unless ($pid) {
if (!defined($pid)) {
system_logger("Unable to fork: $!");
die "fork: $!"; # or just exit as you were
}
# note that in this test, $pid is undefined,
# which means we're the child thread, so no
# matter what happens, we must exec or exit/die

}
is (the use of 'TERM' in kill) a product of the English module, or built in?
It's built-in.
Hope this helps. |
