Re: Process id

[tachyon]

One way is to do a fork/exec which is all system really is anyway:

my $pid = fork ();
die "Fork failed!\n" unless defined $pid;
if ( $pid == 0 ) {
    # convert kid to java process
    exec( $path_to_java_process );
    exit 0;  # for clarity, we don't actually get here
}
# in the parent $pid holds PID of child which is (now) the java proces
+s

If you're going to be launching processes yourself, don't forget to reap them as well. If you want to catch errors on exit, you'll probably want to call wait or waitpid to do that.
