GETW(3) Linux Programmer's Manual GETW(3)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)):
gutw(), 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 _GNU_SOURCE
DESCRIPTIONgetw() 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.
