[rtl] dynamic periodic task ?

[Kay-Ulrich Scholl <scholl@fzi.de>]

Hi,

I created a periodic task but the period-time changes
from time to time.
The tak decides on his own when he wants to be recalled again.
At the moment I do this in the following way:

 RTIME wait=last_send+wait_time-rt_get_time()-CAN_SEND_PERIOD;
 // should I wait longer than CAN_SEND_PERIOD ?
 if (wait>0)
 {
     long flags;
     r_save_flags(flags);
     r_cli();
     // wait a litle bit longer next time:
     can_send_task.resume_time=rt_get_time()+wait;
     r_restore_flags(flags);
 }
 rt_task_wait();

Is there a better way ?
