/* FUNCTION <<wcscat>>---concatenate two wide-character strings INDEX wcscat ANSI_SYNOPSIS #include <wchar.h> wchar_t *wcscat(wchar_t *<[s1]>, const wchar_t *<[s2]>); TRAD_SYNOPSIS wchar_t *wcscat(<[s1]>, <[s2]> wchar_t *<[s1]>; const wchar_t *<[s2]>; DESCRIPTION The <<wcscat>> function appends a copy of the wide-character string pointed to by <[s2]> (including the terminating null wide-character code) to the end of the wide-character string pointed to by <[s1]>. The initial wide-character code of <[s2]> overwrites the null wide-character code at the end of <[s1]>. If copying takes place between objects that overlap, the behaviour is undefined. RETURNS The <<wcscat>> function returns <[s1]>; no return value is reserved to indicate an error. PORTABILITY <<wcscat>> is ISO/IEC 9899/AMD1:1995 (ISO C). No supporting OS subroutines are required. */ /* $NetBSD: wcscat.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.
