NAME

6       zmq_msg_more - indicate if there are more message parts to receive
7

SYNOPSIS

9       int zmq_msg_more (zmq_msg_t *message);
10

DESCRIPTION

12       The zmq_msg_more() function indicates whether this is part of a
13       multi-part message, and there are further parts to receive. This method
14       can safely be called after zmq_msg_close(). This method is identical to
15       zmq_msg_get() with an argument of ZMQ_MORE.
16

RETURN VALUE

18       The zmq_msg_more() function shall return zero if this is the final part
19       of a multi-part message, or the only part of a single-part message. It
20       shall return 1 if there are further parts to receive.
21

EXAMPLE

23       Receiving a multi-part message.
24
25           zmq_msg_t part;
26           while (true) {
27               //  Create an empty 0MQ message to hold the message part
28               int rc = zmq_msg_init (&part);
29               assert (rc == 0);
30               //  Block until a message is available to be received from socket
31               rc = zmq_msg_recv (socket, &part, 0);
32               assert (rc != -1);
33               if (zmq_msg_more (&part))
34                   fprintf (stderr, "more\n");
35               else {
36                   fprintf (stderr, "end\n");
37                   break;
38               }
39               zmq_msg_close (&part);
40           }
