ZMQ_MSG_ROUTING_ID(3) 0MQ Manual ZMQ_MSG_ROUTING_ID(3)

zmq_msg_routing_id - return routing ID for message, if any

uint32_t zmq_msg_routing_id (zmq_msg_t *message);

The zmq_msg_routing_id() function returns the routing ID for the message, if any. The routing ID is set on all messages received from a ZMQ_SERVER socket. To send a message to a ZMQ_SERVER socket you must set the routing ID of a connected ZMQ_CLIENT peer. Routing IDs are transient.

The zmq_msg_routing_id() function shall return zero if there is no routing ID, otherwise it shall return an unsigned 32-bit integer greater than zero.

Receiving a client message and routing ID.
void *ctx = zmq_ctx_new ();
assert (ctx);
void *server = zmq_socket (ctx, ZMQ_SERVER); assert (server); int rc = zmq_bind (server, "tcp://127.0.0.1:8080"); assert (rc == 0);
zmq_msg_t message; rc = zmq_msg_init (&message); assert (rc == 0);
// Receive a message from socket rc = zmq_msg_recv (server, &message, 0); assert (rc != -1); uint32_t routing_id = zmq_msg_routing_id (&message); assert (routing_id);
