*ehstate.h - exception handling state management declarations
|
|
*
|
|
* Copyright (c) 1993-1995, Microsoft Corporation. All rights reserved.
|
|
*
|
|
*Purpose:
|
|
* EH State management declarations. Does target-dependent definitions.
|
|
*
|
|
* Macros defined:
|
|
*
|
|
* GetCurrentState - determines current state (may call function)
|
|
* SetState - sets current state to specified value (may call function)
|
|
*
|
|
* [Internal]
|
|
*
|
|
*Revision History:
|
|
* 05-21-93 BS Module created.
|
|
* 03-03-94 TL Added Mips (_M_MRX000 >= 4000) changes
|
|
* 09-02-94 SKS This header file added.
|
|
* 09-13-94 GJF Merged in changes from/for DEC Alpha (from Al Doser,
|
|
* dated 6/20).
|
|
* 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".
