{ Event taps.

   A function registers an event tap, taking a pointer to the program's tap
   function and an arbitrary reference to be passed to the tap function, and
   returning a `CFMachPortRef' the program can add to the appropriate run
   loop by creating a surce and using `CFRunLoopAddSource'.

   Taps may be placed at the point where HIDSystem events enter the server,
   at the point where HIDSystem and remote control events enter a session,
   at the point where events have been annotated to flow to a specific
   application, or at the point where events are delivered to the
   application. Taps may be inserted at a specified point at the head of
   pre-existing filters, or appended after any pre-existing filters.

   Taps may be passive event listeners, or active filters. An active filter
   may pass an event through unmodified, modify an event, or discard an
   event. When a tap is registered, it identifies the set of events to be
   observed with a mask, and indicates if it is a passive or active event
   filter. Multiple event type bitmasks may be "OR"ed together.

   Taps may only be placed at `kCGHIDEventTap' by a process running as the
   root user. NULL is returned for other users.

   Taps placed at `kCGHIDEventTap', `kCGSessionEventTap',
   `kCGAnnotatedSessionEventTap', or on a specific process may only receive
   key up and down events if access for assistive devices is enabled
   (Preferences Universal Access panel, Keyboard view) or the caller is
   enabled for assistive device access, as by `AXMakeProcessTrusted'. If the
   tap is not permitted to monitor these events when the tap is created,
   then the appropriate bits in the mask are cleared. If that results in an
   empty mask, then NULL is returned.

   Releasing the CFMachPortRef will release the tap.

   A `CGEventTapProxy' is an opaque reference to state within the client
   application associated with the tap. The tap function may pass this
   reference to other functions, such as the event-posting routines.

   The event tap callback runs from the CFRunLoop to which the tap
   CFMachPort is added as a source. Thread safety is defined by the
   CFRunLoop and its environment. }

   tap may be re-enabled by calling this function. }

   enters the system. Events posted into the system will be seen by all taps

{ Gets a list of currently installed event taps.

   `tapList' is an array of event tap information structures of length
   `maxNumberOfTaps'. You are responsible for allocating storage for this
   array. On return, your array contains a list of currently installed event
   taps. On return, the number of event taps that are currently installed is
   stored in `eventTapCount'. If you pass NULL in this parameter, the
   `maxNumberOfTaps' parameter is ignored, and the number of event taps that
   are currently installed is stored in `eventTapCount'.

   Each call to this function has the side effect of resetting the minimum
   and maximum latencies in the `tapList' parameter to the corresponding
   average values. Values reported in these fields reflect the minimum and
   maximum values seen since the preceding call, or the instantiation of the
   tap. This allows a monitoring tool to evaluate the best and worst case
   latency over time and under various operating conditions. }
