NAME

6       zmq_ipc - 0MQ local inter-process communication transport
7

SYNOPSIS

9       The inter-process transport passes messages between local processes
10       using a system-dependent IPC mechanism.
11
12           Note
13           The inter-process transport is currently only implemented on
14           operating systems that provide UNIX domain sockets.
15

ADDRESSING

17       A 0MQ address string consists of two parts as follows:
18       transport://endpoint. The transport part specifies the underlying
19       transport protocol to use, and for the inter-process transport shall be
20       set to ipc. The meaning of the endpoint part for the inter-process
21       transport is defined below.
22
23   Assigning a local address to a socket
24       When assigning a local address to a socket using zmq_bind() with the
25       ipc transport, the endpoint shall be interpreted as an arbitrary string
26       identifying the pathname to create. The pathname must be unique within
27       the operating system namespace used by the ipc implementation, and must
28       fulfill any restrictions placed by the operating system on the format
29       and length of a pathname.
30
31   Connecting a socket
32       When connecting a socket to a peer address using zmq_connect() with the
33       ipc transport, the endpoint shall be interpreted as an arbitrary string
34       identifying the pathname to connect to. The pathname must have been
35       previously created within the operating system namespace by assigning
36       it to a socket with zmq_bind().

EXAMPLES

42       Assigning a local address to a socket.
43
44           /* Assign the pathname "/tmp/feeds/0" */
45           rc = zmq_bind(socket, "ipc:///tmp/feeds/0");
46           assert (rc == 0);
47
48       Connecting a socket.
49
50           /* Connect to the pathname "/tmp/feeds/0" */
51           rc = zmq_connect(socket, "ipc:///tmp/feeds/0");
52           assert (rc == 0);
