| <h3 class="section">6.28 <code>wcsxfrm</code>—locale-specific wide-character string transformation</h3> |
| |
| <p><a name="index-wcsxfrm-421"></a><strong>Synopsis</strong> |
| <pre class="example"> #include <wchar.h> |
| int wcsxfrm(wchar_t *<var>stra</var>, const wchar_t * <var>strb</var>, size_t <var>n</var>); |
| |
| </pre> |
| <p><strong>Description</strong><br> |
| <code>wcsxfrm</code> transforms the wide-character string pointed to by |
| <var>strb</var> to the wide-character string pointed to by <var>stra</var>, |
| Comparing two transformed wide strings with <code>wcscmp</code> should return |
| the same result as comparing the original strings with <code>wcscoll</code>. |
| No more than <var>n</var> wide characters are transformed, including the |
| trailing null character. |
| |
| <p>If <var>n</var> is 0, <var>stra</var> may be a NULL pointer. |
| |
| <p>The current implementation of <code>wcsxfrm</code> simply uses <code>wcslcpy</code> |
| and does not support any language-specific transformations. |
| |
| <p><br> |
| <strong>Returns</strong><br> |
| <code>wcsxfrm</code> returns the length of the transformed wide character |
| string. if the return value is greater or equal to <var>n</var>, the |
| content of <var>stra</var> is undefined. |
| |
| <p><br> |
| <strong>Portability</strong><br> |
| <code>wcsxfrm</code> is ISO/IEC 9899/AMD1:1995 (ISO C). |
