NAME¶
zmq_bind - accept connections on a socketSYNOPSIS¶
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: inproclocal 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¶
EINVALThe 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);
