<h3 class="section">6.8 <code>wcscmp</code>&mdash;compare two wide-character strings</h3>
<p><strong>Synopsis</strong>
</p><div class="example">
<pre class="example">#include &lt;wchar.h&gt;
int wcscmp(const wchar_t *<var>s1</var>, *<var>s2</var>);

</pre></div>
<p><strong>Description</strong><br>
The <code>wcscmp</code> function compares the wide-character string pointed to
by <var>s1</var> to the wide-character string pointed to by <var>s2</var>.
</p>
<p>The sign of a non-zero return value is determined by the sign of the
difference between the values of the first pair of wide-character codes
that differ in the objects being compared.
</p>
<br>
<p><strong>Returns</strong><br>
Upon completion, <code>wcscmp</code> returns an integer greater than, equal to
or less than 0, if the wide-character string pointed to by <var>s1</var> is
greater than, equal to or less than the wide-character string pointed
to by <var>s2</var> respectively. 
</p>
<br>
<p><strong>Portability</strong><br>
<code>wcscmp</code> is ISO/IEC 9899/AMD1:1995 (ISO C).
</p>
<p>No supporting OS subroutines are required.
