<h3 class="section">6.4 <code>wmemmove</code>&mdash;copy wide characters in memory with overlapping areas</h3>
<p><strong>Synopsis</strong>
</p><div class="example">
<pre class="example">#include &lt;wchar.h&gt;
wchar_t *wmemmove(wchar_t *<var>d</var>, const wchar_t *<var>s</var>, size_t <var>n</var>);

</pre></div>
<p><strong>Description</strong><br>
The <code>wmemmove</code> function copies <var>n</var> wide characters from the object
pointed to by <var>s</var> to the object pointed to by <var>d</var>. Copying takes
place as if the <var>n</var> wide characters from the object pointed to by
<var>s</var> are first copied into a temporary array of <var>n</var> wide characters
that does not overlap the objects pointed to by <var>d</var> or <var>s</var>, and then
the <var>n</var> wide characters from the temporary array are copied into the
object pointed to by <var>d</var>.
</p>
<p>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>wmemmove</code> function returns the value of <var>d</var>.
</p>
<br>
<p><strong>Portability</strong><br>
<code>wmemmove</code> is ISO/IEC 9899/AMD1:1995 (ISO C).
</p>
<p>No supporting OS subroutines are required.
</p>
