Re: POE::Component::Server::TCP - accessing listener heap entries

Hi, Krishna.

Sorry that the docs aren't clear.  It's all Perl, so you could say:

my $server_heap;

POE::Component::Server::TCP->new(
  ...,
  Started => sub { $server_heap = $_[HEAP] },
);

... and then access the server's heap from $server_heap via closure.  Be careful to avoid circular references when you work like this, and you should be fine.
