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

EXAMPLES

       Example 1. 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);

       Example 2. 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);
