It's so old that I've forgotten the details but it's just one of
the options for internal IPC. I believe it is basically a named
pipe in the filesystem space. It's a convenient way to configure
your IPC for local or 'global' access without having to change
the code.
All of the local IPC mechanisms, pipes, queues, etal, probably boil
down to a shared memory implementation in the kernel, they just have
different access semantics. The named pipes are convenient because
you can connect them up by finding the end-points in the file system,
without having to have a common parent process.
Caveat -- all information from memory and one online man page --

Hi ,
In sockets we say that the domain types are like AF_INET and AF_UNIX,
the first is used for the Internet and the second one for the UNIX IPC,does
it mean that to AF_UNIX domain is used to communicate with the process
running in the same machine if yes during what secnarios do we use them....
bcoz in unix we have pipes and fifos 2 communicate between the process
which have the same
ancestors...in same machine then message queues ,shared memory etc
between different unrelated
process in the same machine and sockets between different machine...
Thanks and Regards,
