# `current_event/5`

## Description

    current_event(Event, Object, Message, Sender, Monitor)

Enumerates, by backtracking, all defined events. The two types of events are represented by the atoms `before` and `after`.

## Modes and number of proofs

    current_event(?event, ?term, ?term, ?term, ?object_identifier) - zero_or_more

## Errors

`Event` is neither a variable nor a valid event identifier:
`type_error(event, Event)`
`Object` is neither a variable nor a valid object identifier:
`type_error(object_identifier, Object)`
`Message` is neither a variable nor a callable term:
`type_error(callable, Message)`
`Sender` is neither a variable nor a valid object identifier:
`type_error(object_identifier, Sender)`
`Monitor` is neither a variable nor a valid object identifier:
`type_error(object_identifier, Monitor)`

## Examples

    % enumerate all events monitored by the "debugger" object:
    | ?- current_event(Event, Object, Message, Sender, debugger).
