[Tutor] sockets

[Praveen Pathiyil]

Hi,
        There is a select module which gives you the asynchronous behaviour.
The select call returns the socket descriptor on which there is any data to
be read. Calling this in a separate thread could do the job. Hence if you
want to do some processing while you wait for the data to arrive, you can
use the select call.

        If you would like to take a look at more code which does similar
things, there is a page about the Medusa project. This was referred to me by
Danny when i was doing some stuff on telnet server. It really bailed me out
on a couple of occasions.

Praveen.
