/***
*wcscat.c - contains wcscat() and wcscpy()
*
* Copyright (c) 1985-2001, Microsoft Corporation. All rights reserved.
*
*Purpose:
* wcscat() appends one wchar_t string onto another.
* wcscpy() copies one wchar_t string into another.
*
* wcscat() concatenates (appends) a copy of the source string to the
* end of the destination string, returning the destination string.
* Strings are wide-character strings.
*
* wcscpy() copies the source string to the spot pointed to be
* the destination string, returning the destination string.
* Strings are wide-character strings.
*
*Revision History:
* 09-09-91 ETC Created from strcat.c.
* 04-07-92 KRS Updated and ripped out _INTL switches.
* 04-06-93 SKS Replace _CRTAPI* with __cdecl
* 02-07-94 CFW POSIXify.
