Hello,

Thanks for your response. Can you give me an example of how to use fork to start a function in a perl module in the background?

Thank you.

    if (my $pid = fork) { # parent ($pid is process id of child) parent_function(); } else { # child child_function(); exit; }
    Feel free to read perldoc -f fork, and look at some examples online. This is not really advanced perl, but it requires some attention.
      From personal experience, the exit is key. Let's just say that I'm glad that I had my own Sun workstation when I started experimenting with fork...*cough*fork bomb*cough*

      Hello, Remember to check for a fork error after forking:
      if (my $pid = fork) { ## Parent } elsif ($pid == 0) { ## Child } else { ## Error, $pid is undefined }
