Hi, everyone
On PUB side: wd is struct type message and I send it to the subscriber.
typedef struct tag_StructData
{
string name;
}StructData;
StructData wd;
// Prepare our context and publisher
zmq::context_t context (1);
zmq::socket_t publisher (context, ZMQ_PUB);
int msgSize = sizeof(wd);
zmq::message_t message(msgSize);
memcpy ((void *) message.data(), &wd, msgSize);
publisher.send(message);
On SUB side:
// Receive Everything
subscriber.setsockopt(ZMQ_SUBSCRIBE, NULL, 0);
// How to set a filter to receive the struct message with the specified name,
for example "ABC".
//string msg;
StructData *msg;
while(true){
zmq::message_t m;
subscriber.recv(&m);
msg = (StructData *)m.data();
cout << msg->Symbol << endl;
}
Thanks.
