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 linkzmq:zmq_inproc[7]
|
|
'ipc':: local inter-process communication transport, see linkzmq:zmq_ipc[7]
|
|
'tcp':: unicast transport using TCP, see linkzmq:zmq_tcp[7]
|
|
'pgm', 'epgm':: reliable multicast transport using PGM, see linkzmq: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 linkzmq: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);
