[zeromq-dev] How to receive byte array in ZeroMQ C++

[Ravi Joshi]

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:

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
