RTEMS Ada User's Guide

8.4.10: TIMER_RESET - Reset an interval timer

CALLING SEQUENCE:

procedure Timer_Reset (
   ID     : in     RTEMS.ID;
   Result :    out RTEMS.Status_Codes
);

DIRECTIVE STATUS CODES:

RTEMS.SUCCESSFUL - timer reset successfully
RTEMS.INVALID_ID - invalid timer id
RTEMS.NOT_DEFINED - attempted to reset a when or newly created timer

DESCRIPTION:

This directive resets the timer associated with id. This timer must have been previously initiated with either the rtems.timer_fire_after or rtems.timer_server_fire_after directive. If active the timer is canceled, after which the timer is reinitiated using the same interval and timer service routine which the original rtems.timer_fire_after rtems.timer_server_fire_after directive used.

NOTES:

If the timer has not been used or the last usage of this timer was by a rtems.timer_fire_when or rtems.timer_server_fire_when directive, then the RTEMS.NOT_DEFINED error is returned.

Restarting a cancelled after timer results in the timer being reinitiated with its previous timer service routine and interval.

This directive will not cause the running task to be preempted.
