title: RegisterRawInputDevices function usage
body: <p>I have several questions about <code>RegisterRawInputDevices()</code> function. I mean obviously it is for registering raw input device but the real question is how can I use that registered raw input device? </p>
  
  <p>Can I monitor <code>WM_INPUT</code> messages with this device? I couldn't find any examples.</p>
  
  <p>On MSDN every parameter of function is input parameter I didn't see any output parameter for monitoring.</p>
