如何确定一个 dll 是否已经注册到我的 c++ function？

Question

A newbie question-

I want to write a wrapper function in windows c++ which will look into some input parameters passed and based on whether an associated dll is registered or not would respond to the application.

So basically i need to

1)register dlls with my wrapper fn 2)the wrapper should scan through the registered dlls

what is the best way to do this?? where to start?

I'm not sure what you mean by register - are we talking about COM registration or your own custom registration system?

In any case, once you know what DLLs to load, use LoadLibrary to load the DLL into memory, and GetProcAddress to get pointers to exported functions from the DLL. If you're doing a plugin-style thing, you'll probably want to call an initialization function in the DLL, and allow the DLL to do any setup it may need to register itself with your application.
