This is a summary of ANSI and POSIX functions grouped by library. If you want an alphabetical list, please use the master index. Please refer to a manual for a complete list of functions available to you.
| assert.h | ctype.h | errno.h | float.h | limits.h |
| locale.h | math.h | setjmp.h | signal.h | stdarg.h |
| stddef.h | stdio.h | stdlib.h | string.h | time.h |
POSIX library
The POSIX library contains
the following headers.
| cpio.h | dirent.h | fcntl.h | grp.h | pwd.h |
| sys/stat.h | sys/times.h | sys/types.h | sys/utsname.h | sys/wait.h |
| tar.h | termios.h | unistd.h | utime.h |
See also vprintf vfprintf and vsprintf which all print the contents of a va_list
stddef.h
No functions are declared in stddef.h.
stdio.h
This header defines all the ANSI I/O functions that allow you to read
and write to files and devices.
Low level (non ANSI) functions are also available.
stdlib.h
string.h
time.h
POSIX functions start here....
cpio.h
dirent.h
fcntl.h
grp.h
pwd.h
sys/stat.h
sys/times.h
sys/types.h
sys/utsname.h
sys/wait.h
tar.h
termios.h
unistd.h
It seems that this library contains headers for many functions that originally came with the ANSII
standard library but did not have headers.
My documentation for this POSIX library is incomplete.
utime.h
conio.h
Dos Specific functions in conio.h Not very portable as conio.h
is NOT in the ANSI standard library and does not
appear on the Sun or Linux machines.
