title: Generating Mouse events in C++ / Processing on Windows (Emulate Mouse)
body: <p>I have a proprietary device connected via An arduino microprocessor to USB, which I want to use as a Mouse emulator. At present I use a processing (language) program to generate x,y data pertaining to mouse coordinates. </p>
  
  <p>I'm looking for a way to emulate the mouse, so that a application such as a game which uses the mouse pointer can be used with my system, without altering the application.</p>
  
  <p>I think this deals with Windows APIs ?. It is more like I want to know where I can find reference if I want to write a program which works as a mouse driver.</p>
