It works fine with unknown functions. Just use a unique constant instead of function pointer.

any example for C hooking CreateFileMapping, OpenFileMapping and MapViewOfFile ?

For quick, Copilot can help you.

https://copilot.microsoft.com/sl/iGq8ESNUtWu (OpenFileMapping and MapViewOfFile)

Note: Not tested. But give a try and update a little bit if error.

thanks copilot, will do my way with vs2010 minhook compatible.

But for copilot we need paid or a credit card to be added? That is not so safe since the Microsoft can then identify us if they need.

No. It's fully free. No required anything that related to privacy.

Do you have a company or student subscription?

It is only free for verified students, teachers, and maintainers of popular open source projects.

Ah no. I'm talking about Microsoft's Copilot. Not GitHub's Copilot. 😁

Ok... Even the microsoft copilot requires login using microsoft account but at least that can be faked!
By faking, I mean creating a fake microsoft login account which does not have your real name in the email id, etc.

Perhaps. What cannot be faked is knowledge. Such as the fact that you can download code from github, train your own LLM and run inference on it to achieve a similar result. You see? You learn something new everyday. Granted training requires a high amount of computational and memory resources.
