The wcscasecmp () function is the wide-character equivalent of the strcasecmp (3) function. It compares the wide-character string pointed to by s1 and the wide-character string pointed to by s2 , ignoring case differences ( towupper (3), towlower (3)).

RETURN VALUE

The wcscasecmp () function returns zero if the wide-character strings at s1 and s2 are equal except for case distinctions. It returns a positive integer if s1 is greater than s2 , ignoring case. It returns a negative integer if s1 is smaller than s2 , ignoring case.
