<p><strong>Synopsis</strong>

<pre class="example">#include <wchar.h>
|

int wcscoll(const wchar_t *<var>stra</var>, const wchar_t * <var>strb</var>);

|
<p><strong>Description</strong><br>
|
||
|
|
<code>wcscoll</code> compares the wide-character string pointed to by
|
||
|
|
<var>stra</var> to the wide-character string pointed to by <var>strb</var>,
|
||
|
|
using an interpretation appropriate to the current <code>LC_COLLATE</code>
|
||
|
|
state.
|
||
|
|
</p>
|
||
|
|
<p>(NOT Cygwin:) The current implementation of <code>wcscoll</code> simply
|
||
|
|
uses <code>wcscmp</code> and does not support any language-specific sorting.
|
||
|
|
</p>
|
||
|
|
<br>
|
||
|
|
<p><strong>Returns</strong><br>
|
||
|
|
If the first string is greater than the second string,
|
||
|
|
<code>wcscoll</code> returns a number greater than zero. If the two
|
||
|
|
strings are equivalent, <code>wcscoll</code> returns zero. If the first
|
||
|
|
string is less than the second string, <code>wcscoll</code> returns a
|
||
|
|
number less than zero.
|
||
|
|
</p>
|
||
|
|
<br>
|
||
|
|
<p><strong>Portability</strong><br>
|
||
|
|
<code>wcscoll</code> is ISO/IEC 9899/AMD1:1995 (ISO C).
