fgets function

+fgets is used to read a line of data from an external source.

+ +

+Library:   stdio.h
+
+Prototype: char *fgets(char *s, int n, FILE *stream);
+
+Syntax:    char  Data[80];
+	   char *ReturnCode;
+	   FILE *FilePointer;
+
+	   ReturnCode=fgets(Data, 80, FilePointer);
+
+	   ReturnCode == NULL when an error occours. The EOF is 
+	   considered to be an ERROR!
+

+ +

Notes

fgets should be used in preference to gets +as it checks that the incoming data does not exceed the buffer size. +
+ +
If fgets is reading STDIN, the +NEWLINE character is placed into +the buffer. gets removes the NEWLINE. +

+ +

+ example program number one.

+ + + example program number two.

+ + + program comparing the action of gets and fgets when reading STDIN.
