<blockquote>
<div class="box"><sup>[<a href="javascript:open_code('CX')">CX</a>]</sup> <img src="../images/opt-start.gif" alt="[Option Start]"
border="0"> The functionality described on this reference page is aligned with the ISO&nbsp;C standard. Any conflict between the
requirements described here and the ISO&nbsp;C standard is unintentional. This volume of IEEE&nbsp;Std&nbsp;1003.1-2001 defers to
the ISO&nbsp;C standard. <img src="../images/opt-end.gif" alt="[Option End]" border="0"></div>
<p>The <i>wmemmove</i>() function shall copy <i>n</i> wide characters from the object pointed to by <i>ws2</i> to the object
pointed to by <i>ws1</i>. Copying shall take place as if the <i>n</i> wide characters from the object pointed to by <i>ws2</i> are
first copied into a temporary array of <i>n</i> wide characters that does not overlap the objects pointed to by <i>ws1</i> or
<i>ws2</i>, and then the <i>n</i> wide characters from the temporary array are copied into the object pointed to by <i>ws1</i>.</p>
<p>This function shall not be affected by locale and all <b>wchar_t</b> values shall be treated identically. The null wide
character and <b>wchar_t</b> values not corresponding to valid characters shall not be treated specially.</p>
<p>If <i>n</i> is zero, the application shall ensure that <i>ws1</i> and <i>ws2</i> are valid pointers, and the function shall copy
zero wide characters.</p>
</blockquote>
<h4><a name="tag_03_862_04"></a>RETURN VALUE</h4>
<blockquote>
<p>The <i>wmemmove</i>() function shall return the value of <i>ws1</i>.</p>
