A parent can fork as many times as it wants to (for that matter a child
could fork as well). So your code would look like this:
$SIG{CHLD} = "IGNORE"; #works on unix platforms, auto reaps children
foreach $machine (get_machines()) {
$pid = fork;
if ($pid == 0) { #I am a child
check_machine($machine);
} elsif (not $pid) {
#if parent then $pid = process id, if error then
#$pid = undef
error();
}
}
