*tchar.h - definitions for generic international text functions
*
* Copyright (c) 1991-1993, Microsoft Corporation. All rights reserved.
*
*Purpose:
* Definitions for generic international functions, mostly defines
* which map string/formatted-io/ctype functions to char, wchar_t, or
* MBCS versions. To be used for compatibility between single-byte,
* multi-byte and Unicode text models.
