Hey, I have a basic question on perl Fork. Once I start child process, I need the parent process to perform some action till the child process ends. I have tried using "until(waitpid)" but that doesnt work. Could someone help me out. Thanks! Here is the code.. 

FORK: {
    if ($pid=fork) {  ## parent process,no operation is performed here
    next;
    } elsif (defined $pid) {  ## Starting Fork, transfering data
         &download_a_file();
         exit 0;
    }
} 

until (waitpid ($pid,0) ) { 
## I need to perform some action only when child process is running
    &calculate_network_bandwidth();
}
