in thread Timeout for an established connection

How to do it? Check each socket? Suppose, there is 1000 sockets. Poll said that two of them are available to read. During 0.2 seconds, will be available for 2 more. You say every time check the other 998?

    my $index = $#noreply +1; push @noreply, $obj = HTTP_Request->new($ip, $packet, sub { delete $noreply[$index]; .............. }); .............. .............. my $check_time = time(); my $timeout = 30; while (1) { $poll->poll(5); for my $sock ( $poll->handles( POLLHUP | POLLERR | POLLNVAL )) { $sock->error(); } for my $sock ( $poll->handles(POLLIN) ) { $sock->recv(); } for my $sock ($poll->handles(POLLOUT)) { $sock->send(); } if (time > ($check_time + $timeout)) { $check_time = time; my $i; foreach (@noreply) { if ($_ && $_->ttl < $check_time) { delete $noreply[$i]; $_->close; } ++$i; } } }
    Maybe someone has a more elegant solution?

      If you willing to switch to AnyEvent, then AnyEvent::Handle allows you to set inactivity timeouts for reading and writing just as you want.

      Also, calling delete on array values is deprecated. I'd suggest something like:

      @noreply = grep { $_ && $_->ttl >= $check_time } @noreply;
