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().

WIRE FORMAT

       Not applicable.

EXAMPLES

       Assigning a local address to a socket.

	   /* Assign the pathname "/tmp/feeds/0" */
	   rc = zmq_bind(socket, "ipc:///tmp/feeds/0");
	   assert (rc == 0);

       Connecting a socket.

	   /* Connect to the pathname "/tmp/feeds/0" */
	   rc = zmq_connect(socket, "ipc:///tmp/feeds/0");
	   assert (rc == 0);
