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

SYNOPSIS
       #include <wchar.h>

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

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       wcscasecmp():
	   Since glibc 2.10:
	       _POSIX_C_SOURCE >= 200809L
	   Before glibc 2.10:
	       _GNU_SOURCE

DESCRIPTION
       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.

VERSIONS
       The wcscasecmp() function is provided in glibc since version 2.1.
