This manual page describes how the ØMQ C++ language binding maps to the underlying ØMQ C library functions.
All ØMQ constants defined by zmq.h are also available to the C++ language binding.
The following classes are provided in the zmq namespace:
The context_t class encapsulates functionality dealing with the initialisation and termination of a ØMQ context.
Maps to the zmq_init() function, as described in zmq_init(3).
Maps to the zmq_term() function, as described in zmq_term(3).
None.
The socket_t class encapsulates a ØMQ socket.
Maps to the zmq_socket() function, as described in zmq_socket(3).
Calls the zmq_close() function, as described in zmq_close(3).
Maps to the zmq_setsockopt() function, as described in zmq_setsockopt(3).
Maps to the zmq_bind() function, as described in zmq_bind(3).
Maps to the zmq_connect() function, as described in zmq_connect(3).
Maps to the zmq_send() function, as described in zmq_send(3).
Maps to the zmq_recv() function, as described in zmq_recv(3).
The zmq::message_t class encapsulates the zmq_msg_t structure and functions to construct, destruct and manipulate ØMQ messages.
These map to the zmq_msg_init(), zmq_msg_init_size() and zmq_msg_init_data() functions, described in zmq_msg_init(3), zmq_msg_init_size(3) and linkzmq_msg_init_data[3] respectively.
Calls the zmq_msg_close() function, as described in zmq_msg_close(3).
Maps to the zmq_msg_data() function, as described in zmq_msg_data(3).
Maps to the zmq_msg_size() function, as described in zmq_msg_size(3).
Maps to the zmq_msg_copy() function, as described in zmq_msg_copy(3).
Maps to the zmq_msg_move() function, as described in zmq_msg_move(3).
Equivalent to calling the zmq_msg_close() function followed by the corresponding zmq_msg_init() function.
The poll() function is a namespaced equivalent of the zmq_poll() function, as described in zmq_poll(3).
All errors reported by the underlying ØMQ C library functions are automatically converted to exceptions by the C++ language binding. The zmq::error_t class is derived from the std::exception class and uses the zmq_strerror() function to convert the error code to human-readable string.
zmq::context_t ctx (1, 1); zmq::socket_t s (ctx, ZMQ_PUB); s.connect ("tcp://192.168.0.115:5555"); zmq::message_t msg (100); memset (msg.data (), 0, 100); s.send (msg);
