/***
*stdarg.h - defines ANSI-style macros for variable argument functions * * Copyright (c) 1985-2001, Microsoft Corporation. All rights reserved. * *Purpose: * This file defines ANSI-style macros for accessing arguments * of functions which take a variable number of arguments. * [ANSI] * * [Public] * *Revision History: * 05-03-89 JCR Added _INTERNAL_IFSTRIP for relinc usage * 08-15-89 GJF Cleanup, now specific to OS/2 2.0 (i.e., 386 flat model) * 10-30-89 GJF Fixed copyright * 11-02-89 JCR Changed "DLL" to "_DLL" * 01-05-90 JCR Added NULL definition * 03-02-90 GJF Added #ifndef _INC_STDARG stuff. Also, removed some * (now) useless preprocessor directives. * 05-29-90 GJF Replaced sizeof() with _INTSIZEOF() and revised the * va_arg() macro (fixes PTM 60) * 05-31-90 GJF Revised va_end() macro (propagated 5-25-90 change to * crt7 version by WAJ) * 10-30-90 GJF Moved the real definitions into cruntime.h (for NT * folks) and relinc.sed (to release ANSI compatible * version). Ugly compromise. * 08-20-91 JCR C++ and ANSI naming * 11-01-91 GDP MIPS Compiler support. Moved real definitions back here * 10-16-92 SKS Replaced "#ifdef i386" with "#ifdef _M_IX86". * 11-03-92 GJF Fixed several conditionals, dropped _DOSX32_ support. * 01-03-93 SRW Fold in ALPHA changes * 01-09-93 SRW Remove usage of MIPS and ALPHA to conform to ANSI * Use _MIPS_ and _ALPHA_ instead. * 01-25-93 GJF Fix va_list definition. * 10-04-93 SRW Fix ifdefs for MIPS and ALPHA to only check for _M_?????? defines * 10-12-93 GJF Merged NT version into Cuda version. Also, replaced * _ALPHA_ with _M_ALPHA. * 11-11-93 GJF Minor cosmetic changes. * 04-05-94 SKS Add prototype of __builtin_va_start for ALPHA * 10-02-94 BWT Add PPC support. * 11-03-94 GJF Ensure 8 byte alignment. * 12-28-94 JCF Merged with mac header. * 02-11-95 CFW Add _CRTBLD to avoid users getting wrong headers. * 02-14-95 CFW Clean up Mac merge. * 12-14-95 JWM Add "#pragma once". * 02-24-97 GJF Detab-ed. * 10-07-97 RDL Added IA64. * 11-07-97 RDL Soft23 definitions. * 02-06-98 GJF Changes for Win64: fixed _APALIGN() macro (fix from * Intel) * 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. * 10-25-99 PML Add support for _M_CEE (VS7#54572). * 01-20-00 PML Remove __epcg__. * 05-17-00 PML Use __alignof in _APALIGN macro for IA64. * 09-07-00 PML Remove va_list definition for _M_CEE (vs7#159777) * 09-21-00 PML Change IA64 definition of va_start for C++ (vs7#103357) * 02-05-01 PML Fix va_start for classes with operator& (vs7#201535) * 03-19-01 BWT Add AMD64 changes * 03-26-01 GB Added va_args for AMD64 * 07-15-01 PML Remove all ALPHA, MIPS, and PPC code * ****/
