wcscoll —
#include <wchar.h>
int
  
  wcscoll(const
    wchar_t *s1, const
    wchar_t *s2);
wcscoll() function compares the nul-terminated
  strings s1 and s2 according to the
  current locale collation order. In the
  “C” locale,
  wcscoll() is equivalent to
  wcscmp().
wcscoll() function returns an integer greater than,
  equal to, or less than 0, if s1 is greater than, equal
  to, or less than s2.
No return value is reserved to indicate errors; callers should set
    errno to 0 before calling
    wcscoll(). If it is non-zero upon return from
    wcscoll(), an error has occurred.
wcscoll() function will fail if:
wcscoll() function conforms to
  ISO/IEC 9899:1999 (“ISO C99”).
wcscoll() function
  disregards LC_COLLATE locales, and falls back to using
  the wcscmp() function.
