I am still rather new to POE, but I am charging ahead and attempting to write a tool I need using it, but I am having an issue with communication that I am sure someone can assist with.
I started with the code here: http://poe.perl.org/?POE_Cookbook/TCP_Servers- the "Using Socket Factory and ReadWrite" example at the bottom. The server code, once modified seems to be doing most of what I need, as clients can connect, and I can properly respond to events coming down the line from clients. In place of the 'echo back anything the client sends you' I am examining the data, and responding to it with what I need and all seems to be well. The problem is that I have one client that connects that sends me data that I need to make sure reaches the other clients so that they can process the data arriving. I can accept and process the data from this master client, but I cannot find how I might send the data to each running process to in turn have their sessions react to the data arriving. Since it is a client session just like any other that is receiving the data, even saving down the session IDs into a hash I am having an issue sending data across to the other sessions. Perhaps this just means that I am going about this wrong. Using the example code above, here is an example of how I am trying to implement this: sub socket_input { my ($heap, $buf) = @_[HEAP, ARG0]; $buf =~ s/[\r\n]//gs; #Pseudocode here to explain - not actual code. if ($buf =~ m/matchcriteria/g) { send_to_all_clients($buf); }; } This really just means that I need to not just process what arrives, but be able to make other sessions process what arrives from the master client. Do I have to build a session that is not a normal client, and bind that port manually to make sure that it is high enough in the hierarchy to send to all of the users using their session ID? No matter how much I have read on the topic, I am having difficulty understanding how I might accomplish this. The only other issue, is that I would like to be able to call a function for each client to occasionally check local variables to make decisions on what to do. As it sits now, the clients are purely driven by the data arriving in the port - they examine arriving data, then do something. I would like to add a function to have the clients regularly check a variable for data to determine if they need to initiate a send to the connected remote user. Thank you all for any information you can provide. -Ty Roden
