/*** *ctype.h - character conversion macros and ctype macros * * Copyright (c) 1985-1993, Microsoft Corporation. All rights reserved. * *Purpose: * Defines macros for character classification/conversion. * [ANSI/System V] * *Revision History: * 07-31-87 PHG changed (unsigned char)(c) to (0xFF & (c)) to * suppress -W2 warning * 08-07-87 SKS Removed (0xFF & (c)) -- is????() functions take an (int) * 12-18-87 JCR Added _FAR_ to declarations * 01-19-87 JCR DLL routines * 02-10-88 JCR Cleaned up white space * 08-19-88 GJF Modify to also work for the 386 (small model only) * 12-08-88 JCR DLL now access _ctype directly (removed DLL routines) * 03-26-89 GJF Brought into sync with CRT\H\CTYPE.H * 05-03-89 JCR Added _INTERNAL_IFSTRIP for relinc usage * 07-28-89 GJF Cleanup, now specific to OS/2 2.0 (i.e., 386 flat model) * 10-30-89 GJF Fixed copyright, removed dummy args from prototypes * 11-02-89 JCR Changed "DLL" to "_DLL" * 02-28-90 GJF Added #ifndef _INC_CTYPE and #include * stuff. Also, removed #ifndef _CTYPE_DEFINED stuff and * some other (now) useless preprocessor directives. * 03-22-90 GJF Replaced _cdecl with _CALLTYPE1 in prototypes and * with _VARTYPE1 in variable declarations. * 01-16-91 GJF ANSI naming. * 03-21-91 KRS Added isleadbyte macro. * 08-20-91 JCR C++ and ANSI naming * 09-28-91 JCR ANSI names: DOSX32=prototypes, WIN32=#defines for now * 10-11-91 ETC All under _INTL: isleadbyte/isw* macros, prototypes; * new is* macros; add wchar_t typedef; some intl defines. * 12-17-91 ETC ctype width now independent of _INTL, leave original * short ctype table under _NEWCTYPETABLE. * 01-22-92 GJF Changed definition of _ctype for users of crtdll.dll. * 04-06-92 KRS Changes for new ISO proposal. * 08-07-92 GJF Function calling type and variable type macros. * 10-26-92 GJF Fixed _pctype and _pwctype for crtdll. * 01-19-93 CFW Move to _NEWCTYPETABLE, remove switch. * 01-21-93 GJF Removed support for C6-386's _cdecl. * 02-17-93 CFW Removed incorrect UNDONE comment and unused code. * 02-18-93 CFW Clean up common _WCTYPE_DEFINED section. * 03-25-93 CFW _toupper\_tolower now defined when _INTL. * 03-30-93 CFW is* functions now use MB_CUR_MAX, MB_CUR_MAX defined. * 05-05-93 CFW Change is_wctype to iswctype as per ISO. * 06-26-93 CFW Remove is_wctype macro. * 10-14-93 SRW Add support for _CTYPE_DISABLE_MACROS symbol * ****/ #ifndef _INC_CTYPE #ifdef __cplusplus extern "C" { #endif #ifndef _INTERNAL_IFSTRIP_ #include #endif /* _INTERNAL_IFSTRIP_ */ /* * Conditional macro definition for function calling type and variable type * qualifiers. */ #if ( (_MSC_VER >= 800) && (_M_IX86 >= 300) ) /* * Definitions for MS C8-32 (386/486) compiler */ #define _CRTAPI1 __cdecl #define _CRTAPI2 __cdecl #else /* * Other compilers (e.g., MIPS) */ #define _CRTAPI1 #define _CRTAPI2 #endif #ifndef _WCHAR_T_DEFINED typedef unsigned short wchar_t;
