DESCRIPTION

23       tickit_pen_bind_event() adds a new event handler to the  list  of  han‐
24       dlers  stored  by the pen, and returns an integer to identify this han‐
25       dler. This handler will be invoked for occurances of the event given by
26       the  ev argument. When invoked, func will be passed the pen instance, a
27       flags bitmask, a pointer to an event information structure  whose  type
28       depends on the event, and the user data pointer it was installed with.
29
30       tickit_pen_unbind_event_id() removes an event handler previously added,
31       by the identifier returned when it was  added,  invoking  it  with  the
32       TICKIT_EV_UNBIND flag if it was installed with TICKIT_BIND_UNBIND.

35       tickit_pen_bind_event()      returns     an     identifier     integer.
36       tickit_pen_unbind_event_id() returns no value.
