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);
