NAME
       wcscasecmp - compare two wide-character strings, ignoring case

SYNOPSIS
       #include <wchar.h>

       int wcscasecmp(const wchar_t *s1, const wchar_t *s2);

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

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  posi-
       tive integer if s1 is greater than s2, ignoring case. It returns a negative integer if s1 is smaller than s2, ignoring case.

CONFORMING TO
       This function is a GNU extension.

SEE ALSO
       strcasecmp(3), wcscmp(3)

NOTES
       The behaviour of wcscasecmp depends on the LC_CTYPE category of the current locale.
