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 through a newline character, whichever comes first, from the stream into the string s.  The last  charac-
       ter read into s is followed by a null character.  Fgets returns its first argument.

SEE ALSO
       puts(3S), getc(3S), scanf(3S), fread(3S), ferror(3S)

DIAGNOSTICS
       Gets and fgets return the constant pointer NULL upon end of file or error.

BUGS
       Gets deletes a newline, fgets keeps it, all in the name of backward compatibility.
