gets, fgets - get a string from a stream
SYNOPSIS
#include <stdio.h>
char *gets(char *s);
char *fgets(char *s,
int n,
FILE *stream);
MT-LEVEL
MT-Safe
DESCRIPTION
gets()
reads characters
from the standard input stream
(see
intro.3
stdin,
into the array pointed to by
s,
until a newline character is read
or an end-of-file condition is encountered.
The newline character is discarded
and the string is terminated with a null character.
fgets()
reads characters from the
stream
into the array pointed to by
s,
until
n-1
characters are read, or
a newline character is read and transferred to
s,
or an end-of-file condition is encountered.
The string is then terminated with a
null character.
When using
gets(),
if the length of an input line exceeds the size of s,
indeterminate behavior may result.
For this reason, it is strongly recommended that
gets()
be avoided in favor of
fgets().
RETURN VALUES
If end-of-file is encountered and no characters have been read,
no characters are transferred to
s
and a
null pointer is returned.
If a read error occurs, such as trying to use these functions
on a file that has not been opened for reading, a
null pointer is returned and the error indicator for the stream is set.
If end-of-file is encountered, the
EOF
indicator for the stream is set. Otherwise
s
is returned.
