/***
*dbgint.h - Supports debugging features of the C runtime library.
*
* Copyright (c) 1985-2001, Microsoft Corporation. All rights reserved.
*
*Purpose:
* Support CRT debugging features.
*
* [Internal]
*
*Revision History:
* 08-16-94 CFW Module created.
* 11-28-94 CFW Add DumpClient.
* 12-05-94 CFW Fix debug new handler support, clean up macros.
* 12-06-94 CFW Export _CrtThrowMemoryException.
* 12-08-94 CFW Export _assertfailed.
* 01-05-95 CFW Asserts are errors, add report hook.
* 01-05-95 CFW Filename pointers are const.
* 01-10-95 CFW Lots moved to crtdbg.h
* 01-11-95 CFW Add _xxxx_crt macros.
* 01-13-95 CFW Add new() support.
* 01-20-94 CFW Change unsigned chars to chars.
* 02-14-95 CFW Clean up Mac merge.
* 02-17-95 CFW new() proto moved to crtdbg.h.
* 03-21-95 CFW Add _delete_crt.
* 03-29-95 CFW Add error message to internal headers.
* 03-21-95 CFW Remove _delete_crt, add _BLOCK_TYPE_IS_VALID.
* 06-27-95 CFW Add win32s support for debug libs.
* 12-14-95 JWM Add "#pragma once".
* 04-17-96 JWM Make _CrtSetDbgBlockType() _CRTIMP (for msvcirtd.dll).
* 02-05-97 GJF Removed use of obsolete DLL_FOR_WIN32S.
* 01-04-00 GB Added support for debug version of _aligned routines.
* 08-25-00 PML Reverse _CrtMemBlockHeader fields nDataSize and
* nBlockUse on Win64 so size % 16 == 0 (vs7#153113).
