Re: shutdown( ) blocks forever

Hi,

Thanks. A couple of more questions:
a) Could you help me with a sample code which handles shutdown gracefully
(async shutdown + timer) for iterative servers?
b) I have also seen issues where the code hangs just like the shutdown()
when I invoke socket_.lowest_layer().cancel(). Is this expected?
c) Is this what is the code to be put in the async shutdown handler?
     socket_.lowest_layer().close(ignored_ec);

Regards,
Fariya
