The 0MQ lightweight messaging kernel is a library which extends the
standard socket interfaces with features traditionally provided by
specialised messaging middleware products. 0MQ sockets provide an
abstraction of asynchronous message queues, multiple messaging
patterns, message filtering (subscriptions), seamless access to
multiple transport protocols and more.
This package contains the ZeroMQ shared library.

SYNOPSIS

DESCRIPTION
-----------
The _zmq_bind()_ function shall assign a local address specified by the
'address' argument to the socket referenced by the 'socket' argument.
The _zmq_bind()_ function shall create an endpoint for accepting connections
and bind it to the socket referenced by the 'socket' argument.
The 'address' argument is a string consisting of two parts as follows:
'transport'://'endpoint'. The 'transport' part specifies the underlying
transport protocol to use. The meaning of the 'endpoint' part is specific to
The 'endpoint' argument is a string consisting of two parts as follows:
'transport'`://`'address'. The 'transport' part specifies the underlying

'inproc':: local in-process (inter-thread) communication transport, see linkzmq:zmq_inproc[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]
A single socket may have an arbitrary number of local addresses assigned to it
using _zmq_bind()_, while also being connected to an arbitrary number of peer
addresses using _zmq_connect()_.
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 linkzmq:zmq_socket[3] for a description of the exact
semantics involved when connecting or binding a socket to multiple endpoints.

The following sections present the socket types defined by 0MQ, grouped by the
general _messaging pattern_ built from related socket types.
Request-reply pattern
~~~~~~~~~~~~~~~~~~~~~
The request-reply pattern is used for sending requests from a _client_ to a
_service_, and receiving subsequent replies to each request sent.
Socket type:: 'ZMQ_REQ'
Compatible peer sockets:: 'ZMQ_REP'
A socket of type 'ZMQ_REQ' is used by a _client_ to send requests to and
receive replies from a _service_. This socket type allows only an alternating
sequence of _zmq_send(request)_ and subsequent _zmq_recv(reply)_ calls. Each
request sent is load-balanced among all connected _services_.
Socket type:: 'ZMQ_REP'
Compatible peer sockets:: 'ZMQ_REQ'
A socket of type 'ZMQ_REP' is used by a _service_ to receive requests from and
send replies to a _client_. This socket type allows only an alternating
sequence of _zmq_recv(request)_ and subsequent _zmq_send(reply)_ calls. Each
reply is routed to the _client_ that issued the last received request.
Publish-subscribe pattern

_service_, and receiving subsequent replies to each request sent.
Socket type:: 'ZMQ_REQ'
Compatible peer sockets:: 'ZMQ_REP'
Pipeline pattern
~~~~~~~~~~~~~~~~
The pipeline pattern is used for distributing data to _nodes_ arranged in
a pipeline. Data always flows *down* the pipeline, and each stage of the
pipeline is connected to at least one _node_. When a pipeline stage is
connected to multiple _nodes_ data is processed by all connected _nodes_ in
parallel.

receive replies from a _service_. This socket type allows only an alternating
sequence of _zmq_send(request)_ and subsequent _zmq_recv(reply)_ calls. Each
request sent is load-balanced among all connected _services_.
Socket type:: 'ZMQ_DOWNSTREAM'
Compatible peer sockets:: 'ZMQ_UPSTREAM'
Socket type:: 'ZMQ_REP'
Compatible peer sockets:: 'ZMQ_REQ'
A socket of type 'ZMQ_DOWNSTREAM' is used by a pipeline _node_ to send messages
to downstream pipeline _nodes_. Messages are load-balanced to all connected
downstream _nodes_. The _zmq_recv()_ function is not implemented for this
socket type.
A socket of type 'ZMQ_REP' is used by a _service_ to receive requests from and
send replies to a _client_. This socket type allows only an alternating
sequence of _zmq_recv(request)_ and subsequent _zmq_send(reply)_ calls. Each
reply is routed to the _client_ that issued the last received request.
Socket type:: 'ZMQ_UPSTREAM'
Compatible peer sockets:: 'ZMQ_DOWNSTREAM'
A socket of type 'ZMQ_UPSTREAM' is used by a pipeline _node_ to receive
messages from upstream pipeline _nodes_. Messages are fair-queued from among
all connected upstream _nodes_. The _zmq_send()_ function is not implemented
for this socket type.
Parallelized pipeline pattern
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The parallelized pipeline pattern is used for distributing work between
_components_ of a pipeline. Work travels down the pipeline and at each stage
can be processed by any number of _components_ in parallel.
Socket type:: 'ZMQ_UPSTREAM'
Compatible peer sockets:: 'ZMQ_DOWNSTREAM'
Exclusive pair pattern
~~~~~~~~~~~~~~~~~~~~~~
The exclusive pair pattern is used for communicating exclusively between two
peers.
A socket of type 'ZMQ_UPSTREAM' is used by a _component_ of a pipeline to
receive messages from upstream stages of the pipeline. Messages are fair-queued
from among all connected upstream _components_. The _zmq_send()_ function is
not implemented for this socket type.
Socket type:: 'ZMQ_PAIR'
Compatible peer sockets:: 'ZMQ_PAIR'
Socket type:: 'ZMQ_DOWNSTREAM'
Compatible peer sockets:: 'ZMQ_UPSTREAM'
A socket of type 'ZMQ_PAIR' can only be connected to a single peer at any one
time. No message routing or filtering is performed on messages sent over a
'ZMQ_PAIR' socket.
A socket of type 'ZMQ_DOWNSTREAM' is used by a _component_ of a pipeline to
send messages to downstream stages of the pipeline. Messages are load-balanced
to all connected downstream _components_. The _zmq_recv()_ function is not
implemented for this socket type.
NOTE: 'ZMQ_PAIR' sockets are experimental, and are currently missing several
features such as auto-reconnection. Developers should consider other patterns
in preference to the exclusive pair pattern.
