[San-Diego-pm] A few questions of Perl

[Gautam Dey]

Alex,

  There are a few ways to do this. It is definitely doable in perl.
The hard way, is to use select and Socket or Socket::IO, with two
sockets open on to two different ports. You can then use one as a read
socket and another as a write socket.. However, if you do not want to
manage the run loop, where you are checking on select in a while(1)
look to see if there are any message, you can use POE
(http://search.cpan.org/dist/POE/) or something like AnyEvent
(http://search.cpan.org/~mlehmann/AnyEvent-5.22/lib/AnyEvent.pm) to
help you out. I'd recommend using POE or AnyEvent.

POE takes a bit to understand but was created for this very purpose.

Gautam.
