Documentation examples for zmq_msg_get and zmq_msg_more functions have an incorrect call to zmq_msg_close function - with 'zmq_msg_t' as a parameter despite 'zmq_msg_t *' is required, so it is impossible to compile these examples properly. Also for zmq_msg_get example - declaration of zmq_msg_t variable is added (like it is done in other examples).

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);
|
|
}
