    CGPoint newloc;
    CGEventRef eventRef;
    newloc.x = x;
    newloc.y = y;

    eventRef = CGEventCreateMouseEvent(NULL, kCGEventMouseMoved, newloc,
                                        kCGMouseButtonCenter);
    //Apparently, a bug in xcode requires this next line
    CGEventSetType(eventRef, kCGEventMouseMoved);
    CGEventPost(kCGSessionEventTap, eventRef);
    CFRelease(eventRef);

    return 0;
}
