IO::Socket and IO:Select problem

Hi!
I'm programming a chatserver in perl. Over the same socket different chatters are to receive the output.
Therefore I'm using IO::Socket and IO:Select. But until now I do only have a quite complicated way to send output to a certain chatter
...
my $listen = IO::Socket::INET->new(Proto => 'tcp',
                           LocalPort => 2323,
                           Listen => 1,
                           Reuse => 1) or die $!;
my $select = IO::Select->new($listen);
...
   for $socket ($select->handles) {
      if (($socket->fileno) == 5)   ### in this case only socket-connection
                                      ### with fileno = 5 should receive $outputstuff
           {$socket->send($outputstuff);}
}
...

Is there a command to send data directly to one certain socket-fileno without running a loop over all available socket-connections?
Thanx a lot!

Simple, brute force solution.  As you're opening sockets, assign a reference to the socket to a hash based on the fileno...

i.e.

my(%FileNos);
.

$FileNos{$socket->fileno} = \$socket;
..


Later, then, you can just do:

$FileNos{5}->send($outputstuff);

OK, that works just fine. If there's a way to access sockets by fileno directly please feel free to add a comment.
