The zmq_bind() function binds the socket to a local endpoint and then accepts incoming connections on that endpoint.
The endpoint is a string consisting of a transport:// followed by an address. The transport specifies the underlying protocol to use. The address specifies the transport-specific address to bind to.
0MQ provides the the following transports:
Every 0MQ socket type except ZMQ_PAIR and ZMQ_CHANNEL supports one-to-many and many-to-one semantics. The precise semantics depend on the socket type and are defined in zmq_socket(3).
the address syntax may be different for zmq_bind() and zmq_connect() especially for the tcp, pgm and epgm transports.
following a zmq_bind(), the socket enters a mute state unless or until at least one incoming or outgoing connection is made, at which point the socket enters a ready state. In the mute state, the socket blocks or drops messages according to the socket type, as defined in zmq_socket(3). By contrast, following a libzmq:zmq_connect, the socket enters the ready state.
Binding a publisher socket to an in-process and a TCP transport.
/* Create a ZMQ_PUB socket */ void *socket = zmq_socket (context, ZMQ_PUB); assert (socket); /* Bind it to a in-process transport with the address 'my_publisher' */ int rc = zmq_bind (socket, "inproc://my_publisher"); assert (rc == 0); /* Bind it to a TCP transport on port 5555 of the 'eth0' interface */ rc = zmq_bind (socket, "tcp://eth0:5555"); assert (rc == 0);
