* Name: wcsxfrm
|
|
*
|
|
* Description:
|
|
* The wcsxfrm() transforms the wide-character string pointed to by b to
|
|
* the wide-character string pointed to by a, comparing two transformed
|
|
* wide strings with wcscmp() should return the same result as comparing
|
|
* the original strings with wcscoll().
|
|
* No more than n wide characters are transformed, including the trailing
|
|
* null character. The current implementation of wcsxfrm() simply uses
|
|
* wcslcpy() and does not support any language-specific transformations.
