NAME

----
|
|
zmq_ipc - 0MQ local inter-process communication transport
|
|
|
|
|
|
SYNOPSIS
|
|
--------
|
|
The inter-process transport passes messages between local processes using a
|
|
system-dependent IPC mechanism.
|
|
|
|
NOTE: The inter-process transport is currently only implemented on operating
|
|
systems that provide UNIX domain sockets.
|
|
|
|
|
|
ADDRESSING
|
|
----------
|
|
A 0MQ address string consists of two parts as follows:
|
|
'transport'`://`'endpoint'. The 'transport' part specifies the underlying
|
|
transport protocol to use, and for the inter-process transport shall be set to
|
|
`ipc`. The meaning of the 'endpoint' part for the inter-process transport is
|
|
defined below.
|
|
|
|
|
|
Assigning a local address to a socket
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
When assigning a local address to a 'socket' using _zmq_bind()_ with the 'ipc'
|
|
transport, the 'endpoint' shall be interpreted as an arbitrary string
|
|
identifying the 'pathname' to create. The 'pathname' must be unique within the
|
|
operating system namespace used by the 'ipc' implementation, and must fulfill
|
|
any restrictions placed by the operating system on the format and length of a
|
|
'pathname'.
|
|
|
|
Connecting a socket
|
|
~~~~~~~~~~~~~~~~~~~
|
|
When connecting a 'socket' to a peer address using _zmq_connect()_ with the
|
|
'ipc' transport, the 'endpoint' shall be interpreted as an arbitrary string
|
|
identifying the 'pathname' to connect to. The 'pathname' must have been
|
|
previously created within the operating system namespace by assigning it to a
|
|
'socket' with _zmq_bind()_.
