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:
               _XOPEN_SOURCE && ! (_POSIX_C_SOURCE >= 200112L)
                   || /* Glibc since 2.19: */ _DEFAULT_SOURCE
                   || /* Glibc versions <= 2.19: */ _BSD_SOURCE || _SVID_SOURCE
           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.

BUGS

       The value returned on error is also a legitimate data  value.   ferror(3)  can  be  used  to  distinguish
       between the two cases.
