Interestingly enough, this just showed up on perlmonks this morning.

Simultaneous alarms under 1 sec

Above is your problem. You are assigning the NUMBER of elements in @_ to
$waittime, not the first element. Use one of the following:
my $waittime = shift;
my ($waittime) = @_;
my $waittime = $_[0];
>$ppid = getppid();

or what you need.

Hello,
I have aquestions.
If I need an alarm signal alarm(), in less than 1 second what can I do?
Would that work?
sub selfalarm {
$waittime = @_;
if ($pid = fork){
} else {
$ppid = getppid();
select (undef,undef,undef, $waittime);
kill 14 => ppid;
}
}
SIG{ALRM} = su
