Waiting On Event - Time Out - Suspend

Posted by John W. on April 28, 2006
Hello Richard,

I was wondering about the following - and if it's possible to suspend in such a way as to make the task startup back at the beginning:

vTaskA(...){


for (;;)

vTaskSuspend(NULL); // 'normal' - gets resumed elsewhere

.
.do stuff
.
.
.
while ( event != event_complete ) {

if (timeout++ == TIME_OUT) {

vTaskSuspend(NULL)
}
}

.
.more stuff
.



} // end task


I guess the problem is that if a timeout occurs - more stuff gets done when the task is resumed - instead of do stuff getting done first.

I don't know if this is possible - but is there a way to suspend that will force the task to resume at the 'top' of the task?

Thanks!
John W.

How about, the task creates another copy of itself then deletes itself?

OK - I guess that could work.

Thanks,
