<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.

|
||
|

No supporting OS subroutines are required.
