ZMQ_INPROC(7)			  0MQ Manual			 ZMQ_INPROC(7)

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 endpoint is a string consisting of	a transport:// followed	by an
       address.	The transport specifies	the underlying protocol	to use.	The
       address specifies the transport-specific	address	to connect to.

       For the in-process transport, the transport is inproc, and the meaning
       of the address part 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. Before version 4.0 he	name
       must have been previously created by assigning it to at least one
       socket within the same 0MQ context as the socket	being connected. Since
       version 4.0 the order of	zmq_bind() and zmq_connect() does not matter
       just like for the tcp transport type.

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);
