Yes, that is correct.
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;
}
...
}
I get the general intent of your code - and I tried it out without
success - I don't quite understand the two uses of 'alarm' - why does it
need to be in the sub and before the while loop? Also when the wakeup
sub finishes where does the program return to? Also I added a
$SIG{ALRM} to trap the alarm and execute the sub - was that the intent
of your code or is there an easier way of doing it?
My apologies if I seem a little slow on the uptake. :)
Many Thanks
