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

wchar_t *wmemcpy(wchar_t *__restrict <var>d</var>,

<p><strong>Description</strong><br>
|
||
|
|
The <code>wmemcpy</code> function copies <var>n</var> wide characters from the object
|
||
|
|
pointed to by <var>s</var> to the object pointed to be <var>d</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>d</var> and <var>s</var> must be a valid pointers, and the
|
||
|
|
function copies zero wide characters.
|
||
|
|
</p>
|
||
|
|
<br>
|
||
|
|
<p><strong>Returns</strong><br>
|
||
|
|
The <code>wmemcpy</code> function returns the value of <var>d</var>.
|
||
|
|
</p>
|
||
|
|
<br>
|
||
|
|
<p><strong>Portability</strong><br>
|
||
|
|
<code>wmemcpy</code> is ISO/IEC 9899/AMD1:1995 (ISO C).
|
||
|
|
</p>
|
||
|
|
<p>No supporting OS subroutines are required.
