|

|
|
<p><strong>Synopsis</strong>
|
||
|
|
</p><div class="example">
|
||
|
|
<pre class="example">#include <wchar.h>
|
||
|
|
wchar_t *wmemchr(const wchar_t *<var>s</var>, wchar_t <var>c</var>, size_t <var>n</var>);
|
||
|
|
|
||
|
|
</pre></div>
|
||
|
|
<p><strong>Description</strong><br>
|
||
|
|
The <code>wmemchr</code> function locates the first occurrence of <var>c</var> in the
|
||
|
|
initial <var>n</var> wide characters of the object pointed to be <var>s</var>. This
|
||
|
|
function is not affected by locale and all wchar_t values are treated
|
||
|
|
identically. The null wide character and wchar_t values not
|
||
|
|
corresponding to valid characters are not treated specially.
|
||
|
|
</p>
|
||
|
|
<p>If <var>n</var> is zero, <var>s</var> must be a valid pointer and the function
|
||
|
|
behaves as if no valid occurrence of <var>c</var> is found.
|
||
|
|
</p>
|
||
|
|
<br>
|
||
|
|
<p><strong>Returns</strong><br>
|
||
|
|
The <code>wmemchr</code> function returns a pointer to the located
|
||
|
|
wide character, or a null pointer if the wide character does not occur
|
||
|
|
in the object.
|
||
|
|
</p>
|
||
|
|
<br>
|
||
|
|
<p><strong>Portability</strong><br>
|
||
|
|
<code>wmemchr</code> is ISO/IEC 9899/AMD1:1995 (ISO C).
|
||
|
|
</p>
|
||
|
|
<p>No supporting OS subroutines are required.
