NAME
gets, fgets − get a string from a stream
SYNTAX
#include <stdio.h>
char *gets(s)
char *s;
char *fgets(s, n, stream)
char *s;
FILE *stream;
DESCRIPTION
The gets routine reads a string into s from the standard input stream stdin. The string is terminated by a newline character, which is replaced in s by a null character. The gets routine returns its argument.
The fgets routine reads n−1 characters, or up to a newline character, whichever comes first, from the stream into the string s. The last character read into s is followed by a null character. The fgets routine returns its first argument.
DIAGNOSTICS
The gets and fgets routines return the constant pointer NULL upon end of file or error.
RESTRICTIONS
The gets routine deletes a newline, while fgets keeps it.
