char *fgets( char *s, int n, FILE *fp )


char *s;       /* character buffer */

int   n;       /* maximum length */

FILE *fp;      /* open input stream */




#include "stdio.h"


The fgets function reads a string from stream fp , and stores it into the character buffer pointed to by s . fgets reads until either a newline or n - 1 characters are encountered; the string is guaranteed to be null-terminated.




s is the address of a character buffer, at least n bytes in length. fp is a stream pointer, open for input.



Return Value

fgets returns NULL (0L) if an error occurs or end-of-file is encountered before any characters have been read; otherwise, fgets returns s.
