schedule-timer-relative-milliseconds timer
relative-expiration-time &optional repeat-time => timer
The
schedule-timer-relative-milliseconds
function schedules a timer to expire at a given time after the call to the function. The
timer
argument is a timer returned by make-timer or make-named-timer. The
relative-expiration-time
argument is a non-negative real number of milliseconds after the call to the function at which the timer is to expire. If
repeat-time
is specified, it is a non-negative real number of milliseconds that specifies a repeat interval. Each time the timer expires, it is rescheduled to expire after this repeat interval.
If the timer is already scheduled to expire at the time this function is called, it is rescheduled to expire at the time specified by the
relative-expiration-time
argument. If that argument is
nil
, the timer is not rescheduled, but the repeat interval is set to the interval specified by the
repeat-time
argument.
The function schedule-timer-milliseconds schedules a timer to expire at a time relative to the start of the program.
The following example schedules a timer to expire 5 seconds after the call to
schedule-timer-relative-milliseconds
and every 5 seconds thereafter.
(setq timer
(mp:make-timer 'print 10 *standard-output*))
#<Time Event : PRINT>
(mp:schedule-timer-relative-milliseconds timer 5000
5000)
#<Time Event : PRINT>
