*excpt.h - defines exception values, types and routines
|
|
*
|
|
* Copyright (c) 1990-2001, Microsoft Corporation. All rights reserved.
|
|
*
|
|
*Purpose:
|
|
* This file contains the definitions and prototypes for the compiler-
|
|
* dependent intrinsics, support functions and keywords which implement
|
|
* the structured exception handling extensions.
|
|
*
|
|
* [Public]
|
|
*
|
|
*Revision History:
|
|
* 11-01-91 GJF Module created. Basically a synthesis of except.h
|
|
* and excpt.h and intended as a replacement for
|
|
* both.
|
|
* 12-13-91 GJF Fixed build for Win32.
|
|
* 05-05-92 SRW C8 wants C6 style names for now.
|
|
* 07-20-92 SRW Moved from winxcpt.h to excpt.h
|
|
* 08-06-92 GJF Function calling type and variable type macros. Also
|
|
* revised compiler/target processor macro usage.
|
|
* 11-09-92 GJF Fixed preprocessing conditionals for MIPS. Also,
|
|
* fixed some compiler warning (fix from/for RichardS).
|
|
* 01-03-93 SRW Fold in ALPHA changes
|
|
* 01-04-93 SRW Add leave keyword for x86
|
|
* 01-09-93 SRW Remove usage of MIPS and ALPHA to conform to ANSI
|
|
* Use _MIPS_ and _ALPHA_ instead.
|
|
* 01-21-93 GJF Removed support for C6-386's _cdecl.
|
|
* 02-18-93 GJF Changed _try to __try, etc.
|
|
* 03-31-93 CFW Removed #define try, except, leave, finally for x86.
|
|
* 04-06-93 SKS Replace _CRTAPI1/2 with __cdecl, _CRTVAR1 with nothing
|
|
* 07-29-93 GJF Added declarations for _First_FPE_Indx and _Num_FPE.
|
|
* 09-01-93 GJF Merged Cuda and NT SDK versions.
|
|
* 10-04-93 SRW Fix ifdefs for MIPS and ALPHA to only check for _M_??????
|
|
* defines
|
|
* 10-12-93 GJF Merged again.
|
|
* 10-19-93 GJF MS/MIPS compiler gets most of the same SEH defs and
|
|
* decls as the MS compiler for the X86.
|
|
* 10-29-93 GJF Don't #define try, et al, when compiling C++ app!
|
|
* 12-09-93 GJF Alpha compiler now has MS front-end and implements
|
|
* the same SEH names.
|
|
* 11-03-94 GJF Ensure 8 byte alignment.
|
|
* 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".
|
|
* 02-21-97 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.
|
|
* 11-12-97 RDL __C_specific_handler() prototype change from SC.
|
|
* 05-13-99 PML Remove _CRTAPI1
|
|
* 05-17-99 PML Remove all Macintosh support.
|
|
* 06-13-01 PML Compile clean -Za -W4 -Tc (vs7#267063)
|
|
* 07-15-01 PML Remove all ALPHA, MIPS, and PPC code
|
