lead to faster development of free libraries. +

        + The precise terms and conditions for copying, distribution and +modification follow. Pay close attention to the difference between a +"work based on the library" and a "work that uses the library". The +former contains code derived from the library, while the latter only +works together with the library. +

        + Note that it is possible for a library to be covered by the ordinary +General Public License rather than by this special one. +

        +

        TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

        +

        +

          +
        1. +This License Agreement applies to any software library which +contains a notice placed by the copyright holder or other authorized +party saying it may be distributed under the terms of this Library +General Public License (also called "this License"). Each licensee is +addressed as "you". +

          + A "library" means a collection of software functions and/or data +prepared so as to be conveniently linked with application programs +(which use some of those functions and data) to form executables. +

          + The "Library", below, refers to any such software library or work +which has been distributed under these terms. A "work based on the +Library" means either the Library or any derivative work under +copyright law: that is to say, a work containing the Library or a +portion of it, either verbatim or with modifications and/or translated +straightforwardly into another language. (Hereinafter, translation is +included without limitation in the term "modification".) +

          + "Source code" for a work means the preferred form of the work for +making modifications to it. For a library, complete source code means +all the source code for all modules it contains, plus any associated +interface definition files, plus the scripts used to control compilation +and installation of the library. +

          + Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running a program using the Library is not restricted, and output from +such a program is covered only if its contents constitute a work based +on the Library (independent of the use of the Library in a tool for +writing it). Whether that is true depends on what the Library does +and what the program that uses the Library does. + +

        2. +You may copy and distribute verbatim copies of the Library's +complete source code as you receive it, in any medium, provided that +you conspicuously and appropriately publish on each copy an +appropriate copyright notice and disclaimer of warranty; keep intact +all the notices that refer to this License and to the absence of any +warranty; and distribute a copy of this License along with the +Library. +

          + You may charge a fee for the physical act of transferring a copy, +and you may at your option offer warranty protection in exchange for a +fee. +

          +

        3. +You may modify your copy or copies of the Library or any portion +of it, thus forming a work based on the Library, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: +

          +

            +
          1. +The modified work must itself be a software library. +

            +

          2. +You must cause the files modified to carry prominent notices +stating that you changed the files and the date of any change. +

            +

          3. +You must cause the whole of the work to be licensed at no +charge to all third parties under the terms of this License. +

            +

          4. +If a facility in the modified Library refers to a function or a +table of data to be supplied by an application program that uses +the facility, other than as an argument passed when the facility +is invoked, then you must make a good faith effort to ensure that, +in the event an application does not supply such function or +table, the facility still operates, and performs whatever part of +its purpose remains meaningful. +

            +(For example, a function in a library to compute square roots has +a purpose that is entirely well-defined independent of the +application. Therefore, Subsection 2d requires that any +application-supplied function or table used by this function must +be optional: if the application does not supply it, the square +root function must still compute square roots.) +

          +

          +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Library, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Library, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote +it. +

          +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Library. +

          +In addition, mere aggregation of another work not based on the Library +with the Library (or with a work based on the Library) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. +

          +

        4. +You may opt to apply the terms of the ordinary GNU General Public +License instead of this License to a given copy of the Library. To do +this, you must alter all the notices that refer to this License, so +that they refer to the ordinary GNU General Public License, version 2, +instead of to this License. (If a newer version than version 2 of the +ordinary GNU General Public License has appeared, then you can specify +that version instead if you wish.) Do not make any other change in +these notices. +

          + Once this change is made in a given copy, it is irreversible for +that copy, so the ordinary GNU General Public License applies to all +subsequent copies and derivative works made from that copy. +

          + This option is useful when you wish to copy part of the code of +the Library into a program that is not a library. +

          +

        5. +You may copy and distribute the Library (or a portion or +derivative of it, under Section 2) in object code or executable form +under the terms of Sections 1 and 2 above provided that you accompany +it with the complete corresponding machine-readable source code, which +must be distributed under the terms of Sections 1 and 2 above on a +medium customarily used for software interchange. +

          + If distribution of object code is made by offering access to copy +from a designated place, then offering equivalent access to copy the +source code from the same place satisfies the requirement to +distribute the source code, even though third parties are not +compelled to copy the source along with the object code. +

          +

        6. +A program that contains no derivative of any portion of the +Library, but is designed to work with the Library by being compiled or +linked with it, is called a "work that uses the Library". Such a +work, in isolation, is not a derivative work of the Library, and +therefore falls outside the scope of this License. +

          + However, linking a "work that uses the Library" with the Library +creates an executable that is a derivative of the Library (because it +contains portions of the Library), rather than a "work that uses the +library". The executable is therefore covered by this License. +Section 6 states terms for distribution of such executables. +

          + When a "work that uses the Library" uses material from a header file +that is part of the Library, the object code for the work may be a +derivative work of the Library even though the source code is not. +Whether this is true is especially significant if the work can be +linked without the Library, or if the work is itself a library. The +threshold for this to be true is not precisely defined by law. +

          + If such an object file uses only numerical parameters, data +structure layouts and accessors, and small macros and small inline +functions (ten lines or less in length), then the use of the object +file is unrestricted, regardless of whether it is legally a derivative +work. (Executables containing this object code plus portions of the +Library will still fall under Section 6.) +

          + Otherwise, if the work is a derivative of the Library, you may +distribute the object code for the work under the terms of Section 6. +Any executables containing that work also fall under Section 6, +whether or not they are linked directly with the Library itself. +

          +

        7. +As an exception to the Sections above, you may also compile or +link a "work that uses the Library" with the Library to produce a +work containing portions of the Library, and distribute that work +under terms of your choice, provided that the terms permit +modification of the work for the customer's own use and reverse +engineering for debugging such modifications. +

          + You must give prominent notice with each copy of the work that the +Library is used in it and that the Library and its use are covered by +this License. You must supply a copy of this License. If the work +during execution displays copyright notices, you must include the +copyright notice for the Library among them, as well as a reference +directing the user to the copy of this License. Also, you must do one +of these things: +

          +

            +
          1. +Accompany the work with the complete corresponding +machine-readable source code for the Library including whatever +changes were used in the work (which must be distributed under +Sections 1 and 2 above); and, if the work is an executable linked +with the Library, with the complete machine-readable "work that +uses the Library", as object code and/or source code, so that the +user can modify the Library and then relink to produce a modified +executable containing the modified Library. (It is understood +that the user who changes the contents of definitions files in the +Library will not necessarily be able to recompile the application +to use the modified definitions.) +

            +

          2. +Accompany the work with a written offer, valid for at +least three years, to give the same user the materials +specified in Subsection 6a, above, for a charge no more +than the cost of performing this distribution. +

            +

          3. +If distribution of the work is made by offering access to copy +from a designated place, offer equivalent access to copy the above +specified materials from the same place. +

            +

          4. +Verify that the user has already received a copy of these +materials or that you have already sent this user a copy. +
          +

          + For an executable, the required form of the "work that uses the +Library" must include any data and utility programs needed for +reproducing the executable from it. However, as a special exception, +the source code distributed need not include anything that is normally +distributed (in either source or binary form) with the major +components (compiler, kernel, and so on) of the operating system on +which the executable runs, unless that component itself accompanies +the executable. +

          + It may happen that this requirement contradicts the license +restrictions of other proprietary libraries that do not normally +accompany the operating system. Such a contradiction means you cannot +use both them and the Library together in an executable that you +distribute. +

          +

        8. +You may place library facilities that are a work based on the +Library side-by-side in a single library together with other library +facilities not covered by this License, and distribute such a combined +library, provided that the separate distribution of the work based on +the Library and of the other library facilities is otherwise +permitted, and provided that you do these two things: +

          +

            +
          1. +Accompany the combined library with a copy of the same work +based on the Library, uncombined with any other library +facilities. This must be distributed under the terms of the +Sections above. +

            +

          2. +Give prominent notice with the combined library of the fact +that part of it is a work based on the Library, and explaining +where to find the accompanying uncombined form of the same work. +
          +

          +

        9. +You may not copy, modify, sublicense, link with, or distribute +the Library except as expressly provided under this License. Any +attempt otherwise to copy, modify, sublicense, link with, or +distribute the Library is void, and will automatically terminate your +rights under this License. However, parties who have received copies, +or rights, from you under this License will not have their licenses +terminated so long as such parties remain in full compliance. +

          +

        10. +You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Library or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Library (or any work based on the +Library), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Library or works based on it. +

          +

        11. +Each time you redistribute the Library (or any work based on the +Library), the recipient automatically receives a license from the +original licensor to copy, distribute, link with or modify the Library +subject to these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. +

          +

        12. +If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Library at all. For example, if a patent +license would not permit royalty-free redistribution of the Library by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Library. +

          +If any portion of this section is held invalid or unenforceable under any +particular circumstance, the balance of the section is intended to apply, +and the section as a whole is intended to apply in other circumstances. +

          +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. +

          +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. +

          +

        13. +If the distribution and/or use of the Library is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Library under this License may add +an explicit geographical distribution limitation excluding those countries, +so that distribution is permitted only in or among countries not thus +excluded. In such case, this License incorporates the limitation as if +written in the body of this License. +

          +

        14. +The Free Software Foundation may publish revised and/or new +versions of the Library General Public License from time to time. +Such new versions will be similar in spirit to the present version, +but may differ in detail to address new problems or concerns. +

          +Each version is given a distinguishing version number. If the Library +specifies a version number of this License which applies to it and +"any later version", you have the option of following the terms and +conditions either of that version or of any later version published by +the Free Software Foundation. If the Library does not specify a +license version number, you may choose any version ever published by +the Free Software Foundation. +

          +

        15. +If you wish to incorporate parts of the Library into other free +programs whose distribution conditions are incompatible with these, +write to the author to ask for permission. For software which is +copyrighted by the Free Software Foundation, write to the Free +Software Foundation; we sometimes make exceptions for this. Our +decision will be guided by the two goals of preserving the free status +of all derivatives of our free software and of promoting the sharing +and reuse of software generally. +

          +

          NO WARRANTY

          +

          +

        16. +BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO +WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. +EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR +OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY +KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE +IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE +LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME +THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. +

          +

        17. +IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN +WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY +AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU +FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR +CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE +LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING +RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A +FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF +SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH +DAMAGES. +
        +

        +

        END OF TERMS AND CONDITIONS

        +

        +

        How to Apply These Terms to Your New Libraries

        +

        + If you develop a new library, and you want it to be of the greatest +possible use to the public, we recommend making it free software that +everyone can redistribute and change. You can do so by permitting +redistribution under these terms (or, alternatively, under the terms of the +ordinary General Public License). +

        + To apply these terms, attach the following notices to the library. It is +safest to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least the +"copyright" line and a pointer to where the full notice is found. +

        +

        +one line to give the library's name and an idea of what it does.

        Trouble in Installation

        +

        +Here are some of the things that have caused trouble for people installing +GNU C++ library. +

        +

          +
        1. +Make sure that your GNU C++ version number is at least as high as your +libg++ version number. For example, libg++ 1.22.0 requires g++ 1.22.0 or +later releases. +

          +

        2. +Double-check system constants in the header files mentioned above. +

          +

        +

        +

        GNU C++ library aims, objectives, and limitations

        +

        +The GNU C++ library, libg++ is an attempt to provide a variety of C++ +programming tools and other support to GNU C++ programmers. +

        +Differences in distribution policy are only part of the difference +between libg++.a and AT&T libC.a. libg++ is not intended to be an +exact clone of libC. For one, libg++ contains bits of code that depend +on special features of GNU g++ that are either different or lacking in +the AT&T version, including slightly different inlining and overloading +strategies, dynamic local arrays, etc. All of these +differences are minor. For example, while the AT&T and GNU stream +classes are implemented in very different ways, the vast majority of +C++ programs compile and run under either version with no visible +difference. Additionally, all g++-specific constructs are conditionally +compiled; The library is designed to be compatible with any 2.0 C++ +compiler. +

        +libg++ has also contained workarounds for some limitations in g++: both +g++ and libg++ are still undergoing rapid development and testing--a +task that is helped tremendously by the feedback of active users. This +manual is also still under development; it has some catching up to do +to include all the facilities now in the library. +

        +libg++ is not the only freely available source of C++ class libraries. +Some notable alternative sources are Interviews and NIHCL. +(InterViews has been available on the X-windows X11 tapes and also +from interviews.stanford.edu. NIHCL is available by anonymous +ftp from GNU archives (such as the pub directory of prep.ai.mit.edu), +although it is not supported by the FSF - and needs some work +before it will work with g++.) +

        +As every C++ programmer knows, the design (moreso than the +implementation) of a C++ class library is something of a challenge. +Part of the reason is that C++ supports two, partially incompatible, +styles of object-oriented programming -- The "forest" approach, +involving a collection of free-standing classes that can be mixed and +matched, versus the completely hierarchical (smalltalk style) +approach, in which all classes are derived from a common ancestor. Of +course, both styles have advantages and disadvantages. So far, libg++ +has adopted the "forest" approach. Keith Gorlen's OOPS library adopts +the hierarchical approach, and may be an attractive alternative for C++ +programmers who prefer this style. +

        +Currently (and/or in the near future) libg++ provides support for a +few basic kinds of classes: +

        +The first kind of support provides an interface between C++ programs and +C libraries. This includes basic header files (like `stdio.h') as +well as things like the File and stream classes. Other classes that +interface to other aspects of C libraries (like those that maintain +environmental information) are in various stages of development; all +will undergo implementation modifications when the forthcoming GNU libc +library is released. +

        +The second kind of support contains general-purpose basic classes that +transparently manage variable-sized objects on the freestore. This +includes Obstacks, multiple-precision Integers and Rationals, +arbitrary length Strings, BitSets, and BitStrings. +

        +Third, several classes and utilities of common interest (e.g., +Complex numbers) are provided. +

        +Fourth, a set of pseudo-generic prototype files are available +as a mechanism for generating common container classes. These +are described in more detail in the introduction to container +prototypes. Currently, only a textual substitution +mechanism is available for generic class creation. +

        +

        GNU C++ library stylistic conventions

        +

        +

          +

          +

        • +C++ source files have file extension `.cc'. Both C-compatibility +header files and class declaration files have extension `.h'. +

          +

        • +C++ class names begin with capital letters, except for istream +and ostream, for AT&T C++ compatibility. Multi-word class +names capitalize each word, with no underscore separation. +

          +

        • +Include files that define C++ classes begin with capital letters +(as do the names of the classes themselves). `stream.h' is +uncapitalized for AT&T C++ compatibility. +

          +

        • +Include files that supply function prototypes for other C +functions (system calls and libraries) are all lower case. +

          +

        • +All include files define a preprocessor variable _X_h, where X +is the name of the file, and conditionally compile only if this +has not been already defined. The #pragma once facility +is also used to avoid re-inclusion. +

          +

        • +Structures and objects that must be publicly defined, +but are not intended for public use have names beginning +with an underscore. (for example, the _Srep struct, which +is used only by the String and SubString classes.) +

          +

        • +The underscore is used to separate components of long function +names,
          e.g., set_File_exception_handler(). +

          +

        • +When a function could be usefully defined either as a +member or a friend, it is generally a member if it modifies +and/or returns itself, else it is a friend. There are cases +where naturalness of expression wins out over this rule. +

          +

        • +Class declaration files are formatted so that it is easy +to quickly check them to determine function names, parameters, +and so on. Because of the different kinds of things that may +appear in class declarations, there is no perfect way to do +this. Any suggestions on developing a common class +declaration formatting style are welcome. +

          +

        • +All classes use the same simple error (exception) handling strategy. +Almost every class has a member function named error(char* msg) +that invokes an associated error handler function via a pointer to that +function, so that the error handling function may be reset by +programmers. By default nearly all call *lib_error_handler, which +prints the message and then aborts execution. This system is subject +to change. In general, errors are assumed to be non-recoverable: +Library classes do not include code that allows graceful continuation +after exceptions. +

          +

        +

        +

        Support for representation invariants

        +

        +Most GNU C++ library classes possess a method named OK(), +that is useful in helping to verify correct performance of class +operations. +

        +The OK() operations checks the "representation invariant" of a +class object. This is a test to check whether the object is in a valid +state. In effect, it is a (sometimes partial) verification of the +library's promise that (1) class operations always leave objects in +valid states, and (2) the class protects itself so that client functions +cannot corrupt this state. +

        +While no simple validation technique can assure that all operations +perform correctly, calls to OK() can at least verify that +operations do not corrupt representations. For example for String +a, b, c; ... a = b + c;, a call to a.OK(); will guarantee that +a is a valid String, but does not guarantee that it +contains the concatenation of b + c. However, given that a +is known to be valid, it is possible to further verify its properties, +for example via a.after(b) == c && a.before(c) == b. In other +words, OK() generally checks only those internal representation +properties that are otherwise inaccessible to users of the class. Other +class operations are often useful for further validation. +

        +Failed calls to OK() call a class's error method if +one exists, else directly call abort. Failure indicates +an implementation error that should be reported. +

        +With only rare exceptions, the internal support functions for a class +never themselves call OK() (although many of the test files +in the distribution call OK() extensively). +

        +Verification of representational invariants can sometimes be +very time consuming for complicated data structures. +

        +

        Introduction to container class prototypes

        +

        +As a temporary mechanism enabling the support of generic classes, the GNU +C++ Library distribution contains a directory (`g++-include') of files +designed to serve as the basis for generating container classes of +specified elements. These files can be used to generate `.h' and +`.cc' files in the current directory via a supplied shell script +program that performs simple textual substitution to create specific +classes. +

        +While these classes are generated independently, and thus share no code, +it is possible to create versions that do share code among subclasses. For +example, using typedef void* ent, and then generating a +entList class, other derived classes could be created using the +void* coercion method described in Stroustrup, pp204-210. +

        +This very simple class-generation facility is useful enough to serve +current purposes, but will be replaced with a more coherent mechanism for +handling C++ generics in a way that minimally disrupts current usage. +Without knowing exactly when or how parametric classes might be +added to the C++ language, provision of this simplest possible +mechanism, textual substitution, appears to be the safest strategy, +although it does require certain redundancies and awkward constructions. +

        +Specific classes may be generated via the `genclass' shell script +program. This program has arguments specifying the kinds of base types(s) +to be used. Specifying base types requires two arguments. The first is the +name of the base type, which may be any named type, like int or +String. Only named types are supported; things like int* are +not accepted. However, pointers like this may be used by supplying the +appropriate typedefs (e.g., editing the resulting files to include +typedef int* intp;). The type name must be followed by one of the +words val or ref, to indicate whether the base elements +should be passed to functions by-value or by-reference. +

        +You can specify basic container classes using genclass base +[val,ref] proto, where proto is the name of the class being +generated. Container classes like dictionaries and maps that require +two types may be specified via genclass -2 keytype [val, ref], +basetype [val, ref] proto, where the key type is specified first and +the contents type second. The resulting classnames and filenames are +generated by prepending the specified type names to the prototype names, +and separating the filename parts with dots. For example, +genclass int val List generates class intList residing in +files `int.List.h' and `int.List.cc'. genclass -2 String +ref int val VHMap generates (the awkward, but unavoidable) class name +StringintVHMap. Of course, programmers may use typedef or +simple editing to create more appropriate names. The existence of dot +seperators in file names allows the use of GNU make to help automate +configuration and recompilation. An example Makefile exploiting such +capabilities may be found in the `libg++/proto-kit' directory. +

        +The genclass utility operates via simple text substitution using +sed. All occurrences of the pseudo-types <T> and <C> +(if there are two types) are replaced with the indicated type, and +occurrences of <T&> and <C&> are replaced by just the types, +if val is specified, or types followed by "&" if ref is +specified. +

        +Programmers will frequently need to edit the `.h' file in order to +insert additional #include directives or other modifications. A +simple utility, `prepend-header' to prepend other `.h' files +to generated files is provided in the distribution. +

        +One dubious virtue of the prototyping mechanism is that, because sources files, +not archived library classes, are generated, it is relatively simple for +programmers to modify container classes in the common case where slight +variations of standard container classes are required. +

        +It is often a good idea for programmers to archive (via ar) +generated classes into `.a' files so that only those class +functions actually used in a given application will be loaded. +The test subdirectory of the distribution shows an example of this. +

        +Because of #pragma interface directives, the `.cc' files +should be compiled with -O or -DUSE_LIBGXX_INLINES +enabled. +

        +Many container classes require specifications over and above the base +class type. For example, classes that maintain some kind of ordering of +elements require specification of a comparison function upon which to +base the ordering. This is accomplished via a prototype file +`defs.hP' that contains macros for these functions. While these +macros default to perform reasonable actions, they can and should be +changed in particular cases. Most prototypes require only one or a few +of these. No harm is done if unused macros are defined to perform +nonsensical actions. The macros are: +

        +

        +

        +

        DEFAULT_INITIAL_CAPACITY +
        The initial capacity for containers (e.g., hash tables) that require +an initial capacity argument for constructors. +Default: 100 +

        +

        <T>EQ(a, b) +
        return true if a is considered equal to b for the purposes of +locating, etc., an element in a container. +Default: (a == b) +

        +

        <T>LE(a, b) +
        return true if a is less than or equal to b +Default: (a <= b) +

        +

        <T>CMP(a, b) +
        return an integer < 0 if a<b, 0 if a==b, or > 0 if a>b. +Default: (a <= b)? (a==b)? 0 : -1 : 1 +

        +

        <T>HASH(a) +
        return an unsigned integer representing the hash of a. +Default: hash(a) ; where extern unsigned int hash(<T&>). +(note: several useful hash functions are declared in builtin.h +and defined in hash.cc) +

        +

        +

        +Nearly all prototypes container classes support container +traversal via Pix pseudo indices, as described elsewhere. +

        +All object containers must perform either a X::X(X&) (or +X::X() followed by X::operator =(X&)) to copy objects into +containers. (The latter form is used for containers built from C++ +arrays, like VHSets). When containers are destroyed, they invoke +X::~X(). Any objects used in containers must have well behaved +constructors and destructors. If you want to create containers that +merely reference (point to) objects that reside elsewhere, and are not +copied or destroyed inside the container, you must use containers +of pointers, not containers of objects. +

        +All prototypes are designed to generate HOMOGENOUS container +classes. There is no universally applicable method in C++ to support +heterogenous object collections with elements of various subclasses of +some specified base class. The only way to get heterogenous structures +is to use collections of pointers-to-objects, not collections of objects +(which also requires you to take responsibility for managing storage for +the objects pointed to yourself). +

        +For example, the following usage illustrates a commonly encountered +danger in trying to use container classes for heterogenous structures: +

        +

        +class Base { int x; ...}
+class Derived : public Base { int y; ... }
+
+BaseVHSet s; // class BaseVHSet generated via something like
+             // `genclass Base ref VHSet'
+
+void f()
+{
+  Base b;
+  s.add(b); // OK
+
+  Derived d;
+  s.add(d);  // (CHOP!)
+}
+
        +

        +At the line flagged with `(CHOP!)', a Base::Base(Base&) is +called inside Set::add(Base&)---not +Derived::Derived(Derived&). Actually, in VHSet, a +Base::operator =(Base&), is used instead to place the element in +an array slot, but with the same effect. So only the Base part is +copied as a VHSet element (a so-called chopped-copy). In this +case, it has an x part, but no y part; and a Base, not +Derived, vtable. Objects formed via chopped copies are rarely +sensible.

        +To avoid this, you must resort to pointers: +

        +

        +typedef Base* BasePtr;
+
+BasePtrVHSet s; // class BaseVHSet generated via something like
+                // `genclass BasePtr val VHSet'
+
+void f()
+{
+  Base* bp = new Base;
+  s.add(b);
+
+  Base* dp = new Derived;
+  s.add(d);  // works fine.
+
+  // Don't forget to delete bp and dp sometime.
+  // The VHSet won't do this for you.
+}
+
        +

        +

        Example

        +

        +The prototypes can be difficult to use on first attempt. Here is an +example that may be helpful. The utilities in the `proto-kit' +simplify much of the actions described, but are not used here. +

        +Suppose you create a class Person, and want to make an Map that +links the social security numbers associated with each person. You start +off with a file `Person.h' +

        +

        +
+#include <String.h>
+
+class Person
+{
+  String nm;
+  String addr;
+  //...
+public:
+  const String& name() { return nm; }
+  const String& address() { return addr; }
+  void          print() { ... }
+  //...
+}
+
+
        +

        +And in file `SSN.h', +

        +

        +typedef unsigned int SSN;
+
        +

        +Your first decision is what storage/usage strategy to use. There are +several reasonable alternatives here: You might create an "object +collection" of Persons, a "pointer collection" of +pointers-to-Persons, or even a simple String map, housing either copies +of pointers to the names of Persons, since other fields are unused for +purposes of the Map. In an object collection, instances of class Person +"live" inside the Map, while in a pointer collection, the instances +live elsewhere. Also, as above, if instances of subclasses of Person are +to be used inside the Map, you must use pointers. In a String Map, the +same difference holds, but now only for the name fields. Any of these +choices might make sense in particular applications. +

        +The second choice is the Map implementation strategy. Either a tree +or a hash table might make sense. Suppose you want an AVL tree Map. +There are two things to now check. First, as an object collection, +the AVLMap requires that the elsement class contain an X(X&) +constructor. In C++, if you don't specify such a constructor, one +is constructed for you, but it is a very good idea to always do this +yourself, to avoid surprises. In this example, you'd use something like +

        +class Person 
+{ ...; 
+    Person(const Person& p) :nm(p.nm), addr(p.addr) {}
+};
+
        +

        +Also, an AVLMap requires a comparison function for elements in order +to maintain order. Rather than requiring you to write a particular +comparison function, a `defs' file is consulted to determine how to +compare items. You must create and edit such a file. +

        +Before creating `Person.defs.h', you must first make one additional +decision. Should the Map member functions like m.contains(p) +take arguments (p) by reference (i.e., typed as +int Map::contains(const Person& p) or by value (i.e., typed as +int Map::contains(const Person p). Generally, for user-defined +classes, you want to pass by reference, and for builtins and pointers, +to pass by value. SO you should pick by-reference. +

        +You can now create `Person.defs.h' via genclass Person ref defs. +This creates a simple skeleton that you must edit. First, add +#include "Person.h" to the top. Second, edit the <T>CMP(a,b) +macro to compare on name, via +

        +

        +#define <T>CMP(a, b) ( compare(a.name(), b.name()) )
+
        +

        +which invokes the int compare(const String&, const String&) +function from `String.h'. Of course, you could define this in any +other way as well. In fact, the default versions in the skeleton turn +out to be OK (albeit inefficient) in this particular example. +

        +You may also want to create file `SSN.defs.h'. Here, choosing +call-by-value makes sense, and since no other capabilities (like +comparison functions) of the SSNs are used (and the defaults are OK +anyway), you'd type +

        +

        +genclass SSN val defs
+
        +

        +and then edit to place #include "SSN.h" at the top. +

        +Finally, you can generate the classes. First, generate the base +class for Maps via +

        +

        +genclass -2 Person ref SSN val Map
+
        +

        +This generates only the abstract class, not the implementation, in file +`Person.SSN.Map.h' and `Person.SSN.Map.cc'. To create the +AVL implementation, type +

        +

        +genclass -2 Person ref SSN val AVLMap
+
        +

        +This creates the class PersonSSNAVLMap, in +`Person.SSN.AVLMap.h' and `Person.SSN.AVLMap.cc'. +

        +To use the AVL implementation, compile the two generated `.cc' files, and +specify `#include "Person.SSN.AVLMap.h"' in the application program. +All other files are included in the right ways automatically. +

        +One last consideration, peculiar to Maps, is to pick a reasonable +default contents when declaring an AVLMap. Zero might be appropriate +here, so you might declare a Map, +

        +

        +PersonSSNAVLMap m((SSN)0);
+
        +

        +Suppose you wanted a VHMap instead of an AVLMap Besides +generating different implementations, there are two differences in +how you should prepare the `defs' file. First, because a VHMap +uses a C++ array internally, and because C++ array slots are initialized +differently than single elements, you must ensure that class Person +contains (1) a no-argument constructor, and (2) an assignment operator. +You could arrange this via +

        +

        +class Person 
+{ ...; 
+    Person() {}
+  void operator = (const Person& p) { nm = p.nm; addr = p.addr; }
+};
+
        +

        +(The lack of action in the constructor is OK here because Strings +possess usable no-argument constructors.) +

        +You also need to edit `Person.defs.h' to indicate a usable hash +function and default capacity, via something like +

        +

        +#include <builtin.h>
+#define <T>HASH(x)  (hashpjw(x.name().chars()))
+#define DEFAULT_INITIAL_CAPACITY 1000
+
        +

        +Since the hashpjw function from `builtin.h' is +appropriate here. Changing the default capacity to a value +expected to exceed the actual capacity helps to avoid +"hidden" inefficiencies when a new VHMap is created without +overriding the default, which is all too easy to do. +

        +Otherwise, everything is the same as above, substituting +VHMap for AVLMap. +

        +

        Variable-Sized Object Representation

        +

        +One of the first goals of the GNU C++ library is to enrich the kinds of +basic classes that may be considered as (nearly) "built into" C++. A good +deal of the inspiration for these efforts is derived from considering +features of other type-rich languages, particularly Common Lisp and Scheme. +The general characteristics of most class and friend operators and +functions supported by these classes has been heavily influenced +by such languages. +

        +Four of these types, Strings, Integers, BitSets, and BitStrings (as well as +associated and/or derived classes) require representations suitable for +managing variable-sized objects on the free-store. The basic technique used +for all of these is the same, although various details necessarily differ +from class to class. +

        +The general strategy for representing such objects is to create chunks of +memory that include both header information (e.g., the size of the object), +as well as the variable-size data (an array of some sort) at the end +of the chunk. Generally the maximum size of an object is limited to +something less than all of addressable memory, as a safeguard. The minimum +size is also limited so as not to waste allocations expanding very small +chunks. Internally, chunks are allocated in blocks well-tuned to the +performance of the new operator. +

        +Class elements themselves are merely pointers to these chunks. +Most class operations are performed via inline "translation" +functions that perform the required operation on the corresponding +representation. However, constructors and assignments operate by +copying entire representations, not just pointers. +

        +No attempt is made to control temporary creation in expressions +and functions involving these classes. Users of previous versions +of the classes will note the disappearance of both "Tmp" classes +and reference counting. These were dropped because, while they +did improve performance in some cases, they obscure class +mechanics, lead programmers into the false belief that they need not +worry about such things, and occasionally have paradoxical behavior. +

        +These variable-sized object classes are integrated as well as possible +into C++. Most such classes possess converters that allow automatic +coercion both from and to builtin basic types. (e.g., char* to and from +String, long int to and from Integer, etc.). There are pro's and con's +to circular converters, since they can sometimes lead to the conversion +from a builtin type through to a class function and back to a builtin +type without any special attention on the part of the programmer, both +for better and worse. +

        +Most of these classes also provide special-case operators and functions +mixing basic with class types, as a way to avoid constructors in cases +where the operations do not rely on anything special about the +representations. For example, there is a special case concatenation +operator for a String concatenated with a char, since building the +result does not rely on anything about the String header. Again, there +are arguments both for and against this approach. Supporting these cases +adds a non-trivial degree of (mainly inline) function proliferation, but +results in more efficient operations. Efficiency wins out over parsimony +here, as part of the goal to produce classes that provide sufficient +functionality and efficiency so that programmers are not tempted to try +to manipulate or bypass the underlying representations. +

        +

        Some guidelines for using expression-oriented classes

        +

        +The fact that C++ allows operators to be overloaded for user-defined +classes can make programming with library classes like Integer, +String, and so on very convenient. However, it is worth +becoming familiar with some of the inherent limitations and problems +associated with such operators. +

        +Many operators are constructive, i.e., create a new object +based on some function of some arguments. Sometimes the creation +of such objects is wasteful. Most library classes supporting +expressions contain facilities that help you avoid such waste. +

        +For example, for Integer a, b, c; ...; c = a + b + a;, the +plus operator is called to sum a and b, creating a new temporary object +as its result. This temporary is then added with a, creating another +temporary, which is finally copied into c, and the temporaries are then +deleted. In other words, this code might have an effect similar to +Integer a, b, c; ...; Integer t1(a); t1 += b; Integer t2(t1); +t2 += a; c = t2;. +

        +For small objects, simple operators, and/or non-time/space critical +programs, creation of temporaries is not a big problem. However, often, +when fine-tuning a program, it may be a good idea to rewrite such +code in a less pleasant, but more efficient manner. +

        +For builtin types like ints, and floats, C and C++ compilers already +know how to optimize such expressions to reduce the need for +temporaries. Unfortunately, this is not true for C++ user defined +types, for the simple (but very annoying, in this context) reason that +nothing at all is guaranteed about the semantics of overloaded operators +and their interrelations. For example, if the above expression just +involved ints, not Integers, a compiler might internally convert the +statement into something like c += a; c += b; c+= a; , or +perhaps something even more clever. But since C++ does not know that +Integer operator += has any relation to Integer operator +, A C++ +compiler cannot do this kind of expression optimization itself. +

        +In many cases, you can avoid construction of temporaries simply by +using the assignment versions of operators whenever possible, since +these versions create no temporaries. However, for maximum flexibility, +most classes provide a set of "embedded assembly code" procedures +that you can use to fully control time, space, and evaluation strategies. +Most of these procedures are "three-address" procedures that take +two const source arguments, and a destination argument. The +procedures perform the appropriate actions, placing the results in +the destination (which is may involve overwriting old contents). These +procedures are designed to be fast and robust. In particular, aliasing +is always handled correctly, so that, for example +add(x, x, x); is perfectly OK. (The names of these procedures +are listed along with the classes.) +

        +For example, suppose you had an Integer expression + a = (b - a) * -(d / c); +

        +This would be compiled as if it were + Integer t1=b-a; Integer t2=d/c; Integer t3=-t2; Integer t4=t1*t3; a=t4; +

        +But, with some manual cleverness, you might yourself some up with + sub(a, b, a); mul(a, d, a); div(a, c, a); +

        +A related phenomenon occurs when creating your own constructive +functions returning instances of such types. Suppose you wanted +to write function +Integer f(const Integer& a) { Integer r = a; r += a; return r; } +

        +This function, when called (as in a = f(a); ) demonstrates a +similar kind of wasted copy. The returned value r must be copied +out of the function before it can be used by the caller. In GNU +C++, there is an alternative via the use of named return values. +Named return values allow you to manipulate the returned object +directly, rather than requiring you to create a local inside +a function and then copy it out as the returned value. In this +example, this can be done via +Integer f(const Integer& a) return r(a) { r += a; return; } +

        +A final guideline: The overloaded operators are very convenient, and +much clearer to use than procedural code. It is almost always a good +idea to make it right, then make it fast, by translating +expression code into procedural code after it is known to be correct. +

        +

        Pseudo-indexes

        +

        +Many useful classes operate as containers of elements. Techniques for +accessing these elements from a container differ from class to class. +In the GNU C++ library, access methods have been partially standardized +across different classes via the use of pseudo-indexes called +Pixes. A Pix acts in some ways like an index, and in some +ways like a pointer. (Their underlying representations are just +void* pointers). A Pix is a kind of "key" that is +translated into an element access by the class. In virtually all cases, +Pixes are pointers to some kind internal storage cells. The +containers use these pointers to extract items. +

        +Pixes support traversal and inspection of elements in a +collection using analogs of array indexing. However, they are +pointer-like in that 0 is treated as an invalid Pix, and +unsafe insofar as programmers can attempt to access nonexistent elements +via dangling or otherwise invalid Pixes without first checking +for their validity. +

        +In general it is a very bad idea to perform traversals in the the midst +of destructive modifications to containers. +

        +Typical applications might include code using the idiom +

        +for (Pix i = a.first(); i != 0; a.next(i)) use(a(i));
+
        +for some container a and function use. +

        +Classes supporting the use of Pixes always contain the following +methods, assuming a container a of element types of Base. +

        +

        +

        +

        Pix i = a.first() +
        Set i to index the first element of a or 0 if a is empty. +

        +

        a.next(i) +
        advance i to the next element of a or 0 if there is no next element; +

        +

        Base x = a(i); a(i) = x; +
        a(i) returns a reference to the element indexed by i. +

        +

        int present = a.owns(i) +
        returns true if Pix i is a valid Pix in a. This is often a +relatively slow operation, since the collection must usually +traverse through elements to see if any correspond to the Pix. +

        +

        +

        +Some container classes also support backwards traversal via +

        +

        +
        Pix i = a.last() +
        Set i to the last element of a or 0 if a is empty. +

        +

        a.prev(i) +
        sets i to the previous element in a, or 0 if there is none. +
        +

        +Collections supporting elements with an equality operation possess +

        +

        +
        Pix j = a.seek(x) +
        sets j to the index of the first occurrence of x, or 0 if x is +not contained in a. +
        +

        +Bag classes possess +

        +

        +
        Pix j = a.seek(x, Pix from = 0) +
        sets j to the index of the next occurrence of x following i, +or 0 if x is not contained in a. If i == 0, the first occurrence +is returned. +
        +

        +Set, Bag, and PQ classes possess +

        +

        +
        Pix j = a.add(x) (or a.enq(x) for priority queues) +
        add x to the collection, returning its Pix. The Pix of an item +can change in collections where further additions and deletions +involve the actual movement of elements (currently in OXPSet, +OXPBag, XPPQ, VOHSet), but in all other cases, an item's Pix may +be considered a permanent key to its location. +
        +

        Header files for interfacing C++ to C

        +

        +The following files are provided so that C++ programmers may +invoke common C library and system calls. The names and contents +of these files are subject to change in order to be compatible +with the forthcoming GNU C library. Other files, not listed +here, are simply C++-compatible interfaces to corresponding C +library files. +

        +

        +
        `values.h' +
        A collection of constants defining the numbers of bits in builtin +types, minimum and maximum values, and the like. Most names are +the same as those found in `values.h' found on Sun systems. +

        +

        `std.h' +
        A collection of common system calls and `libc.a' functions. +Only those functions that can be declared without introducing +new type definitions (socket structures, for example) are +provided.

        +

        `string.h' +
        This file merely includes `<std.h>', where string function +prototypes are declared. This is a workaround for the fact that +system `string.h' and `strings.h' files often differ +in contents. +

        +

        `osfcn.h' +
        This file merely includes `<std.h>', where system function +prototypes are declared. +

        +

        `libc.h' +
        This file merely includes `<std.h>', where C library function +prototypes are declared. +

        +

        `math.h' +
        A collection of prototypes for functions usually found in +libm.a, plus some #defined constants that appear to be +consistent with those provided in the AT&T version. The value +of HUGE should be checked before using. Declarations of +all common math functions are preceded with overload +declarations, since these are commonly overloaded. +

        +

        `stdio.h' +
        Declaration of FILE (_iobuf), common macros (like +getc), and function prototypes for `libc.a' +functions that operate on FILE*'s. The value +BUFSIZ and the declaration of _iobuf should be +checked before using. +

        +

        `assert.h' +
        C++ versions of assert macros. +

        +

        `generic.h' +
        String concatenation macros useful in creating generic classes. +They are similar in function to the AT&T CC versions. +

        +

        `new.h' +
        Declarations of the default global operator new, the two-argument +placement version, and associated error handlers. +
        +

        +

        +

        Library dynamic allocation primitives

        +

        +Libg++ contains versions of malloc, free, realloc that were +designed to be well-tuned to C++ applications. The source file +`malloc.c' contains some design and implementation details. +Here are the major user-visible differences from most system +malloc routines: +

        +

          +

          +

        1. +These routines overwrite storage of freed space. This +means that it is never permissible to use a delete'd +object in any way. Doing so will either result in trapped +fatal errors or random aborts within malloc, free, or realloc. +

          +

        2. +The routines tend to perform well when a large number +of objects of the same size are allocated and freed. You +may find that it is not worth it to create your +own special allocation schemes in such cases. +

          +

        3. +The library sets top-level operator new() to call malloc and +operator delete() to call free. Of course, you may override these +definitions in C++ programs by creating your own operators that will +take precedence over the library versions. However, if you do so, be +sure to define both operator new() and operator +delete(). +

          +

        4. +These routines do not support the odd convention, maintained by +some versions of malloc, that you may call realloc with a pointer +that has been free'd. +

          +

        5. +The routines automatically perform simple checks on free'd +pointers that can often determine whether users have accidentally +written beyond the boundaries of allocated space, resulting in a fatal +error. +

          +

        6. +The function malloc_usable_size(void* p) returns the number of +bytes actually allocated for p. For a valid pointer (i.e., one +that has been malloc'd or realloc'd but not yet +free'd) this will return a number greater than or equal to the +requested size, else it will normally return 0. Unfortunately, a +non-zero return can not be an absolutely perfect indication of lack of +error. If a chunk has been free'd but then re-allocated for a +different purpose somewhere elsewhere, then malloc_usable_size +will return non-zero. Despite this, the function can be very valuable +for performing run-time consistency checks. +

          +

        7. +malloc requires 8 bytes of overhead per allocated chunk, plus a +mmaximum alignment adjustment of 8 bytes. The number of bytes of usable +space is exactly as requested, rounded to the nearest 8 byte boundary. +

          +

        8. +The routines do not contain any synchronization support for +multiprocessing. If you perform global allocation on a shared +memory multiprocessor, you should disable compilation and use +of libg++ malloc in the distribution `Makefile' and use your +system version of malloc. +

          +

        +

        +

        The new input/output classes

        +

        +The iostream classes implement most of the features of AT&T +version 2.0 iostream library classes, and most of the features +of the ANSI X3J16 library draft (which is based on the AT&T design). +These classes are available in libg++ for convenience and for +compatibility with older releases; however, since the iostream classes +are licensed under less stringent terms than libg++, they are now +also available in a separate library called libio---and +documented in a separate manual, corresponding to that library. +

        +See section 'Introduction' in The GNU C++ Iostream Library. +

        +

        The old I/O library

        +

        +WARNING: This chapter describes classes that are obsolete. +These classes are normally not available when libg++ +is installed normally. The sources are currently included +in the distribution, and you can configure libg++ to use +these classes instead of the new iostream classes. +This is only a temporary measure; you should convert your +code to use iostreams as soon as possible. The iostream +classes provide some compatibility support, but it is +very incomplete (there is no longer a File class). +

        +

        File-based classes

        + +The File class supports basic IO on Unix files. Operations are +based on common C stdio library functions. +

        +File serves as the base class for istreams, ostreams, and other +derived classes. It contains the interface between the Unix stdio file +library and these more structured classes. Most operations are implemented +as simple calls to stdio functions. File class operations are also fully +compatible with raw system file reads and writes (like the system +read and lseek calls) when buffering is disabled (see below). +The FILE* stdio file pointer is, however maintained as protected. +Classes derived from File may only use the IO operations provided by File, +which encompass essentially all stdio capabilities. +

        +The class contains four general kinds of functions: methods for binding +Files to physical Unix files, basic IO methods, file and buffer +control methods, and methods for maintaining logical and physical file +status. +

        +Binding and related tasks are accomplished via File constructors and +destructors, and member functions open, close, remove, filedesc, +name, setname. +

        +If a file name is provided in a constructor or open, it is +maintained as class variable nm and is accessible +via name. If no name is provided, then nm remains +null, except that Files bound to the default files stdin, +stdout, and stderr are automatically given the names +(stdin), (stdout), (stderr) respectively. +The function setname may be used to change the +internal name of the File. This does not change the name +of the physical file bound to the File. + +The member function close closes a file. The +~File destructor closes a file if it is open, except +that stdin, stdout, and stderr are flushed but left open for +the system to close on program exit since some systems may +require this, and on others it does not matter. remove +closes the file, and then deletes it if possible by calling the +system function to delete the file with the name provided in +the nm field. +

        +

        Basic IO

        +

        +

          +

          +

        • +read and write perform binary IO via stdio +fread and fwrite. +

          +

        • +get and put for chars invoke stdio getc +and putc macros. +

          +

        • +put(const char* s) outputs a null-terminated string via +stdio fputs. +

          +

        • +unget and putback are synonyms. Both call stdio +ungetc. +

          +

        +

        +

        File Control

        +

        +flush, seek, tell, and tell call the +corresponding stdio functions. +

        +flush(char) and fill() call stdio _flsbuf +and _filbuf respectively. +

        +setbuf is mainly useful to turn off buffering in cases +where nonsequential binary IO is being performed. raw is a +synonym for setbuf(_IONBF). After a f.raw(), using +the stdio functions instead of the system read, write, +etc., calls entails very little overhead. Moreover, these become +fully compatible with intermixed system calls (e.g., +lseek(f.filedesc(), 0, 0)). While intermixing File +and system IO calls is not at all recommended, this technique +does allow the File class to be used in conjunction with +other functions and libraries already set up to operate on file +descriptors. setbuf should be called at most once after a +constructor or open, but before any IO. +

        +

        File Status

        +

        +File status is maintained in several ways. +

        +A File may be checked for accessibility via +is_open(), which returns true if the File is bound to a +usable physical file, readable(), which returns true if +the File can be read from (opened for reading, and not in a +_fail state), or writable(), which returns true if the +File can be written to. +

        +File operations return their status via two means: failure and +success are represented via the logical state. Also, the +return values of invoked stdio and system functions that +return useful numeric values (not just failure/success flags) +are held in a class variable accessible via iocount. +(This is useful, for example, in determining the number of +items actually read by the read function.) +

        +Like the AT&T i/o-stream classes, but unlike the description in +the Stroustrup book, p238, rdstate() returns the bitwise +OR of _eof, _fail and _bad, not necessarily +distinct values. The functions eof(), fail(), +bad(), and good() can be used to test for each of +these conditions independently. +

        +_fail becomes set for any input operation that could not +read in the desired data, and for other failed operations. As +with all Unix IO, _eof becomes true only when an input +operations fails because of an end of file. Therefore, +_eof is not immediately true after the last successful +read of a file, but only after one final read attempt. Thus, for +input operations, _fail and _eof almost always +become true at the same time. bad is set for unbound +files, and may also be set by applications in order to communicate +input corruption. Conversely, _good is defined as 0 and +is returned by rdstate() if all is well. +

        +The state may be modified via clear(flag), which, +despite its name, sets the corresponding state_value flag. +clear() with no arguments resets the state to _good. +failif(int cond) sets the state to _fail only if +cond is true. +

        +Errors occuring during constructors and file opens also invoke the +function error. error in turn calls a resetable error +handling function pointed to by the non-member global variable +File_error_handler only if a system error has been generated. +Since error cannot tell if the current system error is actually +responsible for a failure, it may at times print out spurious messages. +Three error handlers are provided. The default, +verbose_File_error_handler calls the system function +perror to print the corresponding error message on standard +error, and then returns to the caller. quiet_File_error_handler +does nothing, and simply returns. fatal_File_error_handler +prints the error and then aborts execution. These three handlers, or any +other user-defined error handlers can be selected via the non-member +function set_File_error_handler. +

        +All read and write operations communicate either logical or +physical failure by setting the _fail flag. All further +operations are blocked if the state is in a _fail or_bad +condition. Programmers must explicitly use clear() to +reset the state in order to continue IO processing after +either a logical or physical failure. C programmers who are +unfamiliar with these conventions should note that, unlike +the stdio library, File functions indicate IO success, +status, or failure solely through the state, not via return values of +the functions. The void* operator or rdstate() +may be used to test success. In particular, according to c++ +conversion rules, the void* coercion is automatically +applied whenever the File& return value of any File +function is tested in an if or while. Thus, +for example, an easy way to copy all of stdin to stdout until +eof (at which point get fails) or some error is +char c; while(cin.get(c) && cout.put(c));. +

        +The current version of istreams and ostreams differs significantly +from previous versions in order to obtain compatibility with +AT&T 1.2 streams. Most code using previous versions should still +work. However, the following features of File are not +incorporated in streams (they are still present in File): +scan(const char* fmt...), remove(), read(), write(), +setbuf(), raw(). Additionally, the feature of previous streams +that allowed free intermixing of stream and stdio input and output +is no longer guaranteed to always behave as desired. +

        +

        The Obstack class

        +

        +The Obstack class is a simple rewrite of the C obstack macros and +functions provided in the GNU CC compiler source distribution. +

        +Obstacks provide a simple method of creating and maintaining a string +table, optimized for the very frequent task of building strings +character-by-character, and sometimes keeping them, and sometimes +not. They seem especially useful in any parsing application. One of the +test files demonstrates usage. +

        +A brief summary: +

        +

        +

        grow +
        places something on the obstack without committing to wrap +it up as a single entity yet. +

        +

        finish +
        wraps up a constructed object as a single entity, +and returns the pointer to its start address. +

        +

        copy +
        places things on the obstack, and does wrap them up. +copy is always equivalent to first grow, then finish. +

        +

        free +
        deletes something, and anything else put on the obstack since its creation. +
        +

        +The other functions are less commonly needed: +

        +
        blank +
        is like grow, except it just grows the space by size units +without placing anything into this space +
        alloc +
        is like blank, but it wraps up the object and returns its starting +address. +
        chunk_size, base, next_free, alignment_mask, size, room +
        returns the appropriate class variables. +
        grow_fast +
        places a character on the obstack without checking if there is enough room. +
        blank_fast +
        like blank, but without checking if there is enough room. +
        shrink(int n) +
        shrink the current chunk by n bytes. +
        contains(void* addr) +
        returns true if the Obstack holds the address addr. +
        +

        +Here is a lightly edited version of the original C documentation: +

        +These functions operate a stack of objects. Each object starts life +small, and may grow to maturity. (Consider building a word syllable +by syllable.) An object can move while it is growing. Once it has +been "finished" it never changes address again. So the "top of the +stack" is typically an immature growing object, while the rest of the +stack is of mature, fixed size and fixed address objects. +

        +These routines grab large chunks of memory, using the GNU C++ new +operator. On occasion, they free chunks, via delete. +

        +Each independent stack is represented by a Obstack. +

        +One motivation for this package is the problem of growing char strings +in symbol tables. Unless you are a "fascist pig with a read-only mind" +[Gosper's immortal quote from HAKMEM item 154, out of context] you +would not like to put any arbitrary upper limit on the length of your +symbols. +

        +In practice this often means you will build many short symbols and a +few long symbols. At the time you are reading a symbol you don't know +how long it is. One traditional method is to read a symbol into a +buffer, realloc()ating the buffer every time you try to read a +symbol that is longer than the buffer. This is beaut, but you still will +want to copy the symbol from the buffer to a more permanent +symbol-table entry say about half the time. +

        +With obstacks, you can work differently. Use one obstack for all symbol +names. As you read a symbol, grow the name in the obstack gradually. +When the name is complete, finalize it. Then, if the symbol exists already, +free the newly read name. +

        +The way we do this is to take a large chunk, allocating memory from +low addresses. When you want to build a symbol in the chunk you just +add chars above the current "high water mark" in the chunk. When you +have finished adding chars, because you got to the end of the symbol, +you know how long the chars are, and you can create a new object. +Mostly the chars will not burst over the highest address of the chunk, +because you would typically expect a chunk to be (say) 100 times as +long as an average object. +

        +In case that isn't clear, when we have enough chars to make up +the object, they are already contiguous in the chunk (guaranteed) +so we just point to it where it lies. No moving of chars is +needed and this is the second win: potentially long strings need +never be explicitly shuffled. Once an object is formed, it does not +change its address during its lifetime. +

        +When the chars burst over a chunk boundary, we allocate a larger +chunk, and then copy the partly formed object from the end of the old +chunk to the beginning of the new larger chunk. We then carry on +accreting characters to the end of the object as we normally would. +

        +A special version of grow is provided to add a single char at a time +to a growing object. +

        +Summary: +

        +

          +
        • +We allocate large chunks. +
        • +We carve out one object at a time from the current chunk. +
        • +Once carved, an object never moves. +
        • +We are free to append data of any size to the currently growing object. +
        • +Exactly one object is growing in an obstack at any one time. +
        • +You can run one obstack per control block. +
        • +You may have as many control blocks as you dare. +
        • +Because of the way we do it, you can `unwind' a obstack back to a +previous state. (You may remove objects much as you would with a stack.) +
        +

        +The obstack data structure is used in many places in the GNU C++ compiler. +

        +Differences from the the GNU C version +

          +
        1. +The obvious differences stemming from the use of classes and +inline functions instead of structs and macros. The C +init and begin macros are replaced by constructors. +

          +

        2. +Overloaded function names are used for grow (and others), +rather than the C grow, grow0, etc. +

          +

        3. +All dynamic allocation uses the the built-in new operator. +This restricts flexibility by a little, but maintains compatibility +with usual C++ conventions. +

          +

        4. +There are now two versions of finish: +

          +

            +
          1. +finish() behaves like the C version. +

            +

          2. +finish(char terminator) adds terminator, and then calls +finish(). This enables the normal invocation of finish(0) to +wrap up a string being grown character-by-character. +
          +

          +

        5. +There are special versions of grow(const char* s) and +copy(const char* s) that add the null-terminated string s +after computing its length. +

          +

        6. +The shrink and contains functions are provided. +

          +

        +

        +

        The AllocRing class

        +

        +An AllocRing is a bounded ring (circular list), each of whose elements +contains a pointer to some space allocated via new +char[some_size]. The entries are used cyclicly. The size, n, of the +ring is fixed at construction. After that, every nth use of the ring +will reuse (or reallocate) the same space. AllocRings are needed in +order to temporarily hold chunks of space that are needed transiently, +but across constructor-destructor scopes. They mainly useful for storing +strings containing formatted characters to print across various +functions and coercions. These strings are needed across routines, so +may not be deleted in any one of them, but should be recovered at some +point. In other words, an AllocRing is an extremely simple minded +garbage collection mechanism. The GNU C++ library used to use one +AllocRing for such formatting purposes, but it is being phased out, +and is now only used by obsolete functions. +These days, AllocRings are probably not very useful. +

        +Support includes: +

        +

        +

        +

        AllocRing a(int n) +
        constructs an Alloc ring with n entries, all null. +

        +

        void* mem = a.alloc(sz) +
        moves the ring pointer to the next entry, and reuses the space +if their is enough, also allocates space via new char[sz]. +

        +

        int present = a.contains(void* ptr) +
        returns true if ptr is held in one of the ring entries. +

        +

        a.clear() +
        deletes all space pointed to in any entry. This is called +automatically upon destruction. +

        +

        a.free(void* ptr) +
        If ptr is one of the entries, calls delete of the pointer, +and resets to entry pointer to null. +

        +

        +

        +

        The String class

        +

        +The String class is designed to extend GNU C++ to support +string processing capabilities similar to those in languages like +Awk. The class provides facilities that ought to be convenient +and efficient enough to be useful replacements for char* +based processing via the C string library (i.e., strcpy, +strcmp, etc.) in many applications. Many details about String +representations are described in the Representation section. +

        +A separate SubString class supports substring extraction +and modification operations. This is implemented in a way that +user programs never directly construct or represent substrings, +which are only used indirectly via String operations. +

        +Another separate class, Regex is also used indirectly via String +operations in support of regular expression searching, matching, and the +like. The Regex class is based entirely on the GNU Emacs regex +functions. See section 'Syntax of Regular Expressions' in GNU Emacs Manual, for a full +explanation of regular expression syntax. (For implementation details, +see the internal documentation in files `regex.h' and +`regex.c'.) +

        +

        Constructors

        +

        +Strings are initialized and assigned as in the following examples: +

        +

        +

        +

        String x; String y = 0; String z = ""; +
        Set x, y, and z to the nil string. Note that either 0 or "" may +always be used to refer to the nil string. +

        +

        String x = "Hello"; String y("Hello"); +
        Set x and y to a copy of the string "Hello". +

        +

        String x = 'A'; String y('A'); +
        Set x and y to the string value "A" +

        +

        String u = x; String v(x); +
        Set u and v to the same string as String x +

        +

        String u = x.at(1,4); String v(x.at(1,4)); +
        Set u and v to the length 4 substring of x starting at position 1 +(counting indexes from 0). +

        +

        String x("abc", 2); +
        Sets x to "ab", i.e., the first 2 characters of "abc". +

        +

        String x = dec(20); +
        Sets x to "20". As here, Strings may be initialized or assigned +the results of any char* function. +

        +

        +

        +There are no directly accessible forms for declaring SubString +variables. +

        +The declaration Regex r("[a-zA-Z_][a-zA-Z0-9_]*"); creates +a compiled regular expression suitable for use in String +operations described below. (In this case, one that matches any +C++ identifier). The first argument may also be a String. +Be careful in distinguishing the role of backslashes in quoted +GNU C++ char* constants versus those in Regexes. For example, a Regex +that matches either one or more tabs or all strings beginning +with "ba" and ending with any number of occurrences of "na" +could be declared as Regex r = "\\(\t+\\)\\|\\(ba\\(na\\)*\\)" +Note that only one backslash is needed to signify the tab, but +two are needed for the parenthesization and virgule, since the +GNU C++ lexical analyzer decodes and strips backslashes before +they are seen by Regex. +

        +There are three additional optional arguments to the Regex constructor +that are less commonly useful: +

        +

        +
        fast (default 0) +
        fast may be set to true (1) if the Regex should be +"fast-compiled". This causes an additional compilation step that +is generally worthwhile if the Regex will be used many times. +

        +

        bufsize (default max(40, length of the string)) +
        This is an estimate of the size of the internal compiled +expression. Set it to a larger value if you know that the +expression will require a lot of space. If you do not know, +do not worry: realloc is used if necessary. +

        +

        transtable (default none == 0) +
        The address of a byte translation table (a char[256]) that +translates each character before matching. +

        +

        +

        +As a convenience, several Regexes are predefined and usable in +any program. Here are their declarations from `String.h'. +

        +

        +extern Regex RXwhite;      // = "[ \n\t]+"
+extern Regex RXint;        // = "-?[0-9]+"
+extern Regex RXdouble;     // = "-?\\(\\([0-9]+\\.[0-9]*\\)\\|
+                           //    \\([0-9]+\\)\\|
+                           //    \\(\\.[0-9]+\\)\\)
+                           //    \\([eE][---+]?[0-9]+\\)?"
+extern Regex RXalpha;      // = "[A-Za-z]+"
+extern Regex RXlowercase;  // = "[a-z]+"
+extern Regex RXuppercase;  // = "[A-Z]+"
+extern Regex RXalphanum;   // = "[0-9A-Za-z]+"
+extern Regex RXidentifier; // = "[A-Za-z_][A-Za-z0-9_]*"
+
+
        +

        +

        Examples

        +

        +Most String class capabilities are best shown via example. +The examples below use the following declarations. +

        +

        +    String x = "Hello";
+    String y = "world";
+    String n = "123";
+    String z;
+    char*  s = ",";
+    String lft, mid, rgt;
+    Regex  r = "e[a-z]*o";
+    Regex  r2("/[a-z]*/");
+    char   c;
+    int    i, pos, len;
+    double f;
+    String words[10];
+    words[0] = "a";
+    words[1] = "b";
+    words[2] = "c";
+    
+
        +

        +

        Comparing, Searching and Matching

        +

        +The usual lexicographic relational operators (==, !=, <, <=, >, >=) +are defined. A functional form compare(String, String) is also +provided, as is fcompare(String, String), which compares +Strings without regard for upper vs. lower case. +

        +All other matching and searching operations are based on some form of the +(non-public) match and search functions. match and +search differ in that match attempts to match only at the +given starting position, while search starts at the position, and +then proceeds left or right looking for a match. As seen in the following +examples, the second optional startpos argument to functions using +match and search specifies the starting position of the +search: If non-negative, it results in a left-to-right search starting at +position startpos, and if negative, a right-to-left search starting +at position x.length() + startpos. In all cases, the index returned +is that of the beginning of the match, or -1 if there is no match. +

        +Three String functions serve as front ends to search and match. +index performs a search, returning the index, matches performs +a match, returning nonzero (actually, the length of the match) on success, +and contains is a boolean function performing either a search or +match, depending on whether an index argument is provided: +

        +

        +

        +

        x.index("lo") +
        returns the zero-based index of the leftmost occurrence of +substring "lo" (3, in this case). The argument may be a +String, SubString, char, char*, or Regex. +

        +

        x.index("l", 2) +
        returns the index of the first of the leftmost occurrence of "l" +found starting the search at position x[2], or 2 in this case. +

        +

        x.index("l", -1) +
        returns the index of the rightmost occurrence of "l", or 3 here. +

        +

        x.index("l", -3) +
        returns the index of the rightmost occurrence of "l" found by +starting the search at the 3rd to the last position of x, +returning 2 in this case. +

        +

        pos = r.search("leo", 3, len, 0) +
        returns the index of r in the char* string of length 3, +starting at position 0, also placing the length of the match +in reference parameter len. +

        +

        x.contains("He") +
        returns nonzero if the String x contains the substring "He". The +argument may be a String, SubString, char, char*, or Regex. +

        +

        x.contains("el", 1) +
        returns nonzero if x contains the substring "el" at position 1. +As in this example, the second argument to contains, +if present, means to match the substring only at that position, +and not to search elsewhere in the string. +

        +

        x.contains(RXwhite); +
        returns nonzero if x contains any whitespace (space, tab, or +newline). Recall that RXwhite is a global whitespace Regex. +

        +

        x.matches("lo", 3) +
        returns nonzero if x starting at position 3 exactly matches "lo", with +no trailing characters (as it does in this example). +

        +

        x.matches(r) +
        returns nonzero if String x as a whole matches Regex r. +

        +

        int f = x.freq("l") +
        returns the number of distinct, nonoverlapping matches to the argument +(2 in this case). +

        +

        +

        +

        Substring extraction

        +

        +Substrings may be extracted via the at, before, +through, from, and after functions. +These behave as either lvalues or rvalues. +

        +

        +

        +

        z = x.at(2, 3) +
        sets String z to be equal to the length 3 substring of String x +starting at zero-based position 2, setting z to "llo" in this +case. A nil String is returned if the arguments don't make sense. +

        +

        x.at(2, 2) = "r" +
        Sets what was in positions 2 to 3 of x to "r", setting x to +"Hero" in this case. As indicated here, SubString assignments may +be of different lengths. +

        +

        x.at("He") = "je"; +
        x("He") is the substring of x that matches the first occurrence of +it's argument. The substitution sets x to "jello". If "He" did +not occur, the substring would be nil, and the assignment would +have no effect. +

        +

        x.at("l", -1) = "i"; +
        replaces the rightmost occurrence of "l" with "i", setting x to +"Helio". +

        +

        z = x.at(r) +
        sets String z to the first match in x of Regex r, or "ello" in this +case. A nil String is returned if there is no match. +

        +

        z = x.before("o") +
        sets z to the part of x to the left of the first occurrence of +"o", or "Hell" in this case. The argument may also be a String, +SubString, or Regex. (If there is no match, z is set to "".) +

        +

        x.before("ll") = "Bri"; +
        sets the part of x to the left of "ll" to "Bri", setting x to +"Brillo". +

        +

        z = x.before(2) +
        sets z to the part of x to the left of x[2], or "He" in this +case. +

        +

        z = x.after("Hel") +
        sets z to the part of x to the right of "Hel", or "lo" in this +case. +

        +

        z = x.through("el") +
        sets z to the part of x up and including "el", or "Hel" in this case. +

        +

        z = x.from("el") +
        sets z to the part of x from "el" to the end, or "ello" in this case. +

        +

        x.after("Hel") = "p"; +
        sets x to "Help"; +

        +

        z = x.after(3) +
        sets z to the part of x to the right of x[3] or "o" in this case. +

        +

        z = " ab c"; z = z.after(RXwhite) +
        sets z to the part of its old string to the right of the first +group of whitespace, setting z to "ab c"; Use gsub(below) to +strip out multiple occurrences of whitespace or any pattern. +

        +

        x[0] = 'J'; +
        sets the first element of x to 'J'. x[i] returns a reference to +the ith element of x, or triggers an error if i is out of range. +

        +

        common_prefix(x, "Help") +
        returns the String containing the common prefix of the two Strings +or "Hel" in this case. +

        +

        common_suffix(x, "to") +
        returns the String containing the common suffix of the two Strings +or "o" in this case. +

        +

        +

        +

        Concatenation

        +

        +

        +

        +

        z = x + s + ' ' + y.at("w") + y.after("w") + "."; +
        sets z to "Hello, world." +

        +

        x += y; +
        sets x to "Helloworld" +

        +

        cat(x, y, z) +
        A faster way to say z = x + y. +

        +

        cat(z, y, x, x) +
        Double concatenation; A faster way to say x = z + y + x. +

        +

        y.prepend(x); +
        A faster way to say y = x + y. +

        +

        z = replicate(x, 3); +
        sets z to "HelloHelloHello". +

        +

        z = join(words, 3, "/") +
        sets z to the concatenation of the first 3 Strings in String +array words, each separated by "/", setting z to "a/b/c" in this +case. The last argument may be "" or 0, indicating no separation. +

        +

        +

        +

        Other manipulations

        +

        +

        +

        +

        z = "this string has five words"; i = split(z, words, 10, RXwhite); +
        sets up to 10 elements of String array words to the parts of z +separated by whitespace, and returns the number of parts actually +encountered (5 in this case). Here, words[0] = "this", words[1] = +"string", etc. The last argument may be any of the usual. +If there is no match, all of z ends up in words[0]. The words array +is not dynamically created by split. +

        +

        int nmatches x.gsub("l","ll") +
        substitutes all original occurrences of "l" with "ll", setting x +to "Hellllo". The first argument may be any of the usual, +including Regex. If the second argument is "" or 0, all +occurrences are deleted. gsub returns the number of matches +that were replaced. +

        +

        z = x + y; z.del("loworl"); +
        deletes the leftmost occurrence of "loworl" in z, setting z to +"Held". +

        +

        z = reverse(x) +
        sets z to the reverse of x, or "olleH". +

        +

        z = upcase(x) +
        sets z to x, with all letters set to uppercase, setting z to "HELLO" +

        +

        z = downcase(x) +
        sets z to x, with all letters set to lowercase, setting z to "hello" +

        +

        z = capitalize(x) +
        sets z to x, with the first letter of each word set to uppercase, +and all others to lowercase, setting z to "Hello" +

        +

        x.reverse(), x.upcase(), x.downcase(), x.capitalize() +
        in-place, self-modifying versions of the above. +

        +

        +

        Reading, Writing and Conversion

        +

        +

        +

        +

        cout << x +
        writes out x. +

        +

        cout << x.at(2, 3) +
        writes out the substring "llo". +

        +

        cin >> x +
        reads a whitespace-bounded string into x. +

        +

        x.length() +
        returns the length of String x (5, in this case). +

        +

        s = (const char*)x +
        can be used to extract the char* char array. This +coercion is useful for sending a String as an argument to any +function expecting a const char* argument (like +atoi, and File::open). This operator must be +used with care, since the conversion returns a pointer +to String internals without copying the characters: +The resulting (char*) is only valid until +the next String operation, and you must not modify it. +(The conversion is defined to return a const +value so that GNU C++ will produce warning and/or error +messages if changes are attempted.) +

        +

        +

        +

        The Integer class.

        +

        +The Integer class provides multiple precision integer arithmetic +facilities. Some representation details are discussed in the +Representation section. +

        +Integers may be up to b * ((1 << b) - 1) bits long, where +b is the number of bits per short (typically 1048560 bits when +b = 16). The implementation assumes that a long is at least +twice as long as a short. This assumption hides beneath almost all +primitive operations, and would be very difficult to change. It also relies +on correct behavior of unsigned arithmetic operations. +

        +Some of the arithmetic algorithms are very loosely based on those +provided in the MIT Scheme `bignum.c' release, which is +Copyright (c) 1987 Massachusetts Institute of Technology. Their use +here falls within the provisions described in the Scheme release. +

        +Integers may be constructed in the following ways: +

        +

        +

        Integer x; +
        Declares an uninitialized Integer. +

        +

        Integer x = 2; Integer y(2); +
        Set x and y to the Integer value 2; +

        +

        Integer u(x); Integer v = x; +
        Set u and v to the same value as x. +

        +

        +

        + +Method: long Integer::as_long() const

        +Used to coerce an Integer back into longs via the long +coercion operator. If the Integer cannot fit into a long, this returns +MINLONG or MAXLONG (depending on the sign) where MINLONG is the most +negative, and MAXLONG is the most positive representable long. +

        + +Method: int Integer::fits_in_long() const

        +Returns true iff the Integer is < MAXLONG and > MINLONG. +

        + +Method: double Integer::as_double() const

        +Coerce the Integer to a double, with potential +loss of precision. ++/-HUGE is returned if the Integer cannot fit into a double. +

        + +Method: int Integer::fits_in_double() const

        +Returns true iff the Integer can fit into a double. +

        +All of the usual arithmetic operators are provided (+, -, *, /, +%, +=, ++, -=, --, *=, /=, %=, ==, !=, <, <=, >, >=). All operators +support special versions for mixed arguments of Integers and regular +C++ longs in order to avoid useless coercions, as well as to allow +automatic promotion of shorts and ints to longs, so that they may be +applied without additional Integer coercion operators. The only +operators that behave differently than the corresponding int or long +operators are ++ and --. Because C++ does not +distinguish prefix from postfix application, these are declared as +void operators, so that no confusion can result from applying +them as postfix. Thus, for Integers x and y, ++x; y = x; is +correct, but y = ++x; and y = x++; are not. +

        +Bitwise operators (~, &, |, ^, <<, +>>, &=, |=, ^=, <<=, >>=) are +also provided. However, these operate on sign-magnitude, rather than +two's complement representations. The sign of the result is arbitrarily +taken as the sign of the first argument. For example, Integer(-3) +& Integer(5) returns Integer(-1), not -3, as it would using +two's complement. Also, ~, the complement operator, complements +only those bits needed for the representation. Bit operators are also +provided in the BitSet and BitString classes. One of these classes +should be used instead of Integers when the results of bit manipulations +are not interpreted numerically. +

        +The following utility functions are also provided. (All arguments +are Integers unless otherwise noted). +

        + +Function: void divide(const Integer& x, const Integer& y, Integer& q, Integer& r)

        +Sets q to the quotient and r to the remainder of x and y. +(q and r are returned by reference). +

        + +Function: Integer pow(const Integer& x, const Integer& p)

        +Returns x raised to the power p. +

        + +Function: Integer Ipow(long x, long p)

        +Returns x raised to the power p. +

        + +Function: Integer gcd(const Integer& x, const Integer& p)

        + +Function: Integer lcm(const Integer& x, const Integer& p)

        +Returns the least common multiple of x and y. +

        + +Function: Integer abs(const Integer& x

        +Returns the absolute value of x. +

        + +Method: void Integer::negate()

        +Negates this in place. +

        +

        int sign(x) +
        returns -1 if x is negative, 0 if zero, else +1. +Using if (sign(x) == 0) is a generally faster method +of testing for zero than using relational operators. +

        +

        int even(x) +
        returns true if x is an even number +

        +

        int odd(x) +

        +

        void clearbit(Integer& x, long b) +

        +

        int testbit(Integer x, long b) +
        returns true if the b'th bit of x is 1. +

        +

        converts the base base char* string into its Integer form. +

        +

        void Integer::printon(ostream& s, int base = 10, int width = 0); +
        prints the ascii string value of (*this) as a base base +number, in field width at least width. +

        +

        prints x in base ten format. +

        +

        istream >> x; +
        reads x as a base ten number. +

        +

        int compare(Integer x, Integer y) +
        returns a negative number if x<y, zero if x==y, or positive if x>y. +

        +

        int ucompare(Integer x, Integer y) +
        like compare, but performs unsigned comparison. +

        +

        add(x, y, z) +

        +

        div(x, y, z) +
        A faster way to say z = x / y. +

        +

        mod(x, y, z) +
        A faster way to say z = x % y. +

        +

        and(x, y, z) +

        +

        +

        The Rational Class

        +

        +Class Rational provides multiple precision rational +number arithmetic. All rationals are maintained in simplest +form (i.e., with the numerator and denominator relatively +prime, and with the denominator strictly positive). +Rational arithmetic and relational operators are provided +(+, -, *, /, +=, -=, *=, /=, ==, !=, <, <=, >, >=). +Operations resulting in a rational number with zero denominator +trigger an exception. +

        +Rationals may be constructed and used in the following ways: +

        +

        +

        +

        Rational x; +
        Declares an uninitialized Rational. +

        +

        +

        Rational x = 1.2; +
        Sets x to a Rational value close to 1.2. Any double precision value +may be used to construct a Rational. The Rational will possess +exactly as much precision as the double. Double values that do +not have precise floating point equivalents (like 1.2) produce +similarly imprecise rational values. +

        +

        Rational x(Integer(123), Integer(4567)); +
        Sets x to the Rational value 123/4567. +

        returns the numerator. +

        +

        Integer x.denominator() +
        returns the denominator. +

        +

        Integer floor(x) +
        returns the greatest Integer less than x. +

        +

        Integer ceil(x) +
        returns the least Integer greater than x. +

        +

        Integer trunc(x) +
        returns the Integer part of x. +

        +

        +

        int compare(x, y) +
        returns a negative, zero, or positive number signifying whether x is +less than, equal to, or greater than y. +

        +

        ostream << x; +
        prints x in the form num/den, or just num if the denominator is one. +

        +

        istream >> x; +
        reads x in the form num/den, or just num in which case the +denominator is set to one. +

        +

        add(x, y, z) +
        A faster way to say z = x + y. +

        +

        sub(x, y, z) +
        A faster way to say z = x - y. +

        +

        mul(x, y, z) +
        A faster way to say z = x * y. +

        +

        div(x, y, z) +
        A faster way to say z = x / y. +

        +

        pow(x, y, z) +

        +

        negate(x, z) +
        A faster way to say z = -x. +

        +

        +

        +

        The Complex class.

        +

        +Class Complex is implemented in a way similar to that +described by Stroustrup. In keeping with libg++ conventions, +the class is named Complex, not complex. +Complex arithmetic and relational operators are provided +(+, -, *, /, +=, -=, *=, /=, ==, !=). +Attempted division by (0, 0) triggers an exception. +

        +Complex numbers may be constructed and used in the following ways: +

        +

        +

        +

        returns a Complex with abs of r and arg of t. +

        +

        Complex conj(Complex& x); +
        returns the complex conjugate of x. +

        +

        Complex cos(Complex& x); +
        returns the complex cosine of x. +

        +

        Complex sin(Complex& x); +
        returns the complex sine of x. +

        +

        Complex cosh(Complex& x); +
        returns the complex hyperbolic cosine of x. +

        +

        +

        +

        Fixed precision numbers

        +

        +Classes Fix16, Fix24, Fix32, and Fix48 +support operations on 16, 24, 32, or 48 bit quantities that are +considered as real numbers in the range [-1, +1). Such numbers are +often encountered in digital signal processing applications. The classes +may be be used in isolation or together. Class Fix32 +operations are entirely self-contained. Class Fix16 operations +are self-contained except that the multiplication operation Fix16 +* Fix16 returns a Fix32. Fix24 and Fix48 are +similarly related. +

        +The standard arithmetic and relational operations are supported +(=, +, -, *, /, <<, >>, ++=, -=, *=, /=, <<=, >>=, +==, !=, <, <=, >, >=). +All operations include provisions for special handling in cases where +the result exceeds +/- 1.0. There are two cases that may be handled +separately: "overflow" where the results of addition and subtraction +operations go out of range, and all other "range errors" in which +resulting values go off-scale (as with division operations, and +assignment or initialization with off-scale values). In signal +processing applications, it is often useful to handle these two cases +differently. Handlers take one argument, a reference to the integer +mantissa of the offending value, which may then be manipulated. In +cases of overflow, this value is the result of the (integer) arithmetic +computation on the mantissa; in others it is a fully saturated (i.e., +most positive or most negative) value. Handling may be reset to any of +several provided functions or any other user-defined function via +set_overflow_handler and set_range_error_handler. The +provided functions for Fix16 are as follows (corresponding +functions are also supported for the others). +

        +

        +

        +

        Fix16_overflow_saturate +
        The default overflow handler. Results are "saturated": positive results +are set to the largest representable value (binary 0.111111...), and +negative values to -1.0. +

        +

        Fix16_ignore +
        Performs no action. For overflow, this will allow addition and +subtraction operations to "wrap around" in the same manner +as integer arithmetic, and for saturation, will leave values saturated. +

        +

        Fix16_overflow_warning_saturate +
        Prints a warning message on standard error, then saturates the results. +

        +

        Fix16_warning +
        The default range_error handler. Prints a warning message +on standard error; otherwise leaving the argument unmodified. +

        +

        Fix16_abort +
        prints an error message on standard error, then aborts execution. +

        +

        +

        +In addition to arithmetic operations, the following are provided: +

        +

        +

        +

        Fix16 a = 0.5; +
        Constructs fixed precision objects from double precision values. +Attempting to initialize to a value outside the range invokes +the range_error handler, except, as a convenience, +initialization to 1.0 sets the variable to the most positive +representable value (binary 0.1111111...) without invoking the handler. +

        +

        short& mantissa(a); long& mantissa(b); +
        return a * pow(2, 15) or b * pow(2, 31) as an integer. These +are returned by reference, to enable "manual" data manipulation. +

        +

        double value(a); double value(b); +
        return a or b as floating point numbers. +

        +

        +

        +

        Classes for Bit manipulation

        +

        +libg++ provides several different classes supporting the use +and manipulation of collections of bits in different ways. +

        +

          +

          +

        • +Class Integer provides "integer" semantics. It supports +manipulation of bits in ways that are often useful when treating bit arrays +as numerical (integer) quantities. This class is described elsewhere. +

          +

        • +Class BitSet provides "set" semantics. It supports operations +useful when treating collections of bits as representing potentially +infinite sets of integers. +

          +

        • +Class BitSet32 supports fixed-length BitSets holding exactly +32 bits. +

          +

        • +Class BitSet256 supports fixed-length BitSets holding exactly +256 bits. +

          +

        • +Class BitString provides "string" (or "vector") semantics. +It supports operations useful when treating collections of bits as +strings of zeros and ones. +

          +

        +

        +These classes also differ in the following ways: +

        +

          +

          +

        • +BitSets are logically infinite. Their space is dynamically altered to +adjust to the smallest number of consecutive bits actually required to +represent the sets. Integers also have this property. BitStrings are +logically finite, but their sizes are internally dynamically managed to +maintain proper length. This means that, for example, BitStrings are +concatenatable while BitSets and Integers are not. +

          +

        • +BitSet32 and BitSet256 have precisely the same properties as BitSets, +except that they use constant fixed length bit vectors. +

          +

        • +While all classes support basic unary and binary operations ~, &, +|, ^, -, the semantics differ. BitSets perform bit operations that +precisely mirror those for infinite sets. For example, complementing an +empty BitSet returns one representing an infinite number of set bits. +Operations on BitStrings and Integers operate only on those bits +actually present in the representation. For BitStrings and Integers, +the the & operation returns a BitString with a length equal to +the minimum length of the operands, and |, ^ return one with +length of the maximum. +

          +

        • +Only BitStrings support substring extraction and bit pattern matching. +

        BitSet

        +

        +BitSets are objects that contain logically infinite sets of nonnegative +integers. Representational details are discussed in the Representation +chapter. Because they are logically infinite, all BitSets possess a +trailing, infinitely replicated 0 or 1 bit, called the "virtual bit", and +indicated via 0* or 1*. +

        +BitSet32 and BitSet256 have they same properties, except they are +of fixed length, and thus have no virtual bit. +

        +BitSets may be constructed as follows: +

        +

        +

        +

        BitSet a; +
        declares an empty BitSet. +

        +

        BitSet a = atoBitSet("001000"); +
        sets a to the BitSet 0010*, reading left-to-right. The "0*" +indicates that the set ends with an infinite number of zero +(clear) bits. +

        +

        BitSet a = atoBitSet("00101*"); +
        sets a to the BitSet 00101*, where "1*" means that the set ends +with an infinite number of one (set) bits. +

        +

        BitSet a = longtoBitSet((long)23); +
        sets a to the BitSet 111010*, the binary representation of decimal 23. +

        +

        BitSet a = utoBitSet((unsigned)23); +
        sets a to the BitSet 111010*, the binary representation of decimal 23. +

        +

        +

        +The following functions and operators are provided (Assume the +declaration of BitSets a = 0011010*, b = 101101*, throughout, as +examples). +

        +

        +

        +

        ~a +
        returns the complement of a, or 1100101* in this case. +

        +

        a.complement() +
        sets a to ~a. +

        +

        a & b; a &= b; +
        returns a intersected with b, or 0011010*. +

        +

        a | b; a |= b; +
        returns a unioned with b, or 1011111*. +

        +

        a - b; a -= b; +
        returns the set difference of a and b, or 000010*. +

        +

        a ^ b; a ^= b; +
        returns the symmetric difference of a and b, or 1000101*. +

        +

        a.empty() +
        returns true if a is an empty set. +

        +

        a == b; +
        returns true if a and b contain the same set. +

        +

        a <= b; +
        returns true if a is a subset of b. +

        +

        a < b; +
        returns true if a is a proper subset of b; +

        +

        a != b; a >= b; a > b; +
        are the converses of the above. +

        +

        a.set(7) +
        sets the 7th (counting from 0) bit of a, setting a to 001111010* +

        +

        a.clear(2) +
        clears the 2nd bit bit of a, setting a to 00011110* +

        +

        a.clear() +
        clears all bits of a; +

        +

        a.set() +
        sets all bits of a; +

        +

        a.invert(0) +
        complements the 0th bit of a, setting a to 10011110* +

        +

        a.set(0,1) +
        sets the 0th through 1st bits of a, setting a to 110111110* +The two-argument versions of clear and invert are similar. +

        +

        a.test(3) +
        returns true if the 3rd bit of a is set. +

        +

        a.test(3, 5) +
        returns true if any of bits 3 through 5 are set. +

        +

        int i = a[3]; a[3] = 0; +
        The subscript operator allows bits to be inspected and changed +via standard subscript semantics, using a friend class BitSetBit. +The use of the subscript operator a[i] rather than a.test(i) +requires somewhat greater overhead. +

        +

        a.first(1) or a.first() +
        returns the index of the first set bit of a (2 in this case), +or -1 if no bits are set. +

        +

        a.first(0) +
        returns the index of the first clear bit of a (0 in this case), +or -1 if no bits are clear. +

        +

        a.next(2, 1) or a.next(2) +
        returns the index of the next bit after position 2 that is set (3 +in this case) or -1. first and next may be used as +iterators, as in +for (int i = a.first(); i >= 0; i = a.next(i)).... +

        +

        a.last(1) +
        returns the index of the rightmost set bit, or -1 if there or no set +bits or all set bits. +

        +

        a.prev(3, 0) +
        returns the index of the previous clear bit before position 3. +

        +

        a.count(1) +
        returns the number of set bits in a, or -1 if there are +an infinite number. +

        +

        a.virtual_bit() +
        returns the trailing (infinitely replicated) bit of a. +

        +

        a = atoBitSet("ababX", 'a', 'b', 'X'); +
        converts the char* string into a bitset, with 'a' denoting false, +'b' denoting true, and 'X' denoting infinite replication. +

        +

        a.printon(cout, '-', '.', 0) +
        prints a to cout represented with +'-' for falses, '.' for trues, and no replication marker. +

        +

        cout << a +
        prints a to cout (representing lases by 'f', +trues by 't', and using '*' as the replication marker). +

        +

        diff(x, y, z) +
        A faster way to say z = x - y. +

        +

        and(x, y, z) +
        A faster way to say z = x & y. +

        +

        or(x, y, z) +
        A faster way to say z = x | y. +

        +

        xor(x, y, z) +
        A faster way to say z = x ^ y. +

        +

        complement(x, z) +
        A faster way to say z = ~x. +

        +

        +

        +

        BitString

        +

        +BitStrings are objects that contain arbitrary-length strings of +zeroes and ones. BitStrings possess some features that make them +behave like sets, and others that behave as strings. They are +useful in applications (such as signature-based algorithms) where +both capabilities are needed. Representational details are +discussed in the Representation chapter. Most capabilities are +exact analogs of those supported in the BitSet and String +classes. A BitSubString is used with substring operations along +the same lines as the String SubString class. A BitPattern class +is used for masked bit pattern searching. +

        +Only a default constructor is supported. The declaration +BitString a; initializes a to be an empty BitString. +BitStrings may often be initialized via atoBitString +and longtoBitString. +

        +Set operations ( ~, complement, &, &=, |, |=, -, ^, ^=) +behave just as the BitSet versions, except that there is no +"virtual bit": complementing complements only those bits in the +BitString, and all binary operations across unequal length +BitStrings assume a virtual bit of zero. The & operation +returns a BitString with a length equal to the minimum length of +the operands, and |, ^ return one with length of the +maximum. +

        +Set-based relational operations (==, !=, <=, <, >=, >) +follow the same rules. A string-like lexicographic comparison +function, lcompare, tests the lexicographic relation between +two BitStrings. For example, lcompare(1100, 0101) returns 1, +since the first BitString starts with 1 and the second with 0. +

        +Individual bit setting, testing, and iterator operations +(set, clear, invert, test, first, next, last, prev) +are also like those for BitSets. BitStrings are automatically +expanded when setting bits at positions greater than their +current length. +

        +The string-based capabilities are just as those for class String. +BitStrings may be concatenated (+, +=), searched +(index, contains, matches), and extracted into +BitSubStrings (before, at, after) which may be assigned and +otherwise manipulated. Other string-based utility functions +(reverse, common_prefix, common_suffix) are also provided. +These have the same capabilities and descriptions as those +for Strings. +

        +String-oriented operations can also be performed with a mask via +class BitPattern. BitPatterns consist of two BitStrings, a +pattern and a mask. On searching and matching, bits in the pattern +that correspond to 0 bits in the mask are ignored. (The mask may +be shorter than the pattern, in which case trailing mask bits are +assumed to be 0). The pattern and mask are both public variables, +and may be individually subjected to other bit operations. +

        +Converting to char* and printing ((atoBitString, +atoBitPattern, printon, ostream <<)) are also as in BitSets, +except that no virtual bit is used, and an 'X' in a BitPattern means +that the pattern bit is masked out. +

        +The following features are unique to BitStrings. +

        +Assume declarations of BitString a = atoBitString("01010110") and b = +atoBitSTring("1101"). +

        +

        +

        +

        a = b + c; +
        Sets a to the concatenation of b and c; +

        +

        a = b + 0; a = b + 1; +
        sets a to b, appended with a zero (one). +

        +

        a += b; +
        appends b to a; +

        +

        a += 0; a += 1; +
        appends a zero (one) to a. +

        +

        a << 2; a <<= 2 +
        return a with 2 zeros prepended, setting a to 0001010110. (Note +the necessary confusion of << and >> operators. For consistency +with the integer versions, << shifts low bits to high, even though +they are printed low bits first.) +

        +

        a >> 3; a >>= 3 +
        return a with the first 3 bits deleted, setting a to 10110. +

        +

        a.left_trim(0) +
        deletes all 0 bits on the left of a, setting a to 1010110. +

        +

        a.right_trim(0) +
        deletes all trailing 0 bits of a, setting a to 0101011. +

        +

        cat(x, y, z) +
        A faster way to say z = x + y. +

        +

        diff(x, y, z) +
        A faster way to say z = x - y. +

        +

        and(x, y, z) +
        A faster way to say z = x & y. +

        +

        or(x, y, z) +
        A faster way to say z = x | y. +

        +

        xor(x, y, z) +
        A faster way to say z = x ^ y. +

        +

        lshift(x, y, z) +
        A faster way to say z = x << y. +

        +

        rshift(x, y, z) +
        A faster way to say z = x >> y. +

        +

        complement(x, z) +
        A faster way to say z = ~x. +

        +

        +

        +

        Random Number Generators and related classes

        +

        +The two classes RNG and Random are used together to +generate a variety of random number distributions. A distinction must +be made between random number generators, implemented by class +RNG, and random number distributions. A random number +generator produces a series of randomly ordered bits. These bits can be +used directly, or cast to other representations, such as a floating +point value. A random number generator should produce a uniform +distribution. A random number distribution, on the other hand, uses the +randomly generated bits of a generator to produce numbers from a +distribution with specific properties. Each instance of Random +uses an instance of class RNG to provide the raw, uniform +distribution used to produce the specific distribution. Several +instances of Random classes can share the same instance of +RNG, or each instance can use its own copy. +

        +

        RNG

        +

        +Random distributions are constructed from members of class RNG, +the actual random number generators. The RNG class contains no +data; it only serves to define the interface to random number +generators. The RNG::asLong member returns an unsigned long +(typically 32 bits) of random bits. Applications that require a number +of random bits can use this directly. More often, these random bits are +transformed to a uniform random number: +

        +

        +    //
+    // Return random bits converted to either a float or a double
+    //
+    float asFloat();
+    double asDouble();
+};
+
        +

        +using either asFloat or asDouble. It is intended that +asFloat and asDouble return differing precisions; +typically, asDouble will draw two random longwords and transform +them into a legal double, while asFloat will draw a single +longword and transform it into a legal float. These members are +used by subclasses of the Random class to implement a variety of +random number distributions. +

        +

        ACG

        +

        +Class ACG is a variant of a Linear Congruential Generator +(Algorithm M) described in Knuth, Art of Computer Programming, Vol +III. This result is permuted with a Fibonacci Additive Congruential +Generator to get good independence between samples. This is a very high +quality random number generator, although it requires a fair amount of +memory for each instance of the generator. +

        +The ACG::ACG constructor takes two parameters: the seed and the +size. The seed is any number to be used as an initial seed. The +performance of the generator depends on having a distribution of bits +through the seed. If you choose a number in the range of 0 to 31, a +seed with more bits is chosen. Other values are deterministically +modified to give a better distribution of bits. This provides a good +random number generator while still allowing a sequence to be repeated +given the same initial seed. +

        +The size parameter determines the size of two tables used in the +generator. The first table is used in the Additive Generator; see the +algorithm in Knuth for more information. In general, this table is +size longwords long. The default value, used in the algorithm in +Knuth, gives a table of 220 bytes. The table size affects the period of +the generators; smaller values give shorter periods and larger tables +give longer periods. The smallest table size is 7 longwords, and the +longest is 98 longwords. The size parameter also determines the +size of the table used for the Linear Congruential Generator. This value +is chosen implicitly based on the size of the Additive Congruential +Generator table. It is two powers of two larger than the power of two +that is larger than size. For example, if size is 7, the +ACG table is 7 longwords and the LCG table is 128 longwords. Thus, the +default size (55) requires 55 + 256 longwords, or 1244 bytes. The +largest table requires 2440 bytes and the smallest table requires 100 +bytes. Applications that require a large number of generators or +applications that aren't so fussy about the quality of the generator may +elect to use the MLCG generator. +

        +

        MLCG

        +

        +The MLCG class implements a Multiplicative Linear +Congruential Generator. In particular, it is an implementation of the +double MLCG described in "Efficient and Portable Combined Random +Number Generators" by Pierre L'Ecuyer, appearing in +Communications of the ACM, Vol. 31. No. 6. This generator has a +fairly long period, and has been statistically analyzed to show that it +gives good inter-sample independence. +

        +The MLCG::MLCG constructor has two parameters, both of which are +seeds for the generator. As in the MLCG generator, both seeds are +modified to give a "better" distribution of seed digits. Thus, you can +safely use values such as `0' or `1' for the seeds. The MLCG +generator used much less state than the ACG generator; only two +longwords (8 bytes) are needed for each generator. +

        +

        Random

        +

        +A random number generator may be declared by first declaring a +RNG and then a Random. For example, ACG gen(10, 20); +NegativeExpntl rnd (1.0, &gen); declares an additive congruential +generator with seed 10 and table size 20, that is used to generate +exponentially distributed values with mean of 1.0. +

        +The virtual member Random::operator() is the common way of +extracting a random number from a particular distribution. The base +class, Random does not implement operator(). This is +performed by each of the subclasses. Thus, given the above declaration +of rnd, new random values may be obtained via, for example, +double next_exp_rand = rnd(); Currently, the following subclasses +are provided. +

        +

        Binomial

        +

        +The binomial distribution models successfully drawing items from +a pool. The first parameter to the constructor, n, is the +number of items in the pool, and the second parameter, u, +is the probability of each item being successfully drawn. The +member asDouble returns the number of samples drawn from +the pool. Although it is not checked, it is assumed that +n>0 and 0 <= u <= 1. The remaining members allow +you to read and set the parameters. +

        +

        Erlang

        +

        +The Erlang class implements an Erlang distribution with +mean mean and variance variance. +

        +

        Geometric

        +

        +The Geometric class implements a discrete geometric +distribution. The first parameter to the constructor, +mean, is the mean of the distribution. Although it is not +checked, it is assumed that 0 <= mean <= 1. +Geometric() returns the number of uniform random samples +that were drawn before the sample was larger than mean. +This quantity is always greater than zero. +

        +

        HyperGeometric

        +

        +The HyperGeometric class implements the hypergeometric +distribution. The first parameter to the constructor, +mean, is the mean and the second, variance, is the +variance. The remaining members allow you to inspect and change +the mean and variance. +

        +

        NegativeExpntl

        +

        +The NegativeExpntl class implements the negative +exponential distribution. The first parameter to the constructor +is the mean. The remaining members allow you to inspect and +change the mean. +

        +

        Normal

        +

        +The Normalclass implements the normal distribution. The +first parameter to the constructor, mean, is the mean and +the second, variance, is the variance. The remaining +members allow you to inspect and change the mean and variance. +The LogNormal class is a subclass of Normal. +

        +

        LogNormal

        +

        +The LogNormalclass implements the logarithmic normal +distribution. The first parameter to the constructor, +mean, is the mean and the second, variance, is the +variance. The remaining members allow you to inspect and change +the mean and variance. The LogNormal class is a subclass +of Normal. +

        +

        Poisson

        +

        +The Poisson class implements the poisson distribution. +The first parameter to the constructor is the mean. The +remaining members allow you to inspect and change the mean. +

        +

        DiscreteUniform

        +

        +The DiscreteUniform class implements a uniform random variable over +the closed interval ranging from [low..high]. The first parameter +to the constructor is low, and the second is high, although +the order of these may be reversed. The remaining members allow you to +inspect and change low and high. +

        +

        Uniform

        +

        +The Uniform class implements a uniform random variable over the +open interval ranging from [low..high). The first parameter to +the constructor is low, and the second is high, although +the order of these may be reversed. The remaining members allow you to +inspect and change low and high.

        +

        Weibull

        +

        +The Weibull class implements a weibull distribution with +parameters alpha and beta. The first parameter to +the class constructor is alpha, and the second parameter +is beta. The remaining members allow you to inspect and +change alpha and beta. +

        +

        RandomInteger

        +

        +The RandomInteger class is not a subclass of Random, +but a stand-alone integer-oriented class that is dependent on the +RNG classes. RandomInteger returns random integers uniformly from +the closed interval [low..high]. The first parameter to the +constructor is low, and the second is high, although +both are optional. The last argument is always a generator. +Additional members allow you to inspect and change low and +high. Random integers are generated using asInt() or +asLong(). Operator syntax (()) is also available as a +shorthand for asLong(). Because RandomInteger is often +used in simulations for which uniform random integers are desired over +a variety of ranges, asLong() and asInt have high +as an optional argument. Using this optional argument produces a +single value from the new range, but does not change the default +range. +

        +

        Data Collection

        +Libg++ currently provides two classes for data collection +and analysis of the collected data. +

        +

        SampleStatistic

        +

        +Class SampleStatistic provides a means of accumulating +samples of double values and providing common sample statistics. +

        +Assume declaration of double x. +

        +

        +

        +

        SampleStatistic a; +
        declares and initializes a. +

        +

        a.reset(); +
        re-initializes a. +

        +

        a += x; +
        adds sample x. +

        +

        int n = a.samples(); +
        returns the number of samples. +

        +

        x = a.mean; +
        returns the means of the samples. +

        +

        x = a.var() +
        returns the sample variance of the samples. +

        SampleHistogram

        +

        +Class SampleHistogram is a derived class of +SampleStatistic that supports collection and display of samples +in bucketed intervals. It supports the following in addition to +SampleStatisic operations. +

        +

        +

        +

        SampleHistogram h(double lo, double hi, double width); +
        declares and initializes h to have buckets of size width from lo to hi. +If the optional argument width is not specified, 10 buckets are +created. The first bucket and also holds samples less than lo, +and the last one holds samples greater than hi. +

        +

        int n = h.similarSamples(x) +
        returns the number of samples in the same bucket as x. +

        +

        int n = h.inBucket(int i) +

        +

        +

        Curses-based classes

        +

        +The CursesWindow class is a repackaging of standard +curses library features into a class. It relies on `curses.h'. +

        +The supplied `curses.h' is a fairly conservative declaration +of curses library features, and does not include features like +"screen" or X-window support. It is, for the most part, an +adaptation, rather than an improvement of C-based `curses.h' +files. The only substantive changes are the declarations of +many functions as inline functions rather than macros, which +was done solely to allow overloading. +

        +The CursesWindow class encapsulates curses window functions +within a class. Only those functions that control windows are included: +Terminal control functions and macros like cbreak are not part +of the class. All CursesWindows member functions have names +identical to the corresponding curses library functions, except that the +"w" prefix is generally dropped. Descriptions of these functions may +be found in your local curses library documentation. +

        +A CursesWindow may be declared via +

        +

        +

        +

        CursesWindow w(WINDOW* win) +
        attaches w to the existing WINDOW* win. This is constructor is normally +used only in the following special case. +

        +

        CursesWindow w(stdscr) +
        attaches w to the default curses library standard screen window. +

        +

        CursesWindow w(int lines, int cols, int begin_y, int begin_x) +
        attaches to an allocated curses window with the indicated size and +screen position. +

        +

        CursesWindow sub(CursesWindow& w,int l,int c,int by,int bx,char ar='a') +
        attaches to a subwindow of w created via the curses `subwin' command. +If ar is sent as `r', the origin (by, bx) is relative to the parent +window, else it is absolute. +

        +

        +

        +The class maintains a static counter that is used in order to +automatically call the curses library initscr and endscr +functions at the proper times. These need not, and should not be +called "manually". +

        +CursesWindows maintain a tree of their subwindows. Upon +destruction of a CursesWindow, all of their subwindows are +also invalidated if they had not previously been destroyed. +

        +It is possible to traverse trees of subwindows via the following +member functions +

        +

        +

        +

        CursesWindow* w.parent() +
        returns a pointer to the parent of the subwindow, or 0 if there is none. +

        +

        CursesWindow* w.child() +
        returns the first child subwindow of the window, or 0 if there is none. +

        +

        CursesWindow* w.sibling() +
        returns the next sibling of the subwindow, or 0 if there is none. +

        +

        +

        +For example, to call some function visit for all subwindows +of a window, you could write +

        +

        +
+void traverse(CursesWindow& w)
+{
+  visit(w);
+  if (w.child() != 0) traverse(*w.child);
+  if (w.sibling() != 0) traverse(*w.sibling);
+}
+
+
        + +

        List classes

        +

        +The files `g++-include/List.hP' and `g++-include/List.ccP' +provide pseudo-generic Lisp-type List classes. These lists are homogeneous +lists, more similar to lists in statically typed functional languages like +ML than Lisp, but support operations very similar to those found in Lisp. +Any particular kind of list class may be generated via the genclass +shell command. However, the implementation assumes that the base class +supports an equality operator ==. All equality tests use the +== operator, and are thus equivalent to the use of equal, not +eq in Lisp.

        +All list nodes are created dynamically, and managed via reference counts. +List variables are actually pointers to these list nodes. +Lists may also be traversed via Pixes, as described in the section +describing Pixes. See section Pseudo-indexes +

        +Supported operations are mirrored closely after those in Lisp. Generally, +operations with functional forms are constructive, functional operations, +while member forms (often with the same name) are sometimes +procedural, possibly destructive operations. +

        +As with Lisp, destructive operations are supported. Programmers +are allowed to change head and tail fields in any fashion, creating +circular structures and the like. However, again as with Lisp, some +operations implicitly assume that they are operating on pure lists, and +may enter infinite loops when presented with improper lists. Also, the +reference-counting storage management facility may fail to reclaim +unused circularly-linked nodes. +

        +Several Lisp-like higher order functions are supported (e.g., map). +Typedef declarations for the required functional forms are provided +int the `.h' file. +

        +For purposes of illustration, assume the specification of class +intList. Common Lisp versions of supported operations are shown +in brackets for comparison purposes. +

        +

        +

        intList(); [ nil ] +
        intList() may be used to null terminate a list, as in +intList f(int x) {if (x == 0) return intList(); ... } . +

        +

        +

        +

        Constructive operations

        +

        Linked Lists

        +

        +SLLists provide pseudo-generic singly linked lists. DLLists provide +doubly linked lists. The lists are designed for the simple maintenance +of elements in a linked structure, and do not provide the more extensive +operations (or node-sharing) of class List. They behave similarly +to the slist and similar classes described by Stroustrup.

        +All list nodes are created dynamically. Assignment is performed via +copying. +

        +Class DLList supports all SLList operations, plus +additional operations described below. +

        +For purposes of illustration, assume the specification of class +intSLList. In addition to the operations listed here, +SLLists support traversal via Pixes. See section Pseudo-indexes +

        +

        +

        +

        intSLList a; +
        Declares a to be an empty list. +

        +

        intSLList b = a; +
        Sets b to an element-by-element copy of a. +

        +

        a.empty() +
        returns true if a contains no elements +

        +

        a.length(); +
        returns the number of elements in a. +

        +

        a.prepend(x); +
        places x at the front of the list. +

        +

        a.append(x); +
        places x at the end of the list. +

        +

        a.join(b) +
        places all nodes from b to the end of a, simultaneously destroying b. +

        +

        x = a.front() +
        returns a reference to the item stored at the head of the list, +or triggers an error if the list is empty. +

        +

        a.rear() +
        returns a reference to the rear of the list, or triggers an error if the +list is empty. +

        +

        x = a.remove_front() +
        deletes and returns the item stored at the head of the list. +

        +

        a.del_front() +
        deletes the first element, without returning it. +

        +

        a.clear() +
        deletes all items from the list. +

        +

        a.ins_after(Pix i, item); +
        inserts item after position i. If i is null, insertion is at the front. +

        +

        a.del_after(Pix i); +
        deletes the element following i. If i is 0, the first item is deleted. +

        +

        +

        +

        Doubly linked lists

        +

        +Class DLList supports the following additional operations, +as well as backward traversal via Pixes. +

        +

        +

        +

        x = a.remove_rear(); +
        deletes and returns the item stored at the rear of the list. +

        +

        a.del_rear(); +
        deletes the last element, without returning it. +

        +

        a.ins_before(Pix i, x) +
        inserts x before the i. +

        +

        a.del(Pix& iint dir = 1) +
        deletes the item at the current position, then advances forward +if dir is positive, else backward. +

        +

        +

        +

        Vector classes

        +

        +The files `g++-include/Vec.ccP' and `g++-include/AVec.ccP' +provide pseudo-generic standard array-based vector operations. The +corresponding header files are `g++-include/Vec.hP' and +`g++-include/AVec.hP'. Class Vec provides operations +suitable for any base class that includes an equality operator. Subclass +AVec provides additional arithmetic operations suitable for base +classes that include the full complement of arithmetic operators. +

        +Vecs are constructed and assigned by copying. Thus, they should +normally be passed by reference in applications programs. +

        +Several mapping functions are provided that allow programmers to +specify operations on vectors as a whole. +

        +For illustrative purposes assume that classes intVec and +intAVec have been generated via genclass. +

        +

        Constructors and assignment

        +

        +

        +
        intVec a; +
        declares a to be an empty vector. Its size may be changed via resize. +

        +

        intVec a(10); +
        declares a to be an uninitialized vector of ten elements (numbered 0-9). +

        +

        intVec b(6, 0); +
        declares b to be a vector of six elements, all initialized to zero. Any +value can be used as the initial fill argument. +

        +

        a = b; +
        Copies b to a. a is resized to be the same as b. +

        +

        a = b.at(2, 4) +
        constructs a from the 4 elements of b starting at b[2]. +
        +

        +Assume declarations of intVec a, b, c and int i, x in +the following. +

        +

        Status and access

        +

        +

        +
        a.capacity(); +
        returns the number of elements that can be held in a. +

        +

        a.resize(20); +
        sets a's length to 20. All elements are unchanged, except that if +the new size is smaller than the original, than trailing elements +are deleted, and if greater, trailing elements are uninitialized. +

        +

        a[i]; +
        returns a reference to the i'th element of a, or produces an error +if i is out of range. +

        +

        a.elem(i) +
        returns a reference to the i'th element of a. Unlike the [] operator, +i is not checked to ensure that it is within range. +

        +

        a == b; +
        returns true if a and b contain the same elements in the same order. +

        +

        a != b; +
        is the converse of a == b. +
        +

        +

        Constructive operations

        +

        +

        +
        c = concat(a, b); +
        sets c to the new vector constructed from all of the elements of +a followed by all of b. +

        +

        c = map(f, a); +
        sets c to the new vector constructed by applying int function f(int) +to each element of a. +

        +

        +

        c = combine(f, a, b); +
        sets c to the new vector constructed by applying int function f(int, int) +to successive pairs of a and b. The result has length the shorter of +a and b. +

        Destructive operations

        +

        +

        +
        a.reverse(); +
        reverses a in-place. +

        +

        a.sort(f) +
        sorts a in-place using comparison function f. The sorting method is a +variation of the quicksort functions supplied with GNU emacs. +

        +

        a.fill(0, 4, 2) +
        fills the 2 elements starting at a[4] with zero. +

        +

        +

        +

        a.apply(f) +
        applies function f to each element in a. +

        +

        x = a.reduce(f, base) +
        accumulates the results of applying function f to successive elements +of a starting with base. +

        +

        a.index(int targ); +
        returns the index of the leftmost occurrence of the target, or -1, +if it does not occur. +

        +

        a.error(char* msg) +
        invokes the error handler. The default version prints the error message, +then aborts. +
        +

        +

        AVec operations.

        +

        +AVecs provide additional arithmetic operations. All vector-by-vector +operators generate an error if the vectors are not the same length. The +following operations are provided, for AVecs a, b and +base element (scalar) s. +

        +

        +
        a = b; +
        Copies b to a. a and b must be the same size. +

        +

        a = s; +
        fills all elements of a with the value s. a is not resized. +

        +

        a + s; a - s; a * s; a / s +
        adds, subtracts, multiplies, or divides each element of a with the scalar. +

        +

        a += s; a -= s; a *= s; a /= s; +
        adds, subtracts, multiplies, or divides the scalar into a. +

        +

        a + b; a - b; product(a, b), quotient(a, b) +
        adds, subtracts, multiplies, or divides corresponding elements of a and b. +

        +

        a += b; a -= b; a.product(b); a.quotient(b); +
        adds, subtracts, multiplies, or divides corresponding elements of b into a. +

        +

        s = a * b; +
        returns the inner (dot) product of a and b. +

        +

        x = a.sum(); +
        returns the sum of elements of a. +

        +

        x = a.sumsq(); +
        returns the sum of squared elements of a. +

        +

        x = a.min(); +
        returns the minimum element of a. +

        +

        x = a.max(); +
        returns the maximum element of a. +

        +

        i = a.min_index(); +
        returns the index of the minimum element of a. +

        +

        i = a.max_index(); +
        returns the index of the maximum element of a. +

        +Note that it is possible to apply vector versions other arithmetic +operators via the mapping functions. For example, to set vector b +to the cosines of doubleVec a, use b = map(cos, a);. +This is often more efficient than performing the operations +in an element-by-element fashion. +

        +

        +

        Plex classes

        +

        +A "Plex" is a kind of array with the following properties: +

        +

          +
        • +Plexes may have arbitrary upper and lower index bounds. For example +a Plex may be declared to run from indices -10 .. 10. +

          +

        • +Plexes may be dynamically expanded at both the lower and upper bounds +of the array in steps of one element. +

          +

        • +Only elements that have been specifically initialized or added may +be accessed. +

          +

        • +Elements may be accessed via indices. Indices are always checked for +validity at run time. Plexes may be traversed via simple variations of +standard array indexing loops. +

          +

        • +Plex elements may be accessed and traversed via Pixes. +

          +

        • +Plex-to-Plex assignment and related operations on entire Plexes +are supported. +

          +

        • +Plex classes contain methods to help programmers check the validity +of indexing and pointer operations. +

          +

        • +Plexes form "natural" base classes for many restricted-access data +structures relying on logically contiguous indices, such as array-based +stacks and queues. +

          +

        • +Plexes are implemented as pseudo-generic classes, and must be generated +via the genclass utility. +
        +

        +Four subclasses of Plexes are supported: A FPlex is a Plex that +may only grow or shrink within declared bounds; an XPlex may +dynamically grow or shrink without bounds; an RPlex is the +same as an XPlex but better supports indexing with poor +locality of reference; a MPlex may grow +or shrink, and additionally allows the logical deletion and restoration +of elements. Because these classes are virtual subclasses of the +"abstract" class Plex, it is possible to write user code +such as void f(Plex& a) ... that operates on any kind of +Plex. However, as with nearly any virtual class, specifying the +particular Plex class being used results in more efficient code. +

        +Plexes are implemented as a linked list of IChunks. Each chunk +contains a part of the array. Chunk sizes may be specified within Plex +constructors. Default versions also exist, that use a #define'd +default. Plexes grow by filling unused space in existing chunks, if +possible, else, except for FPlexes, by adding another chunk. Whenever +Plexes grow by a new chunk, the default element constructors (i.e., +those which take no arguments) for all chunk elements are called at +once. When Plexes shrink, destructors for the elements are not called +until an entire chunk is freed. For this reason, Plexes (like C++ +arrays) should only be used for elements with default constructors and +destructors that have no side effects. +

        +Plexes may be indexed and used like arrays, although traversal +syntax is slightly different. Even though Plexes maintain elements +in lists of chunks, they are implemented so that iteration and +other constructs that maintain locality of reference require very +little overhead over that for simple array traversal +Pix-based traversal is also supported. For example, for a plex, p, +of ints, the following traversal methods could be used. +

        +

        +for (int i = p.low(); i < p.fence(); p.next(i)) use(p[i]);
+for (int i = p.high(); i > p.ecnef(); p.prev(i)) use(p[i]);
+for (Pix t = p.first(); t != 0; p.next(t)) use(p(i));
+for (Pix t = p.last(); t != 0; p.prev(t)) use(p(i));
+
        +

        +Except for MPlexes, simply using ++i and --i works just as +well as p.next(i) and p.prev(i) when traversing by index. +Index-based traversal is generally a bit faster than Pix-based +traversal. +

        +XPlexes and MPlexes are less than optimal for applications +in which widely scattered elements are indexed, as might occur when +using Plexes as hash tables or "manually" allocated linked lists. +In such applications, RPlexes are often preferable. RPlexes +use a secondary chunk index table that requires slightly greater, +but entirely uniform overhead per index operation. +

        +Even though they may grow in either direction, Plexes are normally +constructed so that their "natural" growth direction is upwards, +in that default chunk construction leaves free space, if present, +at the end of the plex. However, if the chunksize arguments to +constructors are negative, they leave space at the beginning. +

        +All versions of Plexes support the following basic capabilities. +(letting Plex stand for the type name constructed via the +genclass utility (e.g., intPlex, doublePlex)). Assume +declarations of Plex p, q, int i, j, base element +x, and Pix pix. +

        +

        +

        +

        Plex p; +
        Declares p to be an initially zero-sized Plex with low index of zero, +and the default chunk size. For FPlexes, chunk sizes represent maximum +sizes. +

        +

        Plex p(int size); +
        Declares p to be an initially zero-sized Plex with low index of zero, +and the indicated chunk size. If size is negative, then the Plex +is created with free space at the beginning of the Plex, +allowing more efficient add_low() operations. Otherwise, it +leaves space at the end. +

        +

        Plex p(int low, int size); +
        Declares p to be an initially zero-sized Plex with low index of low, +and the indicated chunk size. +

        +

        Plex p(int low, int high, Base initval, int size = 0); +
        Declares p to be a Plex with indices from low to high, initially +filled with initval, and the indicated chunk size if specified, +else the default or (high - low + 1), whichever is greater. +

        +

        Plex q(p); +
        Declares q to be a copy of p. +

        +

        p = q; +
        Copies Plex q into p, deleting its previous contents. +

        +

        p.length() +
        Returns the number of elements in the Plex. +

        +

        p.empty() +
        Returns true if Plex p contains no elements. +

        +

        p.full() +
        Returns true if Plex p cannot be expanded. This always returns +false for XPlexes and MPlexes. +

        +

        p[i] +
        Returns a reference to the i'th element of p. An exception (error) occurs +if i is not a valid index. +

        +

        p.valid(i) +
        Returns true if i is a valid index into Plex p. +

        +

        p.low(); p.high(); +
        Return the minimum (maximum) valid index of the Plex, or the high (low) +fence if the plex is empty. +

        +

        p.ecnef(); p.fence(); +
        Return the index one position past the minimum (maximum) valid index. +

        +

        p.next(i); i = p.prev(i); +
        Set i to the next (previous) index. This index may not be within bounds. +

        +

        p(pix) +
        returns a reference to the item at Pix pix. +

        +

        pix = p.first(); pix = p.last(); +
        Return the minimum (maximum) valid Pix of the Plex, or 0 +if the plex is empty. +

        +

        p.next(pix); p.prev(pix); +
        set pix to the next (previous) Pix, or 0 if there is none. +

        +

        p.owns(pix) +
        Returns true if the Plex contains the element associated with pix. +

        +

        p.Pix_to_index(pix) +
        If pix is a valid Pix to an element of the Plex, +returns its corresponding index, else raises an exception. +

        +

        ptr = p.index_to_Pix(i) +
        if i is a valid index, returns a the corresponding Pix. +

        +

        p.low_element(); p.high_element(); +
        Return a reference to the element at the minimum (maximum) valid index. +An exception occurs if the Plex is empty. +

        +

        p.can_add_low(); p.can_add_high(); +
        Returns true if the plex can be extended one element downward (upward). +These always return true for XPlex and MPlex. +

        +

        j = p.add_low(x); j = p.add_high(x); +
        Extend the Plex by one element downward (upward). The new minimum +(maximum) index is returned. +

        +

        j = p.del_low(); j = p.del_high() +
        Shrink the Plex by one element on the low (high) end. The new +minimum (maximum) element is returned. An exception occurs if the +Plex is empty. +

        +

        p.append(q); +
        Append all of Plex q to the high side of p. +

        +

        p.prepend(q); +
        Prepend all of q to the low side of p. +

        +

        p.clear() +
        Delete all elements, resetting p to a zero-sized Plex. +

        +

        p.reset_low(i); +
        Resets p to be indexed starting at low() = i. For example. +if p were initially declared via Plex p(0, 10, 0), +and then re-indexed via p.reset_low(5), +it could then be indexed from indices 5 .. 14. +

        +

        p.fill(x) +
        sets all p[i] to x. +

        +

        p.fill(x, lo, hi) +
        sets all of p[i] from lo to hi, inclusive, to x. +

        +

        p.reverse() +
        reverses p in-place. +

        +

        p.chunk_size() +
        returns the chunk size used for the plex. +

        +

        p.error(const char * msg) +
        calls the resettable error handler. +

        +

        +

        +MPlexes are plexes with bitmaps that allow items to be logically +deleted and restored. They behave like other plexes, but +also support the following additional and modified capabilities: +

        +

        +

        +

        p.del_index(i); p.del_Pix(pix) +
        logically deletes p[i] (p(pix)). After deletion, attempts to access p[i] +generate a error. Indexing via low(), high(), prev(), +and next() skip the element. Deleting an element never changes the +logical bounds of the plex. +

        +

        p.undel_index(i); p.undel_Pix(pix) +
        logically undeletes p[i] (p(pix)). +

        +

        p.del_low(); p.del_high() +
        Delete the lowest (highest) undeleted element, resetting the +logical bounds of the plex to the next lowest (highest) undeleted +index. Thus, MPlex del_low() and del_high() may shrink the bounds +of the plex by more than one index. +

        +

        p.adjust_bounds() +
        Resets the low and high bounds of the Plex to the indexes of +the lowest and highest actual undeleted elements. +

        +

        int i = p.add(x) +
        Adds x in an unused index, if possible, else performs add_high. +

        +

        p.count() +
        returns the number of valid (undeleted) elements. +

        +

        p.available() +
        returns the number of available (deleted) indices. +

        +

        int i = p.unused_index() +
        returns the index of some deleted element, if one exists, +else triggers an error. An unused element may be reused via undel. +

        +

        pix = p.unused_Pix() +
        returns the pix of some deleted element, if one exists, else 0. +An unused element may be reused via undel. +

        +

        +

        +

        Stacks

        +

        +Stacks are declared as an "abstract" class. They are currently +implemented in any of three ways. +

        +

        +

        +

        VStack +
        implement fixed sized stacks via arrays. +

        +

        XPStack +
        implement dynamically-sized stacks via XPlexes. +

        +

        SLStack +
        implement dynamically-size stacks via linked lists. +

        +

        +

        +All possess the same capabilities. They differ only in constructors. +VStack constructors require a fixed maximum capacity argument. +XPStack constructors optionally take a chunk size argument. +SLStack constructors take no argument. +

        +Assume the declaration of a base element x. +

        +

        +

        +

        Stack s; or Stack s(int capacity) +
        declares a Stack. +

        +

        s.empty() +
        returns true if stack s is empty. +

        +

        s.full() +
        returns true if stack s is full. XPStacks and SLStacks never become full. +

        +

        s.length() +
        returns the current number of elements in the stack. +

        +

        s.push(x) +
        pushes x on stack s. +

        +

        x = s.pop() +
        pops and returns the top of stack +

        +

        s.top() +
        returns a reference to the top of stack. +

        +

        s.del_top() +
        pops, but does not return the top of stack. When large items are held +on the stack it is often a good idea to use top() to inspect and use +the top of stack, followed by a del_top() +

        +

        s.clear() +
        removes all elements from the stack. +

        +

        +

        +

        Queues

        +

        +Queues are declared as an "abstract" class. They are currently +implemented in any of three ways. +

        +

        +
        VQueue +
        implement fixed sized Queues via arrays. +

        +

        XPQueue +
        implement dynamically-sized Queues via XPlexes. +

        +

        SLQueue +
        implement dynamically-size Queues via linked lists. +
        +

        +All possess the same capabilities; they differ only in constructors. +VQueue constructors require a fixed maximum capacity argument. +XPQueue constructors optionally take a chunk size argument. +SLQueue constructors take no argument. +

        +Assume the declaration of a base element x. +

        +

        +
        Queue q; or Queue q(int capacity); +
        declares a queue. +

        +

        q.empty() +
        returns true if queue q is empty. +

        +

        q.full() +
        returns true if queue q is full. XPQueues and SLQueues are never full. +

        +

        q.length() +
        returns the current number of elements in the queue. +

        +

        q.enq(x) +
        enqueues x on queue q. +

        +

        x = q.deq() +
        dequeues and returns the front of queue +

        +

        q.front() +
        returns a reference to the front of queue. +

        +

        q.del_front() +
        dequeues, but does not return the front of queue +

        +

        q.clear() +
        removes all elements from the queue. +
        +

        +

        Double ended Queues

        +

        +Deques are declared as an "abstract" class. They are currently +implemented in two ways. +

        +

        +

        +

        XPDeque +
        implement dynamically-sized Deques via XPlexes. +

        +

        DLDeque +
        implement dynamically-size Deques via linked lists. +

        +

        +

        +All possess the same capabilities. They differ only in constructors. +XPDeque constructors optionally take a chunk size argument. +DLDeque constructors take no argument. +

        +Double-ended queues support both stack-like and queue-like capabilities: +

        +Assume the declaration of a base element x. +

        +

        +

        +

        Deque d; or Deque d(int initial_capacity) +
        declares a deque. +

        +

        d.empty() +
        returns true if deque d is empty. +

        +

        d.full() +
        returns true if deque d is full. +Always returns false in current implementations. +

        +

        d.length() +
        returns the current number of elements in the deque. +

        +

        d.enq(x) +
        inserts x at the rear of deque d. +

        +

        d.push(x) +
        inserts x at the front of deque d. +

        +

        x = d.deq() +
        dequeues and returns the front of deque +

        +

        d.front() +
        returns a reference to the front of deque. +

        +

        d.rear() +
        returns a reference to the rear of the deque. +

        +

        d.del_front() +
        deletes, but does not return the front of deque +

        +

        d.del_rear() +
        deletes, but does not return the rear of the deque. +

        +

        d.clear() +
        removes all elements from the deque. +

        +

        +

        +

        Priority Queue class prototypes.

        +

        +Priority queues maintain collections of objects arranged for fast +access to the least element. +

        +Several prototype implementations of priority queues are supported. +

        +

        +

        +

        XPPQs +
        implement 2-ary heaps via XPlexes. +

        +

        SplayPQs +
        implement PQs via Sleator and Tarjan's (JACM 1985) +splay trees. The algorithms use a version of "simple top-down +splaying" (described on page 669 of the article). The simple-splay +mechanism for priority queue functions is loosely based on the one used +by D. Jones in the C splay tree functions available from volume 14 of +the uunet.uu.net archives. +

        +

        PHPQs +
        implement pairing heaps (as described by Fredman and +Sedgewick in Algorithmica, Vol 1, p111-129). Storage for heap elements +is managed via an internal freelist technique. The constructor allows an +initial capacity estimate for freelist space. The storage is automatically +expanded if necessary to hold new items. The deletion technique is a fast +"lazy deletion" strategy that marks items as deleted, without reclaiming +space until the items come to the top of the heap. +

        +

        +

        +All PQ classes support the following operations, for some PQ class +Heap, instance h, Pix ind, and base class +variable x. +

        +

        +

        +

        h.empty() +
        returns true if there are no elements in the PQ. +

        +

        h.length() +
        returns the number of elements in h. +

        +

        ind = h.enq(x) +
        Places x in the PQ, and returns its index. +

        Map Class Prototypes

        +

        +Maps support associative array operations (insertion, deletion, and +membership of records based on an associated key). They require +the specification of two types, the key type and the contents type. +

        +These are currently implemented in several ways, differing in +representation strategy, algorithmic efficiency, and appropriateness for +various tasks. (Listed next to each are average (followed by worst-case, +if different) time complexities for [a] accessing (via op [], +contains), [d] deleting elements). +

        implement unordered Maps via chained hash tables. +([a O(1)/O(n)], [d O(1)/O(n)]). +

        +

        +

        +The different implementations differ in whether their constructors +require an argument specifying their initial capacity. Initial +capacities are required for hash table based Maps. If none is +given DEFAULT_INITIAL_CAPACITY (from `<T>defs.h') is +used.

        +All Map classes share the following operations (for some Map class, +Map instance d, Pix ind and key variable k, +and contents variable x). +

        +Pix-based operations are more fully described in the section +on Pixes. See section Pseudo-indexes +

        +

        +

        +

        Map d(x); Map d(x, int initial_capacity) +
        Declare d to be an empty Map. The required argument, x, specifies +the default contents, i.e., the contents of an otherwise +uninitialized location. The second version, specifying +initial capacity is allowed for Maps with an initial capacity +argument. +

        +

        d.empty() +
        returns true if d contains no items. +

        +

        d.length() +
        returns the number of items in d. +

        +

        d[k] +
        returns a reference to the contents of item with key k. If no +such item exists, it is installed with the default contents. +Thus d[k] = x installs x, and x = d[k] retrieves it. +

        +

        d.contains(k) +
        returns true if an item with key field k exists in d. +

        +

        d.del(k) +
        deletes the item with key k. +

        +

        d.clear() +
        deletes all items from the table. +

        +

        x = d.dflt() +
        returns the default contents. +

        +

        k = d.key(ind) +
        returns a reference to the key at Pix ind. +

        +

        x = d.contents(ind) +
        returns a reference to the contents at Pix ind. +

        +

        ind = d.first() +
        returns the Pix of the first element in d, or 0 if d is empty. +

        +

        d.next(ind) +
        advances ind to the next element, or 0 if there are no more. +

        +

        ind = d.seek(k) +
        returns the Pix of element with key k, or 0 if k is not in d. +

        +

        +

        +

        C++ version of the GNU getopt function

        +

        +The GetOpt class provides an efficient and structured mechanism for +processing command-line options from an application program. The sample +program fragment below illustrates a typical use of the GetOpt class +for some hypothetical application program: +

        +

        +#include <stdio.h>
+#include <GetOpt.h>
+//...
+int debug_flag, compile_flag, size_in_bytes;
+
+int
+main (int argc, char **argv)
+{
+  // Invokes ctor `GetOpt (int argc, char **argv, 
+  //                       char *optstring);'
+  GetOpt getopt (argc, argv, "dcs:");
+  int option_char;
+  
+  // Invokes member function `int operator ()(void);'
+  while ((option_char = getopt ()) != EOF)
+    switch (option_char)
+      {  
+         case 'd': debug_flag = 1; break;
+         case 'c': compile_flag = 1; break;
+         case 's': size_in_bytes = atoi (getopt.optarg); break;
+         case '?': fprintf (stderr, 
+                            "usage: %s [dcs<size>]\n", argv[0]);
+      }
+}
+
        +

        +Unlike the C library version, the libg++ GetOpt class uses its +constructor to initialize class data members containing the argument +count, argument vector, and the option string. This simplifies the +interface for each subsequent call to member function int operator +()(void). +

        +The C version, on the other hand, uses hidden static variables to retain +the option string and argument list values between calls to +getopt. This complicates the getopt interface since the +argument count, argument vector, and option string must be passed as +parameters for each invocation. For the C version, the loop in the +previous example becomes: +

        +

        +  while ((option_char = getopt (argc, argv, "dcs:")) != EOF)
+    // ...
+
        +

        +which requires extra overhead to pass the parameters for every call. +

        +Along with the GetOpt constructor and int operator ()(void), +the other relevant elements of class GetOpt are: +

        +

        +
        char *optarg +
        Used for communication from operator ()(void) to the caller. +When operator ()(void) finds an option that takes an argument, the +argument value is stored here. +
        int optind +
        Index in argv of the next element to be scanned. +This is used for communication to and from the caller +and for communication between successive calls to operator ()(void). + +When operator ()(void) returns EOF, this is the index of the +first of the non-option elements that the caller should itself scan. + +Otherwise, optind communicates from one call to the next how much +of argv has been scanned so far. +
        +

        +The libg++ version of GetOpt acts like standard UNIX getopt for +the calling routine, but it behaves differently for the user, since it +allows the user to intersperse the options with the other arguments. + +As GetOpt works, it permutes the elements of argv so that, when +it is done, all the options precede everything else. Thus all +application programs are extended to handle flexible argument order. +

        +Setting the environment variable _POSIX_OPTION_ORDER disables +permutation. Then the behavior is completely standard. +

        +

          +

        • +Additional container class prototypes. +

          +

        • +generic Matrix class prototypes. +

        +

        Wish List

        +

        +Some things that people have mentioned that they would like to +see in libg++, but for which there have not been any offers: +

        +

          +

          +

        • +A method to automatically convert or incorporate libg++ classes +so they can be used directly in Gorlen's OOPS environment. +

          +

        • +A class browser. +

          +

        How to contribute

        +

        +Programmers who have written C++ classes that they believe to +be of general interest are encourage to write to dl at rocky.oswego.edu. +Contributing code is not difficult. Here are some general guidelines: +

        +

          +

          +

        • +FSF must maintain the right to accept or reject potential contributions. +Generally, the only reasons for rejecting contributions are cases where +they duplicate existing or nearly-released code, contain unremovable +specific machine dependencies, or are somehow incompatible with the +rest of the library. +

          +

        • +Acceptance of contributions means that the code is accepted for adaptation +into libg++. FSF must reserve the right to make various editorial changes +in code. Very often, this merely entails formatting, maintenance of various +conventions, etc. Contributors are always given authorship credit and shown +the final version for approval. +

          +

        • +Contributors must assign their copyright to FSF via a form sent out +upon acceptance. Assigning copyright to FSF ensures that the code +may be freely distributed. +

          +

        • +Assistance in providing documentation, test files, and debugging +support is strongly encouraged. +

          +

        +

        +Extensions, comments, and suggested modifications of existing libg++ +features are also very welcome. diff --git a/reference/CPLUSPLUS/CONTRIB/GNU_STDLIB/libgpp_toc.html b/reference/CPLUSPLUS/CONTRIB/GNU_STDLIB/libgpp_toc.html new file mode 100644 index 0000000..f309159 --- /dev/null +++ b/reference/CPLUSPLUS/CONTRIB/GNU_STDLIB/libgpp_toc.html @@ -0,0 +1,124 @@ + + +to the GNU C++ Library - Table of Contents +

        class keyword

        +
        +

        +The concept of a class +allows you to +encapsulate + a set of related variables and only +allow access to them via predetermined functions. +

        + +The class keyword is used to declare the group of variables +and functions and the visability of the variables and functions. +Here is a basic example. + +

        +

        + + + + +
        +
        +
+    class String 
+    {
+    public:
+  
+        void Set(char *InputStr)   // Declare an Access function
+        { 
+            strcpy(Str, InputStr); 
+        }
+
+    private:
+        
+        char Str[80];      // Declare a hidden variable.
+  
+    };
+
        +
        +
        +

        + +

          +
        • private: means that all variables and functions that + follow are only visable from within the class. + +
        • public: all functions and variables that follow this + statement can be accessed from outside the class. +
        + +Now we have declared a class called String we need to +use it. +

        +

        + + + + +
        +
        +
+    main()
+    {
+        String Title;
+        
+        Title.Set("My First Masterpiece.");
+    }
+
        +
        +
        +

        + +This code creates a String +object +called Title and then uses the Set member function +to initialise the value of Str. +

        +In C++ the member function Set is also known as a +method +

        +This is the strength +of object oriented programming, the ONLY way to change +Str is via the Set method. + +

        + +The final code example brings the last two examples together +ands a new method (called Get) that shows the contents of +Str + +

        +

        + + + + +
        +
        +
+    #include <stdlib.h>
+    #include <iostream.h>               // Instead of stdio.h
+
+    class String 
+    {
+    public:
+  
+        void Set(char *InputStr)   // Declare an Access function
+        { 
+            strcpy(Str, InputStr); 
+        }
+        
+    char *Get(void)                // Declare an Access function
+        { 
+            return(Str); 
+        }
+        
+
+    private:
+        
+        char Str[80];      // Declare a hidden variable.
+  
+    };
+
+    main()
+    {
+        String Title;
+        
+        Title.Set("My First Masterpiece.");
+        
+        cout << Title.Get() << endl;
+    }
+

        NEW operator.

        +
        +

        +The new operator replaces the +malloc +function provided in C to reserve storage taken from the heap. +

        +The new operator requires one operand that describes the +type of data to be stored in the memory. Here are some examples. +

        +

        + + + + +
        +
        +
+    int *ptr1;                  // Declare a pointer to int.
+    ptr1 = new int;             // Reserve storage and point to it.
+    
+    float *ptr2 = new float;    // Do it all in one statement.
+    
+    delete ptr1;                // Free the storage.
+    delete ptr2;
+    
+    struct House                // Declare a complex structure.
+    {
+        int Floors;
+        int Windows;
+    };
+    
+    House *ptr3 = new House;    // Reserve storage and point to it.
+
+    delete ptr3;
+
        +
        +
        +

        + +Blocks or arrays of storage can also be reserved as show in the +next example. + +

        +

        + + + + +
        +
        +
+    char *ptr
+    ptr = new char[80];
+    
+    delete [] ptr;          // Free the storage.
+
        +
        +
        +

        + + + +Although new and +malloc +can be intermixed in the same code, it is probably best +to continue using +malloc +in existing code and new in new code. This is because +you can not use +delete with storage thats been +reserved with malloc and visa versa. If you keep to one +method or the other you are less likely to make a mistake. +

        +

        +
        + +

        +The struct keyword was introduced in 'C', its original functionality +is documented +here. +

        + +C++ has added two new features to structures. +

          +
        1. The syntax has been improved slightly so you no longer have to + mess around with typedef statements. + +

          +

          + + +
          +

          ANSI C approch to structures.

          +
          + 
          +
+    typedef struct Person {int age; char *name} Person_t;   
+
+    struct Person FirstMan;
+    Person_t      SecondMan;

          C++ structures.

          +
          + 
          +
+    struct Person {int age; char *name};

+
          +
          +

          +

          + +

        2. C++ also took the original idea of structures and added the ability to + associate functions with the data within the structure. This feature + was wrapped up with the introduction of the + class keyword. +
        +
