/*FUNCTION	<<wcscmp>>---compare two wide-character stringsANSI_SYNOPSIS	#include <wchar.h>	int wcscmp(const wchar_t *<[s1]>, *<[s2]>);TRAD_SYNOPSIS	int wcscmp(<[s1]>, <[s2]>	const wchar_t *<[s1]>, <[s2]>;DESCRIPTION	The <<wcscmp>> function compares the wide-character string pointed to	by <[s1]> to the wide-character string pointed to by <[s2]>.	The sign of a non-zero return value is determined by the sign of the	difference between the values of the first pair of wide-character codes	that differ in the objects being compared.RETURNS	Upon completion, <<wcscmp>> returns an integer greater than, equal to	or less than 0, if the wide-character string pointed to by <[s1]> is	greater than, equal to or less than the wide-character string pointed	to by <[s2]> respectively. PORTABILITY<<wcscmp>> is ISO/IEC 9899/AMD1:1995 (ISO C).No supporting OS subroutines are required.*//*	$NetBSD$	*//*- * Copyright (c) 1990, 1993 *	The Regents of the University of California.
