Unloading from EndScene hook

[nerexis]

I have question about unloading a injected dll while using endscene hook. How to unload it in safe way, because using DetourDetach makes wow window dissapear due to error probably because my hooked endscene is executing and it's unloading in the same time.

I was detaching hooked function in DLL_PROCESS_DETACH.

Don't use DLL_PROCESS_DETACH.
Create a new thread, use some kind on synchronization to make sure it waits until your endscene hook is done, unhook, call FreeLibraryAndExitThread function

For example:

EndSceneHook()
{
  if(!TryEnterCriticalSection(&g_framelock))
    return; // something else is using the framelock. exit function.

  // do stuff..

  LeaveCriticalSection(&g_framelock);
}

UnloadDLLFunc() // called from a new thread
{
  EnterCriticalSection(&g_framelock); // call blocks until framelock aquired. ie. it's guaranteed to not be in endscene
  // [unhook code]
  DeleteCriticalSection(&g_framelock);

  FreeLibraryAndExitThread(dllhandle, 0);
}

Works! Thank you.
