A proxy that identifies the event tap posting the event. Your event tap callback function is passed this proxy when it is invoked.
The event to post.
You can use this function to post a new event at the same point to which an event returned from an event tap callback function would be posted. The new event enters the system before the event returned by the callback enters the system. Events posted into the system will be seen by all taps placed after the tap posting the event.
