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,
