// How to interface the driver:

// struct needed

typedef struct _MOUSEDATA {

	int	X; // either units to move or new position of X
	int	Y; // either units to move or new position of Y
	BYTE	ButtonStatus; // flag variable containing the button status

} MOUSEDATA;

// varibales needed

HANDLE hDevice;
MOUSEDATA MouseData = {320,240,0};
LPDWORD lpBytesReturned;
LPOVERLAPPED lpOverlapped;

// Load the driver dynamically

hDevice = CreateFile("\\\\.\\FMOUSE.VXD", 0, 0, NULL, OPEN_EXISTING,
                      0, 0);

// Post the mouse movements to the driver

DeviceIoControl(hDevice, WM_SETMOUSE, &MouseData, sizeof (MouseData),
		NULL, 0, lpBytesReturned, lpOverlapped);

MouseData.X = 10; // move 10 mickeys east
MouseData.Y = -5; // move 5 mickeys south

DeviceIoControl(hDevice, WM_MOVEMOUSE, &MouseData, sizeof (MouseData),
		NULL, 0, lpBytesReturned, lpOverlapped);
