   How to use PointToClient() to get mouse position?
  HeyI'm getting raw mouse data: Input::Obj().Mouse_x = Input::Obj().raw->data.mouse.lLastX;Input::Obj().Mouse_y = Input::Obj().raw->data.mouse.lLastY;Input::Obj().MouseKeyDown = Input::Obj().raw->data.mouse.ulButtons & RI_MOUSE_LEFT_BUTTON_DOWN;However these values: Mouse_x and Mouse_y need interpreting to get the real positions of mouse. I've read that I can do this with function: PointToClient(), however I have no idea how to use it and can't find it anywhere... Moreover my program event doesn't recognize this function. What library is this function from? What header should I add?Maybe there are other ways of interpreting raw mouse positions? I will be very grateful for help!To sump up I'm using Windows API and Visual C++ and the question is how to get interpreted mouse coords from raw input?
