Hi All, I added server and client sockets support to CZMQ, you can take a look at the change at the following pull request:
https://github.com/zeromq/czmq/pull/1059 Server socket is like router socket except you don't have an identity frame, each message also include routing id which is an int (vs byte array). So each message coming from a server socket include a routing id which can be retrieve by calling zframe_routing_id. When sending a message you must set the routing id by calling zframe_set_routing_id. You can use zframe_send_reply with both the destination frame and the source frame (which include the routing id), the method copy the routing id from the source frame to the destination frame and then send the message. Client socket is same as dealer socket. Client and Server can only talk to each other. Following is a small example on how to use the new client and server sockets: https://gist.github.com/somdoron/542b74922f652d229566 Client and server socket are thread safe (currently only support single frame messages but that might change, I think) so if your protocol is single frame you can use the server and client sockets from multiple threads. Polling on multiple client or server sockets is not supported yet. In the coming week I plan to also add zproto support and complete the polling on multiple sockets. Doron
