<p><strong>Synopsis</strong>
|
|
</p><div class="example">
|
|
<pre class="example">#include <stdio.h>
|
|
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’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&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>.
