ZMQ_BIND(3) 0MQ Manual ZMQ_BIND(3) NAME
zmq_bind - accept connections on a socket SYNOPSIS
int zmq_bind (void *socket, const char *endpoint); DESCRIPTION
The zmq_bind() function shall create an endpoint for accepting connections and bind it to the socket referenced by the socket argument. The endpoint argument is a string consisting of two parts as follows: transport://address. The transport part specifies the underlying transport protocol to use. The meaning of the address part is specific to the underlying transport protocol selected. The following transports are defined: inproc local in-process (inter-thread) communication transport, see zmq_inproc(7) ipc local inter-process communication transport, see zmq_ipc(7) tcp unicast transport using TCP, see zmq_tcp(7) pgm, epgm reliable multicast transport using PGM, see zmq_pgm(7) With the exception of ZMQ_PAIR sockets, a single socket may be connected to multiple endpoints using zmq_connect(), while simultaneously accepting incoming connections from multiple endpoints bound to the socket using zmq_bind(). Refer to zmq_socket(3) for a description of the exact semantics involved when connecting or binding a socket to multiple endpoints. RETURN VALUE
The zmq_bind() function shall return zero if successful. Otherwise it shall return -1 and set errno to one of the values defined below. ERRORS
EINVAL The endpoint supplied is invalid. EPROTONOSUPPORT The requested transport protocol is not supported. ENOCOMPATPROTO The requested transport protocol is not compatible with the socket type. EADDRINUSE The requested address is already in use. EADDRNOTAVAIL The requested address was not local. ENODEV The requested address specifies a nonexistent interface. ETERM The 0MQ context associated with the specified socket was terminated. ENOTSOCK The provided socket was invalid. EMTHREAD No I/O thread is available to accomplish the task. EXAMPLE
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); SEE ALSO
