DLL卸载本身 [英] DLL unloading itself

问题描述

DLL内部的函数是否可以卸载DLL？我需要这样做，所以我可以确保DLL没有被使用，然后写入DLL的文件。

Is it possible for a function that is inside a DLL to unload the DLL? I need to do this so I can make sure the DLL is not in use, then write to the DLL's file.

推荐答案

我不要以为会奏效使用外部的句柄调用FreeLibrary（LoadLibrary将从DLL外部的区域调用），因为代码在不再有效的内存位置运行。

I don't think it will work. Calling FreeLibrary with a handle from the outside (LoadLibrary would have been called from an area outside the DLL) as the code runs in a memory location that will not be valid anymore.

即使这样可能，它闻起来像一个糟糕的设计。也许你想做一些更新或一样。说明一下你期望的结果。从内部卸载DLL是不行的。

Even if this is possible, it smells like a bad design. Maybe you want to make some updater or alike. Explain a bit more what is the result you expect. Unloading a DLL from within itself is not the way to go.
