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.
