clientserver.c

//  Create server and client sockets and connect over inproc
zsock_t *server = zsock_new_server ("@inproc://zframe-server.test");
zsock_t *client = zsock_new_client (">inproc://zframe-server.test");

//  Send message from client to server
zframe_t frame = zframe_new ("Hello", 5);
int rc = zframe_send (&frame, client, 0);

//  Read message
frame = zframe_recv (server);
zframe_t *reply_frame = zframe_new("Reply", 5);
rc = zframe_send_reply(&reply_frame, frame, server, 0);
zframe_destroy(&frame);

//  Read reply
frame = zframe_recv (client);
zframe_destroy(&frame);

zsock_destroy (&client);
