zmq_inproc: 0MQ local in-process (inter-thread) communication transport

NAME

zmq_inproc - 0MQ local in-process (inter-thread) communication transport

SYNOPSIS

The in-process transport passes messages via memory directly between threads sharing a single 0MQ context. Note No I/O threads are involved in passing messages using the inproc transport. Therefore, if you are using a 0MQ context for in-process messaging only you can initialise the context with zero I/O threads. See zmq_init(3) for details.

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 in-process transport shall be set to inproc. The meaning of the endpoint part for the in-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 inproc transport, the endpoint shall be interpreted as an arbitrary string identifying the name to create. The name must be unique within the 0MQ context associated with the socket and may be up to 256 characters in length. No other restrictions are placed on the format of the name. Connecting a socket When connecting a socket to a peer address using zmq_connect() with the inproc transport, the endpoint shall be interpreted as an arbitrary string identifying the name to connect to. The name must have been previously created by assigning it to at least one socket within the same 0MQ context as the socket being connected.
WIRE FORMAT
Not applicable.
EXAMPLES
Assigning a local address to a socket. /* Assign the in-process name "#1" */ rc = zmq_bind(socket, "inproc://#1"); assert (rc == 0); /* Assign the in-process name "my-endpoint" */ rc = zmq_bind(socket, "inproc://my-endpoint"); assert (rc == 0); Connecting a socket. /* Connect to the in-process name "#1" */ rc = zmq_connect(socket, "inproc://#1"); assert (rc == 0); /* Connect to the in-process name "my-endpoint" */ rc = zmq_connect(socket, "inproc://my-endpoint"); assert (rc == 0);
