PublicShow sourcetime.pl -- Time and alarm library

Source alarm(+Time, :Callable, -Id) is det
Source alarm(+Time, :Callable, -Id, +Options) is det
Set up an alarm to be signaled Time seconds from now. If the alarm expires, Callable is called asynchronously. Callable can be used to raise an exception using throw/1 to abort some execution.

Options is a list of Name(Value) options. Currently defined options are:

remove(Bool)
If true (default false), remove the alarm-event (as remove_alarm/1) after it has been fired.
install(Bool)
If false (default true) do not install the alarm. It must be installed separately using install_alarm/1.
Source alarm_at(+Time, :Callable, -Id) is det
Source alarm_at(+Time, :Callable, -Id, +Options) is det
As alarm/3 and alarm/4, but schedule the alarm at an absolute point in time.
See also
- date_time_stamp/2.
Source install_alarm(+Id) is det
Source install_alarm(+Id, +RelTime) is det
Install an alarm allocated using alarm/4 with the install(false) option or de-activated using uninstall_alarm/1. With a given RelTime, the alarm is scheduled at the RelTime from now. Otherwise it is scheduled on the same (absolute) time on which is was created.
Source uninstall_alarm(+Id) is det
De-activate an alarm. This does not invalidate Id, but ensures that the alarm will not fire. The alarm can be rescheduled to the original time using install_alarm/1 or to a new time using install_alarm/2.
Source remove_alarm(+Id) is det
Remove an alarm. If it has not yet been fired, it never will.
Source current_alarm(?Time, :Goal, ?Id, ?Status) is nondet
Enumerate the alarms in the schedule. Time is the absolute time the event is scheduled for (see also get_time/1). Goal is the goal to execute, Id is the identifier and Status is the scheduling status. It takes the value done if the alarm has been fired, next if the event is the next to be executed and scheduled otherwise.
Source call_with_time_limit(+Time, :Goal) is semidet
Call Goal, while watching out for a (wall-time) limit. If this limit is exceeded, the exception time_limit_exceeded is raised. Goal is called as in once/1.
throws
- time_limit_exceeded
