zmq_bind

NAME

zmq_bind - assign a local address to a socket

SYNOPSIS

int zmq_bind (void *socket, const char *address);

DESCRIPTION

The zmq_bind() function shall assign a local address specified by the address argument to the socket referenced by the socket argument.

The address argument is a string consisting of two parts as follows: transport://endpoint. The transport part specifies the underlying transport protocol to use. The meaning of the endpoint part is specific to the underlying transport protocol selected.

The following transports are defined:

tcp

unicast transport using TCP, see zmq_tcp(7)

pgm, epgm

reliable multicast transport using PGM, see zmq_pgm(7)

ipc

local inter-process communication transport, see zmq_ipc(7)

inproc

local in-process (inter-thread) communication transport, see zmq_inproc(7)

A single socket may have an arbitrary number of local addresses assigned to it using zmq_bind(), while also being connected to an arbitrary number of peer addresses using zmq_connect().

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 given address is already in use.

EADDRNOTAVAIL

A nonexistent interface was requested or the requested address was not local.

EXAMPLE

Example 1. 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 endpoint '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);
