I'm using following code:
$inotify->watch ($watchdir, IN_ALL_EVENTS) or die "watch creat
+ion failed" ;
$0="cping: watch ready, waiting for activity (".scalar(localti
+me()).")...";
my @events = $inotify->read;
the line
$inotify->read; is blocking, which is nice, since it doesn't burn CPU when there is nothing to do.
But, now I need to run code, when there was no activity for longer then $timelimit;
I could switch to non-blocking calls, ie use something like this:
$inotify->blocking(0);
...
$inotify->read;
sleep 1s;
if ($idle>$timelimit) {
code();
};
but then my code starts burning CPU AND becomes less responsive ( blocking code has much better then a 1 second latency with reacting to activity in $watchdir ).
Is there any way out?
