ZMQ_BIND

NAME

zmq_bind - accept incoming connections on a socket  

SYNOPSIS

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

DESCRIPTION

The zmq_bind() function binds the socket to a local endpoint and then accepts incoming connections on that endpoint.

The endpoint is a string consisting of a transport:// followed by an address. The transport specifies the underlying protocol to use. The address specifies the transport-specific address to bind to.

0MQ provides the the following transports:

tcp

unicast transport using TCP, see zmq_tcp(7)

ipc

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

inproc

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

pgm, epgm

reliable multicast transport using PGM, see zmq_pgm(7)

vmci

virtual machine communications interface (VMCI), see zmq_vmci(7)

Every 0MQ socket type except ZMQ_PAIR supports one-to-many and many-to-one semantics. The precise semantics depend on the socket type and are defined in zmq_socket(3).

The ipc, tcp and vmci transports accept wildcard addresses: see zmq_ipc(7), zmq_tcp(7) and zmq_vmci(7) for details.


Note

the address syntax may be different for zmq_bind() and zmq_connect() especially for the tcp, pgm and epgm transports.


Note

following a zmq_bind(), the socket enters a mute state unless or until at least one incoming or outgoing connection is made, at which point the socket enters a ready state. In the mute state, the socket blocks or drops messages according to the socket type, as defined in zmq_socket(3). By contrast, following a libzmq:zmq_connect[3], the socket enters the ready state.

 

RETURN VALUE

The zmq_bind() function returns zero if successful. Otherwise it returns -1 and sets 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);
