<h3 class="section">6.26 <code>wcsstr</code>&mdash;find a wide-character substring</h3>
<p><strong>Synopsis</strong>
</p><div class="example">
<pre class="example">#include &lt;wchar.h&gt;
wchar_t *wcsstr(const wchar_t *__restrict <var>big</var>,
    const wchar_t *__restrict <var>little</var>);

</pre></div>
<p><strong>Description</strong><br>
The <code>wcsstr</code> function locates the first occurrence in the
wide-character string pointed to by <var>big</var> of the sequence of
wide characters (excluding the terminating null wide character) in the
wide-character string pointed to by <var>little</var>.
</p>
<br>
<p><strong>Returns</strong><br>
On successful completion, <code>wcsstr</code> returns a pointer to the located
wide-character string, or a null pointer if the wide-character string
is not found.
</p>
<p>If <var>little</var> points to a wide-character string with zero length,
the function returns <var>big</var>.
</p>
<br>
<p><strong>Portability</strong><br>
<code>wcsstr</code> is ISO/IEC 9899/AMD1:1995 (ISO C).
