*setjmp.h - definitions/declarations for setjmp/longjmp routines
|
|
*
|
|
* Copyright (c) 1985-1996, Microsoft Corporation. All rights reserved.
|
|
*
|
|
*Purpose:
|
|
* This file defines the machine-dependent buffer used by
|
|
* setjmp/longjmp to save and restore the program state, and
|
|
* declarations for those routines.
|
|
* [ANSI/System V]
|
|
*
|
|
* The setjmp() that will be used by those who include this file
|
|
* is _setjmpex, which is safe for use with try/except/finally,
|
|
* but is slow. See <crt/setjmpex.h> and <crt/setjmp.h> for more.
