<h3 class="section">4.40 <code>getw</code>&mdash;read a word (int)</h3>
<a name="index-getw"></a>
<p><strong>Synopsis</strong>
</p><div class="example">
<pre class="example">#include &lt;stdio.h&gt;
int getw(FILE *<var>fp</var>);

</pre></div>
<p><strong>Description</strong><br>
<code>getw</code> is a function, defined in <code>stdio.h</code>.  You can use <code>getw</code>
to get the next word from the file or stream identified by <var>fp</var>.  As
a side effect, <code>getw</code> advances the file&rsquo;s current position
indicator.
</p>
<br>
<p><strong>Returns</strong><br>
The next word (read as an <code>int</code>), unless there is no more
data or the host system reports a read error; in either of these
situations, <code>getw</code> returns <code>EOF</code>.  Since <code>EOF</code> is a valid
<code>int</code>, you must use <code>ferror</code> or <code>feof</code> to distinguish these
situations.
</p>
<br>
<p><strong>Portability</strong><br>
<code>getw</code> is a remnant of K&amp;R C; it is not part of any ISO C Standard.
<code>fread</code> should be used instead.  In fact, this implementation of
<code>getw</code> is based upon <code>fread</code>.
</p>
<p>Supporting OS subroutines required: <code>fread</code>.
