zmq: Publish / Subscribe problem

gistfile1.cpp

//Publisher
int zipcode, temperature, relhumidity;

//  Get values that will fool the boss
zipcode     = 10001;
temperature = 1;
relhumidity = 2;

//  Send message to all subscribers
zmq::message_t topic(6);

memcpy ((void *) topic.data (), "NASDAQ", 6);
publisher.send(topic, ZMQ_SNDMORE);

zmq::message_t message(20);
snprintf ((char *) message.data(), 20 ,
	"%05d %d %d", zipcode, temperature, relhumidity);
publisher.send(message);


//Subscriber
const char *filter = "NASDAQ";¬                                                                                                                                                                                                           
subscriber.setsockopt(ZMQ_SUBSCRIBE, filter, strlen (filter));
zmq::message_t topic_message;
subscriber.recv(&topic_message);
char* topic = static_cast<char*>(topic_message.data());
std::cout << topic << std::endl;

zmq::message_t body_message;
subscriber.recv(&body_message);
char* body = static_cast<char*>(body_message.data());
std::cout << body << std::endl;


//Prints
NASDAQ1 2
10001 1 2

Instead of
NASDAQ
10001 1 2
