zmq_bind(3)

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

-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 ØMQ context associated with the specified socket was terminated. -
-
-EFAULT -: -
-The provided socket was not valid (NULL). -
-

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);
