I am developing Airlib, and now I need to create a window using WinAPI wihtout any main() or WinMain or anything like that in C (not cpp). So far whatever I find is in C++ or uses WinMain. I think SDL uses OpenGL, but I'd like to do without.

The way I register for raw input is

RAWINPUTDEVICE Rid[2];

//    //rawinputdevice for mouse
	Rid[0].usUsagePage = 0x01;
    Rid[0].usUsage = 0x02;
    Rid[0].dwFlags = RIDEV_NOLEGACY;
    Rid[0].hwndTarget = 0;
//
//    //rawinputdevice for keyboard
    Rid[1].usUsagePage = 0x01;
    Rid[1].usUsage…

@21st Century Moose This is the problem… I can't check the HRESULT from the Present() because the program stops WHILE making the Present (I checked this by putting the execution on Pause to see where the principal Thread stopped, and that's how I knew that it was the Present() that made all crash.)…

Thanks for pointing that out. It has since been fixed.  ?

There are quite a few strings available. Perhaps you want HidD_GetPhysicalDescriptor()?
