Is there a way in windows to know if a process is not responding?

Is there a way to know when a process is hung? is there a win32 call for this?

Just for other people passing by: It might be easier to use IsHungAppWindow.

You send it a WM_NULL with SendMessageTimeout(). If that times out after something like a second or three, it's not responding (though it might eventually, of course).
