Just as a pathfinder
I don't know nothing about the C++ bindings of zmq and how it is
implemented.
In C bindings you need to "pop" each part of the message in a variable
of your choice, then you can handle that variable as you do normal in
your language.
In C after receiving the message from your socket,
you do :
int msgsize = zmsg_size(receivedMessage);
byte *msgContent = zmsg_popmsg(receivedMessage);
then
for (int x = 0; i < msgsize; i++) {
doSomeThingWith(msgContent[i]);
}

Subject: Re: [zeromq-dev] How to receive byte array in ZeroMQ C++
Dear Mykola,
Thank you very much.
The message is defined in C# as follows:
var message = new ZMessage
{
new ZFrame(myByteArray)
};
publisher.Send(message);
I want to get the byte array in C++. May I use something like following:
zmq::message_t msg;
int rc = zmq_socket.recv(&msg);
if (rc)
{
unsigned char bytearray[] = msg.data();
}
Please check out following Pastebin links, to see publisher and subscriber code:

Thanks
Ravi

Hello Ravi,
If that's just a raw byte array, msg.data<uint8_t>() should to the trick. For
example:
for (size_t i = 0; i < msg.size(); ++i) {
printf("%02X ", msg.data<uint8_t>()[i]);
}
Regards,
Mykola
