   /* Create a new message, allocating 6 bytes for message content */

zmq_msg_t msg;

int rc = zmq_msg_init_size (&msg, 6);

assert (rc == 0);

/* Fill in message content with 'AAAAAA' */

memset (zmq_msg_data (&msg), 'A', 6);

/* Send the message to the socket */

rc = zmq_msg_send (&msg, socket, 0);

assert (rc == 6);

.Sending a multi-part message

----

/* Send a multi-part message consisting of three parts to socket */

rc = zmq_msg_send (&part1, socket, ZMQ_SNDMORE);

rc = zmq_msg_send (&part2, socket, ZMQ_SNDMORE);

/* Final part; no more parts to follow */

rc = zmq_msg_send (&part3, socket, 0);
