是否可以在MFC应用程序的调试版本中替换内存分配器? [英] Is it possible to replace the memory allocator in a debug build of an MFC application?

问题描述

我想在其中的电子围栏中使用MFC应用程序.我想跟踪new/delete，如果我可以跟踪malloc/free，那将是一个额外的奖励.

I'd like to make use of Electric Fence in an MFC application. I'd like to track new/ delete, and if I can track malloc/ free that's an added bonus.

不幸的是，MFC重新定义了new和delete-但是使用了宏(DEBUG_NEW)-因此我无法使用重新定义它们的标准C ++方法. (MFC将它们定义为具有不同的签名，并将源文件和行号作为附加参数).

Unfortunately, MFC redefines new and delete - but using macros (DEBUG_NEW) - so I can't use the standard C++ method of redefining them. (MFC defines them to have different signatures, with source file and line numbers as additional parameters).

有没有办法强制所有new/delete通过我的分配器，并停止MFC尝试获取这些分配器?

Is there any way to force all new/ deletes to go via my allocator, and stop MFC trying to grab these allocators?

推荐答案

您可以通过在stdafx.h末尾重新定义DEBUG_NEW来停止MFC对new的钩住.

You can stop the MFC hooking of new by redefining DEBUG_NEW in the end of stdafx.h

#undef DEBUG_NEW
#define DEBUG_NEW new
