alarm function under while loop

[Gokul Prasad]

Hi,

 Am setting "alarm" in calling a function to check if particular task
has executed properly or what.

when i place the below code under while loop this alarm function is
not being called, but when i comment while loop, it is just works fine
correctly.

while(end_time >= current_time){
$heap->{next_alarm_time} = int(time())+30;
                print STDERR "$heap->{next_alarm_time} why ti is printing\n";
             $kernel->alarm(next_task =>
$heap->{next_alarm_time});#$heap->{RESULT}->{event});
}
Not sure why it is happening? any suggestion.please
