GETW

Linux Programmer's Manual (3)
2010-09-26
 

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.  

SEE ALSO

ferror(3), fread(3), fwrite(3), getc(3), putc(3)
