ZMQ_BIND(3) 0MQ Manual ZMQ_BIND(3)NAMEzmq_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);
