+zmq_msg_more(3)
+===============
+
+
+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. This method can safely be
+called after _zmq_msg_close()_. This method is identical to _zmq_msg_get()_
+with an argument of ZMQ_MORE.
+
+
+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_msg_recv (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);
+}
