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 linkzmq:zmq_tcp[7] +'ipc':: local inter-process communication transport, see linkzmq:zmq_ipc[7] +'inproc':: local in-process (inter-thread) communication transport, see linkzmq:zmq_inproc[7] +'pgm', 'epgm':: reliable multicast transport using PGM, see linkzmq:zmq_pgm[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 +linkzmq:zmq_socket[3]. + +The 'ipc' and 'tcp' transports accept wildcard addresses: see linkzmq:zmq_ipc[7] +and linkzmq:zmq_tcp[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 linkzmq: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); +---- + + +SEE ALSO +-------- +linkzmq:zmq_connect[3] +linkzmq:zmq_socket[3] +linkzmq:zmq[7] + + +AUTHORS +------- +This 0MQ manual page was written by Pieter Hintjens <ph@imatix.com>, +Martin Sustrik <sustrik@250bpm.com> and Martin Lucina <mato@kotelna.sk>. |
