OK, this sounds like an ideal application of threads. I don't have much
experience with them, so I'll leave it to others to tell you how to use
them.
But if your Perl wasn't compiled with threads:
First, read `perldoc perlipc`.
I assume your mainline is waiting on input. Like:
while( <> ){
...
}
If you use alarm, then these waits will be interrupted by the alarm. So
you need a flag to indicate this:
my $alarmed = 0;
sub wakeup {
$alarmed = 1;
# the rest of wakeup
alarm( 600 );
}
...
alarm( 600 );
while( <> ){
if( $alarmed ){
$alarmed = 0;
next;
}
...
}
