DLL的新增/删除是否覆盖用户代码new / delete？ [英] Does DLL new/delete override the user code new/delete?

问题描述

guys，
如果我覆盖全局新和删除我的dll代码，这将覆盖用户代码新和删除？
我做了一个测试，它显示用户新和删除不会受到影响。
如果我想让用户代码为新的，删除被替换为mine sdk new / delete，那么怎么做。

guys, If I override the global new and delete in my dll code, will this override the user code new and delete? I made a test, and it shows the user new and delete will not be impacted. If I want to make user code new and delete be replaced by mine sdk new/delete, how to do that.

模板类的情况是什么。模板类定义包括一些新的/删除。用户代码可以实例化它。那么，它可能使用用户新的/删除，对吗？

What's the case of template class. Template class definition includes some new/delete. And user code might instantiate it. Then, it might use user new/delete, right?

推荐答案

不，在Windows上每个DLL都有自己的 operator new（） / operator delete（）。但是你应该小心 - 如果一些DLL new s对象应该 delete d使用相同的 operator delete（） - 否则会遇到未定义的行为。

No, on Windows each DLL has its own operator new()/operator delete(). However you should be careful - if some DLL news an object that object should be deleted using the same operator delete() - otherwise you run into undefined behavior.
