/*** *cruntime.h - definitions specific to the target operating system and hardware * * Copyright (c) 1990-2001, Microsoft Corporation. All rights reserved. * *Purpose: * This header file contains widely used definitions specific to the * host operating system and hardware. It is included by every C source * and most every other header file. * * [Internal] * *Revision History: * 02-27-90 GJF File created * 03-06-90 GJF Added register macros (REG1,...,etc.) * 04-11-90 GJF Set _CALLTYPE1 and _CALLTYPE4 to _stdcall. * 10-30-90 GJF Added macros defining variable args interface. * 10-31-90 GJF Added definition of _JBLEN (from setjmp.h). * 11-13-90 GJF Revised #ifdef-s, now use symbolic constants * representing target OS and target processor, with * #error directives for unsupported targets. Note the * general grouping of only OS-dependent definitions * followed by OS and processor dependent definitions. * 02-25-91 SRW Move _JBLEN definition back to setjmp.h [_WIN32_] * 04-09-91 PNT Added _MAC_ definitions * 05-09-91 GJF Restored _JBLEN definitions. Also fixed the macros * defining the target processor so both Stevewo's stuff * and mine would work. * 05-13-91 GJF Changed _CALLTYPE1 and _CALLTYPE4 to _cdecl for * Cruiser (_CRUISER_). * 08-28-91 JCR ANSI keywords * 11-01-91 GDP _JBLEN back to setjmp.h, stdarg macros back to stdarg.h * 03-30-92 DJM POSIX support. * 08-07-92 GJF Revised various macros. * 09-08-92 GJF Restored definition of _MIPS_ (temporarily). * 11-09-92 GJF Revised preprocessing conditionals for MIPS. * 01-09-93 SRW Remove usage of MIPS and ALPHA to conform to ANSI * Use _MIPS_ and _ALPHA_ instead. * 02-01-93 GJF Removed support for C6-386. * 04-06-93 SKS Remove support for OS/2, MAC, POSIX, MIPS, etc. * 11-11-93 GJF Merged in NT SDK version. Note that having * definitions for the variable-argument access macros * in this file is probably obsolete - this needs to be * checked. * 10-02-94 BWT Add PPC support. * 10-09-94 BWT Unknown platform changes from John Morgan. * 12-15-94 XY merged with mac header * 02-14-95 CFW Clean up Mac merge. * 03-29-95 CFW Add error message to internal headers. * 12-14-95 JWM Add "#pragma once". * 02-24-97 GJF Detab-ed. * 10-07-97 RDL Added IA64. * 05-17-99 PML Remove all Macintosh support. * 11-03-99 PML Remove _VA_LIST_T * 03-18-01 PML Define _USE_OLD_STDCPP when compiling with stdcpp64 * and stdhpp64, for the Win64 system CRTs. * 07-15-01 PML Remove all ALPHA, MIPS, and PPC code * ****/ #if _MSC_VER > 1000 /*IFSTRIP=IGN*/ #pragma once #endif #ifndef _INC_CRUNTIME #define _INC_CRUNTIME #ifndef _CRTBLD /* * This is an internal C runtime header file.
