my $w;
my $cv = http_request GET => $url, ..., sub { $w = undef; callback(...
+) }; # kill the watcher when we're done
$w = AE::timer $timeout, 0, sub { $cv = undef }; # kill the http requ
+est after $timeout seconds
However, that may not work depending on what else you're doing - if you're waiting on $cv->recv, you may want to use $cv->send() if $cv inside the timer callback to trigger that.
Basically, start the request, then start the timer, then wait, and when the http request returns, clear the $cv variable and/or clear $w to terminate the timer. There are a few things to pay attention to here, to clear cv's and watchers at the appropriate time, but it should otherwise be straight forward. |
