I am using libzmq and setting up topics using binary data. In other words, my
topic is the first 2 bytes of my message.
I subscribe by setting a and b to the values I'm interested in:
for (uint16_t i = a; i <= b; i++)
{
d = zmq_setsockopt(sub_socket, ZMQ_SUBSCRIBE, &i, 2);
if (d)
{
printf ("E: subscription failed: %s\n", strerror
(errno));
return -1;
}
}
My publisher publishes like this:
string incoming_string = " this message";
incoming_string.insert(0,1,i>>8);
incoming_string.insert(0,1,i%256);
int rc = zmq_send(pub_socket, incoming_string.c_str(),
incoming_string.size(), 0);
I can't seem to subscribe to more than 1000 topics (values 0x0000 - 0x03e7).
From what I understand, thousands of topics should be available.
Any guidance would be helpful.
Thanks,
Benjy
