man zmq_msg_more (3): indicate if there are more message parts to receive

SYNOPSIS

int zmq_msg_more (zmq_msg_t *message);

DESCRIPTION

The zmq_msg_more() function indicates whether this is part of a multi-part message, and there are further parts to receive.

RETURN VALUE

The zmq_msg_more() function shall return zero if this is the final part of a multi-part message, or the only part of a single-part message. It shall return 1 if there are further parts to receive.

EXAMPLE

Receiving a multi-part message.

zmq_msg_t part;
while (true) {
    //  Create an empty 0MQ message to hold the message part
    int rc = zmq_msg_init (&part);
    assert (rc == 0);
    //  Block until a message is available to be received from socket
    rc = zmq_recvmsg (socket, &part, 0);
    assert (rc != -1);
    if (zmq_msg_more (&part))
        fprintf (stderr, "more\n");
    else {
        fprintf (stderr, "end\n");
        break;
    }
    zmq_msg_close (part);
}
