<h3 class="section">6.15 <code>wcslcpy</code>—copy a wide-character string to specified length</h3>
<p><strong>Synopsis</strong>
</p><div class="example">
<pre class="example">#include <wchar.h>
size_t wcslcpy(wchar_t *<var>dst</var>, const wchar_t *<var>src</var>, size_t <var>siz</var>);
</pre></div>
<p><strong>Description</strong><br>
<code>wcslcpy</code> copies wide characters from <var>src</var> to <var>dst</var>
such that up to <var>siz</var> - 1 characters are copied. A
terminating null is appended to the result, unless <var>siz</var>
is zero.
</p>
<br>
<p><strong>Returns</strong><br>
<code>wcslcpy</code> returns the number of wide characters in <var>src</var>,
not including the terminating null wide character. If the
return value is greater than or equal to <var>siz</var>, then
not all wide characters were copied from <var>src</var> and truncation
occurred.
</p>
<br>
<p><strong>Portability</strong><br>
No supporting OS subroutines are required.
