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

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.
