/***
*_wctype.c - function versions of wctype macros
*
* Copyright (c) 1991-1997, Microsoft Corporation. All rights reserved.
*
*Purpose:
* This file provides function versions of the wide character
* classification and conversion macros in ctype.h.
*
*******************************************************************************/
/***
*wctype - Function versions of wctype macros
*
*Purpose:
* Function versions of the wide char macros in ctype.h,
* including isleadbyte and iswascii. In order to define
* these, we use a trick -- we undefine the macro so we can use the
* name in the function declaration, then re-include the file so
* we can use the macro in the definition part.
*
* Functions defined:
* iswalpha iswupper iswlower
* iswdigit iswxdigit iswspace
* iswpunct iswalnum iswprint
* iswgraph iswctrl iswascii
* isleadbyte
*
*Entry:
* wchar_t c = character to be tested
*Exit:
* returns non-zero = character is of the requested type
* 0 = character is NOT of the requested type
*
*Exceptions:
* None.
*
