/*FUNCTION	<<wcscspn>>---get length of a complementary wide substring ANSI_SYNOPSIS	#include <wchar.h>	size_t wcscspn(const wchar_t *<[s]>, wchar_t *<[set]>);TRAD_SYNOPSIS	size_t wcscspn(<[s]>, <[set]>	const wchar_t *<[s]>;	const wchar_t *<[set]>;DESCRIPTION	The <<wcscspn>> function computes the length of the maximum initial	segment of the wide-character string pointed to by <[s]> which consists	entirely of wide-character codes not from the wide-character string	pointed to by <[set]>. RETURNS	The <<wcscspn>> function returns the length of the initial substring of	<[s1]>; no return value is reserved to indicate an error.PORTABILITY<<wcscspn>> is ISO/IEC 9899/AMD1:1995 (ISO C).No supporting OS subroutines are required.*//*	$NetBSD: wcscspn.c,v 1.1 2000/12/23 23:14:36 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.
