<pre class="example">#include <wchar.h>

wchar_t *wcsrchr(const wchar_t *<var>s</var>, wchar_t <var>c</var>);

<p><strong>Description</strong><br>
|
||
|
|
The <code>wcsrchr</code> function locates the last occurrence of <var>c</var> in the
|
||
|
|
wide-character string pointed to by <var>s</var>. The value of <var>c</var> must be a
|
||
|
|
character representable as a type wchar_t and must be a wide-character
|
||
|
|
code corresponding to a valid character in the current locale.
|
||
|
|
The terminating null wide-character code is considered to be part of
|
||
|
|
the wide-character string.
|
||
|
|
</p>
|
||
|
|
<br>
|
||
|
|
<p><strong>Returns</strong><br>
|
||
|
|
Upon successful completion, <code>wcsrchr</code> returns a pointer to the
|
||
|
|
wide-character code or a null pointer if <var>c</var> does not occur in the
|
||
|
|
wide-character string.
|
||
|
|
</p>
|
||
|
|
<br>
|
||
|
|
<p><strong>Portability</strong><br>
|
||
|
|
<code>wcsrchr</code> is ISO/IEC 9899/AMD1:1995 (ISO C).
|
||
|
|
</p>
|
||
|
|
<p>No supporting OS subroutines are required.
