Cancel all pending instances of after event Event.
This built-in predicate is obsolete!
All instances of the pending after event Event is
cancelled so that the event will not be triggered. A pending after event
is an event which is setup by either event_after/2, event_after/3 or
event_after_every/2, and which is waiting to be raised
(event_after_every/2 will always be pending as it is raised repeatedly).
Note that the processing of an already raised, but as yet unprocessed
event will not be cancelled by this predicate.
This is equivalent to

- (5) type error
- Event is not an atom.
