NAME

zmq_msg_more - 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);
}
