Subject: [9fans] dial and time out
Date: Thu, 10 Sep 2009 11:32:28 +0200	[thread overview]
Message-ID: <e48ca67a55a6fbe6504fa8cfc08117e3@smgl.fr.eu.org> (raw)

Hello 9fans,

I have a bunch of threads, simply scheduled with yield() at the moment
(I'll use alt later on), and each of them is calling dial() at some
point. I don't want the other threads to wait for "too long" when one
of them is blocked on a dial() that will eventually time out.
 So I was thinking, for each of them, of creating a proc which would
be used as a timer; it would be created just before the call to dial,
wait for some time, and then kill the dial()ing thread. And as mechiel
suggested, the dial()ing thread would also be set to kill the timer
after it successfully dialed, hence not being killed if it was fast
enough.

Is that the right way to go? If yes, can anyone think of an already
existing example I can look at?

Mathieu
