/*FUNCTION	<<wmemchr>>---find a wide-character in memory ANSI_SYNOPSIS	#include <wchar.h>	wchar_t	*wmemchr(const wchar_t *<[s]>, wchar_t <[c]>, size_t <[n]>);TRAD_SYNOPSIS	wchar_t	*wmemchr(<[s]>, <[c]>, <[n]>	const wchar_t *<[s]>;	wchar_t <[c]>;	size_t <[n]>;DESCRIPTION	The <<wmemchr>> function locates the first occurrence of <[c]> in the	initial <[n]> wide-characters of the object pointed to be <[s]>. 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, <[s]> must be a valid pointer and the function	behaves as if no valid occurrence of <[c]> is found. RETURNS	The <<wmemchr>> function returns a pointer to the located	wide-character, or a null pointer if the wide-character does not occur	in the object. PORTABILITY<<wmemchr>> is ISO/IEC 9899/AMD1:1995 (ISO C).No supporting OS subroutines are required.*//*	$NetBSD: wmemchr.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.
