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 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);
