Overriding or changing the ExitProcess function in C++
Is there any way that I can override or change the ExitProcess function in C++ that when I call the function it will go to my code?
I thought about taking the address of the function and putting my function in there but I can't realize how to do that?
any suggestion to how can I do that?

You have std::atexit.
I just tried this and it works, at least for normal program terminations:
void at_exit_handler() {
MessageBox(NULL, L"Howdy", L"Howdy", MB_OK);
}
// register the exit function at program start:
std::atexit(at_exit_handler);
If you want to intercept the ExitProcess call and prevent the normal exit procedure you perhaps need to take a look at Debug Hook Function Writing.

this doesn't work with ExitProcess and I meant to replace the ExitProcess function with my function so the process wont exit.
