/***
*crtdbg.h - Supports debugging features of the C runtime library.
*
* Copyright (c) 1994-2001, Microsoft Corporation. All rights reserved.
*
*Purpose:
* Support CRT debugging features.
*
* [Public]
*
*Revision History:
* 08-16-94 CFW Module created.
* 11-28-94 CFW Add DumpClient, more params for AllocHook.
* 12-08-94 CFW Use non-win32 names.
* 01-09-95 CFW Dump client needs size, add _CrtSetBreakAlloc,
* use const state pointers.
* 01-10-95 CFW dbgint.h merge.
* 01-20-94 CFW Change unsigned chars to chars.
* 01-24-94 CFW Cleanup: remove unneeded funcs, add _CrtSetDbgFlag.
* 01-24-94 CFW _CrtDbgReport now returns 1 for debug.
* 02-11-95 CFW Add _CRTBLD to avoid users getting wrong headers.
* 02-14-95 CFW Clean up Mac merge.
* 02-17-95 CFW new() proto moved from dbgint.h.
* 02-27-95 CFW Change debug break scheme.
* 03-21-95 CFW Add _CRT_ASSERT & _delete_client, remove tracking.
* 03-23-95 JWM Restored tracking.
* 03-28-95 CFW Remove tracking, export _crtBreakAlloc.
* 04-06-95 CFW Add malloc -> _malloc_dbg macros.
* 04-10-95 CFW Define NULL.
* 03-21-95 CFW Remove _delete_client.
* 03-30-95 CFW Avoid _CRTDBG_xxx conflicts with MFC.
* 05-11-95 CFW Move C++ code to its own section.
* 05-12-95 CFW Use _CrtIsValidPointer & _CrtIsValidHeapPointer.
* 06-08-95 CFW Add return value parameter to report hook.
* 06-27-95 CFW Add win32s support for debug libs.
* 07-25-95 CFW Add win32s support for user visible debug heap variables.
* 09-01-95 GJF Moved a proto for new up slightly to avoid compiler
* error C2660 (Olympus 1015).
* 09-20-95 CFW Change _RPT0, _RPTF0 to support messages with '%' in them.
* 12-14-95 JWM Add "#pragma once".
* 01-23-97 GJF Cleaned out obsolete support for Win32s.
* 04-21-97 JWM Added 4-parameter operator delete(), required by 6.0 compiler.
* 04-29-97 JWM Made 4-parameter operator delete() #if _MSC_VER >= 1200.
* 08-14-97 GJF Strip __p_* prototypes from release version. Also,
* moved the constant and type definition out of the ifdef
* _DEBUG so they are always defined.
* 01-19-98 JWM At request of DeanM, made debug prototypes of new & delete
* #ifndef _MFC_OVERRIDES_NEW
* 05-22-98 JWM Added support for new[] & delete[], courtesy of KFrei's RTC work.
* 06-08-98 JWM Minor cleanups.
* 12-01-98 GJF More choices for calling _CrtCheckMemory than never or always.
* 12-15-98 GJF Changes for 64-bit size_t.
* 05-17-99 PML Remove all Macintosh support.
* 08-30-99 PML Get rid of unprintable character in comment.
* 10-06-99 PML Add _W64 modifier to types which are 32 bits in Win32,
* 64 bits in Win64.
* 11-02-99 PML Add extern "C++" around C++ definitions.
* 11-08-99 PML Don't mark debug operator new _CRTIMP (vs7#16060).
* 11-16-99 PML Forward-decl _CrtMemBlockHeader to work around vs7#63059
* 01-04-00 GB Added support for debug version for _aligned routines
* 02-25-00 PML _CrtDbgBreak should use __debugbreak if available.
* 05-31-00 PML Add _CrtReportBlockType (VS7#55049).
* 09-26-00 PML Fix _ASSERT*, _RPT* to compile /W4 clean (vs7#166894)
* 12-10-00 PML Non-_DEBUG macro versions of _CrtSet* should not be
* typed as void (vs7#166572).
* 03-21-01 PML Add _CrtSetReportHook2 (vs7#124998)
