NAME
getw, putw - input and output of words (ints)
SYNOPSIS
#include <stdio.h>
int getw(FILE *stream);
int putw(int w, FILE *stream);
Feature Test Macro Requirements for glibc (see
feature_test_macros(7)):
getw(),
putw():
-
- Since glibc 2.3.3:
-
_SVID_SOURCE || _BSD_SOURCE ||
(_XOPEN_SOURCE &&
!(_POSIX_C_SOURCE >= 200112L || _XOPEN_SOURCE >= 600))
- Before glibc 2.3.3:
-
_SVID_SOURCE || _BSD_SOURCE || _XOPEN_SOURCE
DESCRIPTION
getw()
reads a word (that is, an int) from stream.
It's provided for compatibility with SVr4.
We recommend you use
fread(3)
instead.
putw()
writes the word w (that is,
an int) to stream.
It is provided for compatibility with SVr4, but we recommend you use
fwrite(3)
instead.
RETURN VALUE
Normally,
getw()
returns the word read, and
putw()
returns 0.
On error, they return EOF.
CONFORMING TO
SVr4, SUSv2.
Not present in POSIX.1-2001.
BUGS
The value returned on error is also a legitimate data value.
ferror(3)
can be used to distinguish between the two cases.
