wcscoll

   Compares two wide-character strings and returns an integer
   that indicates if the strings differ, and how they differ.
   The function uses the collating information in the LC_COLLATE
   category of the current locale to determine how the comparison is
   performed.

   Format

     #include  <wchar.h>

     int wcscoll  (const wchar_t *ws1, const wchar_t *ws2);
