Performing a double click using CGEventCreateMouseEvent()

I'm using the following code to simulate a click of the mouse:

void PostMouseEvent(CGMouseButton button, CGEventType type, const CGPoint point) 
{
 CGEventRef theEvent = CGEventCreateMouseEvent(NULL, type, point, button);
 CGEventSetType(theEvent, type);
 CGEventPost(kCGHIDEventTap, theEvent);
 CFRelease(theEvent);
}

void LeftClick(const CGPoint point) 
{
 PostMouseEvent(kCGMouseButtonLeft, kCGEventMouseMoved, point);
 NSLog(@"Click!");
 PostMouseEvent(kCGMouseButtonLeft, kCGEventLeftMouseDown, point);
 PostMouseEvent(kCGMouseButtonLeft, kCGEventLeftMouseUp, point);
}

I can use basically the same code to do a control-click (right click) by changing:

kCGEventLeftMouseDown

kCGEventLeftMouseUp

kCGMouseButtonLeft

to their respective "Right" events. The function looks something like:

void RightClick(const CGPoint point) 
{
 PostMouseEvent(kCGMouseButtonRight, kCGEventMouseMoved, point);
 NSLog(@"Click Right");
 PostMouseEvent(kCGMouseButtonRight, kCGEventRightMouseDown, point);
 PostMouseEvent(kCGMouseButtonRight, kCGEventRightMouseUp, point);
}

But, how about a double click? I tried sending 2 leftclicks and calling PostMouseEvent() twice in a row but no luck. How do you perform a double click?

thanks!
