<p><strong>Synopsis</strong>
|
||
|
|
</p><div class="example">
|
||
|
|
<pre class="example">#include <wchar.h>
|
||
|
|
size_t wcslcat(wchar_t *<var>dst</var>, const wchar_t *<var>src</var>, size_t <var>siz</var>);

</pre></div>
|
||
|
|
<p><strong>Description</strong><br>
|
||
|
|
The <code>wcslcat</code> function appends wide characters from <var>src</var> to
|
||
|
|
end of the <var>dst</var> wide-character string so that the resultant
|
||
|
|
wide-character string is not more than <var>siz</var> wide characters
|
||
|
|
including the terminating null wide-character code. A terminating
|
||
|
|
null wide character is always added unless <var>siz</var> is 0. Thus,
|
||
|
|
the maximum number of wide characters that can be appended from
|
||
|
|
<var>src</var> is <var>siz</var> - 1. If copying takes place between objects
|
||
|
|
that overlap, the behaviour is undefined.
|
||
|
|
</p>
|
||
|
|
<br>
|
||
|
|
<p><strong>Returns</strong><br>
|
||
|
|
Wide-character string length of initial <var>dst</var> plus the
|
||
|
|
wide-character string length of <var>src</var> (does not include
|
||
|
|
terminating null wide-characters). If the return value is
|
||
|
|
greater than or equal to <var>siz</var>, then truncation occurred and
|
||
|
|
not all wide characters from <var>src</var> were appended.
|
||
|
|
</p>
|

|
|
<p><strong>Portability</strong><br>
|
||
|
|
No supporting OS subroutines are required.
