/*FUNCTION	<<wmemcmp>>---compare wide-characters in memory ANSI_SYNOPSIS	#include <wchar.h>	int wmemcmp(const wchar_t *<[s1]>, const wchar_t *<[s2]>, size_t <[n]>);TRAD_SYNOPSIS	int wmemcmp(<[s1]>, <[s2]>, <[n]>	const wchar_t *<[s1]>;	const wchar_t *<[s2]>;	size_t <[n]>;DESCRIPTION	The <<wmemcmp>> function compares the first <[n]> wide-characters of the	object pointed to by <[s1]> to the first <[n]> wide-characters of the	object pointed to by <[s2]>. This function is not affected by locale	and all wchar_t values are treated identically. The null wide-character	and wchar_t values not corresponding to valid characters are not treated	specially.	If <[n]> is zero, <[s1]> and <[s2]> must be a valid pointers and the	function behaves as if the two objects compare equal. RETURNS	The <<wmemcmp>> function returns an integer greater than, equal to,	or less than zero, accordingly as the object pointed to by <[s1]> is	greater than, equal to, or less than the object pointed to by <[s2]>.PORTABILITY<<wmemcmp>> is ISO/IEC 9899/AMD1:1995 (ISO C).No supporting OS subroutines are required.*//*	$NetBSD: wmemcmp.c,v 1.1 2000/12/23 23:14:37 itojun Exp $	*//*- * Copyright (c)1999 Citrus Project, * All rights reserved. * * Redistribution and use in source and binary forms, with or without * modification, are permitted provided that the following conditions * are met: * 1.
