GETW(3)                   (2016-03-15)                    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)):

          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.
