zmq_msg_set_routing_id - set routing ID property on message
int zmq_msg_set_routing_id (zmq_msg_t *message, uint32_t routing_id);
The zmq_msg_set_routing_id() function sets the routing_id specified, on the the message pointed to by the message argument. The routing_id must be greater than zero. To get a valid routing ID, you must receive a message from a ZMQ_SERVER socket, and use the libzmq:zmq_msg_routing_id method. Routing IDs are transient.
The zmq_msg_set_routing_id() function shall return zero if successful. Otherwise it shall return -1 and set errno to one of the values defined below.
EINVAL
