|
|
*Purpose:
|
|
* This file contains definitions and declarations for some commonly
|
|
* used constants, types, and variables.
|
|
* [ANSI]
|
|
*
|
|
* [Public]
|
|
*
|
|
*Revision History:
|
|
* 10-02-87 JCR Changed NULL definition #else to #elif (C || L || H)
|
|
* 12-11-87 JCR Added "_loadds" functionality
|
|
* 12-16-87 JCR Added threadid definition
|
|
* 12-18-87 JCR Added _FAR_ to declarations
|
|
* 02-10-88 JCR Cleaned up white space
|
|
* 08-19-88 GJF Revised to also work for the 386
|
|
* 05-03-89 JCR Added _INTERNAL_IFSTRIP for relinc usage
|
|
* 06-06-89 JCR 386: Made _threadid a function
|
|
* 08-01-89 GJF Cleanup, now specific to OS/2 2.0 (i.e., 386 flat
|
|
* model). Also added parens to *_errno definition
|
|
* (same as 11-14-88 change to CRT version).
|
|
* 10-30-89 GJF Fixed copyright
|
|
* 11-02-89 JCR Changed "DLL" to "_DLL"
|
|
* 03-02-90 GJF Added #ifndef _INC_STDDEF and #include <cruntime.h>
|
|
* stuff. Also, removed some (now) useless preprocessor
|
|
* directives.
|
|
* 04-10-90 GJF Replaced _cdecl with _VARTYPE1 or _CALLTYPE1, as
|
|
* appropriate.
|
|
* 08-16-90 SBM Made MTHREAD _errno return int *
|
|
* 10-09-90 GJF Changed return type of __threadid() to unsigned long *.
|
|
* 11-12-90 GJF Changed NULL to (void *)0.
|
|
* 02-11-91 GJF Added offsetof() macro.
|
|
* 02-12-91 GJF Only #define NULL if it isn't #define-d.
|
|
* 03-21-91 KRS Added wchar_t typedef, also in stdlib.h.
|
|
* 06-27-91 GJF Revised __threadid, added __threadhandle, both
|
|
* for Win32 [_WIN32_].
|
|
* 08-20-91 JCR C++ and ANSI naming
|
|
* 01-29-92 GJF Got rid of macro defining _threadhandle to be
|
|
* __threadhandle (no reason for the former name to be
|
|
* be defined).
|
|
* 08-05-92 GJF Function calling type and variable type macros.
|
|
* 01-21-93 GJF Removed support for C6-386's _cdecl.
|
|
* 04-06-93 SKS Replace _CRTAPI1/2 with __cdecl, _CRTVAR1 with nothing
|
|
* Remove support for OS/2, etc.
|
|
* 04-07-93 SKS Add _CRTIMP keyword for CRT DLL model
|
|
* Use link-time aliases for old names, not #define's
|
|
* 10-12-93 GJF Support NT and Cuda versions. Also, replace MTHREAD
|
|
* with _MT.
|
|
* 03-14-94 GJF Made declaration of errno match one in stdlib.h.
|
|
* 06-06-94 SKS Change if def(_MT) to if def(_MT) || def(_DLL)
|
|
* This will support single-thread apps using MSVCRT*.DLL
|
|
* 02-11-95 CFW Add _CRTBLD to avoid users getting wrong headers.
|
|
* 02-14-95 CFW Clean up Mac merge.
|
|
* 04-03-95 JCF Remove #ifdef _WIN32 around wchar_t.
|
|
* 12-14-95 JWM Add "#pragma once".
|
|
* 02-05-97 GJF Cleaned out obsolete support for _CRTAPI* and _NTSDK.
|
|
* Also, detab-ed
|
|
* 09-30-97 JWM Restored not-so-obsolete _CRTAPI1 support.
|
|
* 10-07-97 RDL Added IA64.
|
|
* 01-30-98 GJF Added appropriate defs for ptrdiff_t and offsetof
|
|
* 02-03-98 GJF Changes for Win64: added int_ptr and uint_ptr.
|
|
* 12-15-98 GJF Changes for 64-bit size_t.
|
|
* 05-13-99 PML Remove _CRTAPI1
|
|
* 05-17-99 PML Remove all Macintosh support.
|
|
* 10-06-99 PML Add _W64 modifier to types which are 32 bits in Win32,
|
|
* 64 bits in Win64.
