NAME
gets, fgets - get a string from a stream
SYNOPSIS
#include <stdio.h>
char *gets(s)
char *s;
char *fgets(s, n, stream)
char *s;
FILE *stream;
DESCRIPTION
Gets 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. Gets returns its argument.
Fgets 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. Fgets returns its first
argument.
SEE ALSO
puts(3), getc(3), scanf(3), fread(3), ferror(3)
DIAGNOSTICS
Gets and fgets return the constant pointer NULL upon end of file or er‐
ror.
BUGS
Gets deletes a newline, fgets keeps it, all in the name of backward
compatibility.
