Pieter Hintjens 67e02ca8bc Use of named authors on man pages is no longer a good idea since it puts off
contributors and doesn't reflect the real process. I've taken out all named
authors and referred to the contribution policy. Hopefully this will improve
the contributions to the man pages.

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);
}
