// This file shows how to use the Controller Input SDK to get
// both positional and descriptive information about the controller
// such as:
// - DIJOYSTATE2 for corresponding controller
// - XINPUT_STATE for corresponding controller
// - connection status (general or based on controller type or
//   controller model)
// - XInput or DirectInput
// - friendly name
// - Vendor ID (VID)
// - Product ID (PID)
// - has force feedback/rumble or not
// - device handle
// - XInput ID

// NOTE: This file can't compile. Therefore it hasn't been tested and
// there may be some errors.
