GETS(3S)GETS(3S)NAME
gets, fgets - get a string from a stream
SYNOPSIS
#include <stdio.h>
char *gets(char *s);
char *fgets(char *s, int n, FILE *stream);
DESCRIPTION
Gets reads a string into s from the standard input stream stdin, until
end-of-file is encountered or a new-line character is read. The string
is terminated by a newline character, which is replaced in s by a null
character.
Fgets reads n-1 characters, or up through a newline character,
whichever comes first, from the stream into the string s. No
additional characters are read after a new-line character (which is
retained) or after end-of-file. The last character read into s is
followed by a null character.
RETURN VALUE
Fgets and gets returns s if successful. If unsuccessful, a null
pointer is returned and an error code is stored in errno.
ERRORS
The underlying function of fgets and gets is read(2). The error
conditions specified for read(2) apply to fgets and gets.
SEE ALSOread(2), 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.
