i wrote a while script as part of a huge program. this script, once picked, begins to output data to the person using it. pretty easy, as the person doesn't have to keep typing commands to get the output that the while loop automatically throws out.
now, the thing is, while this while-script... (3 Replies)

Mail::SpamAssassin::Timeout(3pm) User Contributed Perl Documentation Mail::SpamAssassin::Timeout(3pm)NAME
Mail::SpamAssassin::Timeout - safe, reliable timeouts in perl
SYNOPSIS
# non-timeout code...
my $t = Mail::SpamAssassin::Timeout->new({ secs => 5, deadline => $when });
$t->run(sub {
# code to run with a 5-second timeout...
});
if ($t->timed_out()) {
# do something...
}
# more non-timeout code...
DESCRIPTION
This module provides a safe, reliable and clean API to provide alarm(2)-based timeouts for perl code.
Note that $SIG{ALRM} is used to provide the timeout, so this will not interrupt out-of-control regular expression matches.
Nested timeouts are supported.
PUBLIC METHODS
my $t = Mail::SpamAssassin::Timeout->new({ ... options ... });
Constructor. Options include:
secs => $seconds
time interval, in seconds. Optional; if neither "secs" nor "deadline" is specified, no timeouts will be applied.
deadline => $unix_timestamp
Unix timestamp (seconds since epoch) when a timeout is reached in the latest. Optional; if neither secs nor deadline is specified,
no timeouts will be applied. If both are specified, the shorter interval of the two prevails.
$t->run($coderef)
Run a code reference within the currently-defined timeout.
The timeout is as defined by the secs and deadline parameters to the constructor.
Returns whatever the subroutine returns, or "undef" on timeout. If the timer times out, "$t-<gt"timed_out()> will return 1.
Time elapsed is not cumulative; multiple runs of "run" will restart the timeout from scratch. On the other hand, nested timers do
observe outer timeouts if they are shorter, resignalling a timeout to the level which established them, i.e. code running under an
inner timer can not exceed the time limit established by an outer timer. When restarting an outer timer on return, elapsed time of a
running code is taken into account.
$t->run_and_catch($coderef)
Run a code reference, as per "$t-<gt"run()>, but also catching any "die()" calls within the code reference.
Returns "undef" if no "die()" call was executed and $@ was unset, or the value of $@ if it was set. (The timeout event doesn't count
as a "die()".)
$t->timed_out()
Returns 1 if the most recent code executed in "run()" timed out, or "undef" if it did not.
$t->reset()
If called within a "run()" code reference, causes the current alarm timer to be restored to its original setting (useful after our
alarm setting was clobbered by some underlying module).
