|
|
<p><strong>Synopsis</strong>
|
|
</p><div class="example">
|
|
<pre class="example">#include <wchar.h>
|
|
wchar_t *wcsstr(const wchar_t *__restrict <var>big</var>,

|
const wchar_t *__restrict <var>little</var>);

|
<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).
