/* 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.
