nn_ipc — inter-process transport mechanism
Inter-process transport allows for sending messages between processes within a single box. The implementation uses native IPC mechanism provided by the local operating system and the IPC addresses are thus OS-specific.
On POSIX-compliant systems, UNIX domain sockets are used and IPC addresses are file references. Note that both relative (ipc://test.ipc) and absolute (ipc:///tmp/test.ipc) paths may be used. Also note that access rights on the IPC files must be set in such a way that the appropriate applications can actually use them.
On Windows, named pipes are used for IPC. IPC address is an arbitrary case-insensitive string containing any character except for backslash. Internally, address ipc://test means that named pipe \.\pipe\test will be used.
