( #3333=superdoc: print w/replies, xml ) Need Help??

I even modified the server code to make it working, i removed the gui portion. Now when i am starting the server and then starting the client from another terminal , it works. However, the first time when I start, it prints msg1, then stops. Again when i start , it prints msg1 amd msg2. Similarly third time msg1, msg2,msg3 .

My question is

1. why not all the five messages msg1..msg5 are getting printed in one go when i start

The client code remains as it is as posted before
Can someone please explain me the flow of the code.

my $server; $server = IO::Socket::INET::->new( Proto => 'tcp', LocalPort => 55555, Listen => 1, Reuse => 1 ) or die "Server can't start: $!"; my $readable_handles = new IO::Select(); my $buf; while (my $client = $server->accept) { #Infinite loop # select() blocks until a socket is ready to be read or written my ($new_readable) = IO::Select->select($readable_handles, undef, undef, 0); # print "Inside while \n"; # If it comes here, there is at least one handle # to read from or write to. For the moment, worry only about # the read side. $readable_handles->add($client); foreach my $sock (@$new_readable) { if ($sock == $server) { my $new_sock = $sock->accept(); # Add it to the list, and go back to select because the # new socket may not be readable yet. $readable_handles->add($new_sock); } else { # It is an ordinary client socket, ready for reading. $buf = <$sock>; if ($buf) { # .... Do stuff with $buf #$$status_ref = $buf; print $buf ; } else { # Client closed socket. We do the same here, and remov +e # it from the readable_handles list $readable_handles->remove($sock); #close($sock); } } } }
