Hi all,

I need to send Status of a child to parent and from that, parent will decide to kill the child or give it some time. Here is my code: 


sub function2 {
    my $pid = @_;
    print "END\n";
    exit 0;
}

for my $count (1..3){
        my $child_pid = fork();
        print "PID: $child_pid \n";
        if ($child_pid) {  # If I have a child PID, then I must be the
+ parent
                push @children_pids, $child_pid;
        }
        else { # I am the child
                my $end;
                local $SIG{HUP} = sub { $end = 1 };
                my $Child_PID = $$;
                print "CHILD's PID is: $Child_PID \n";
                #my $wait_time = int(rand(30));
                my $wait_time = 30;
                # NEED TO SEND THE STATUS SIGNAL TO PARENT  
                my $localtime = localtime;
                #Write to DB
               until ($end) {
                  print "Sleep 1\n";
                  sleep 1;
               }
               function2($Child_PID);
        }
}


print "\n ----- Main DB ---- \n";
foreach my $child (@children_pids) {
        print "Parent: Waiting on $child\n";
        my $localtime = localtime;
        sleep 5;
        print "Killing child: $child \n";
        kill HUP => $child;
        waitpid($child, 0);
}


print "All done.\n";
