Re: alarm function under while loop

Hi,

To give more context on the issue, the following lines are not
working(alarm function is being called ) but later runs fine

NOT WORKING!!!!! (recursive call thro alarm)
------------------------
delete_sub(){
  .
  .
  .
  .

 if($heap->{RESULT}->{delete_sub_status} ne 'deleted'){
        $heap->{next_delete_alarm_time} = int(time())+30;
#                $_[KERNEL]->alarm(get_del_status =>
$heap->{next_delete_alarm_time}) if($end_time >= time);

                $_[KERNEL]->alarm(delete_sub =>
$heap->{next_delete_alarm_time}) if($end_time >= time);
                $heap->{RESULT}->{delete_sub_status_counter}++;
        }

}


WORKING!!!(recursive call thro alarm)
------------------
get_poll_status(){
  .
 .
  .
        if($heap->{RESULT}->{poll_success} != 1){
     #   while($end_time >= time){
                $heap->{next_poll_alarm_time} = int(time())+30;
                $_[KERNEL]->alarm(get_poll_status =>
$heap->{next_poll_alarm_time})  if($end_time >= time);
                $heap->{RESULT}->{poll_status_error_counter}++;
      #  }
        }else{
        $_[KERNEL]->yield("get_delivery_status",$pollquerystring);
        }

}
Please let me know if am missing something in it!!, it works at one
stage not at other, as i told, i couldnt get it running with
run_while() function, googling didnt gave me much info nor poe
cookbook.
