They are referenced by processes as inodes in the file system.
This is not quite correct. On several OS you can set the first byte of the pathname to 0, causing the following name to be looked up in a filesystem independent namespace (without any filesystem access control checks). Even from within a chroot.
The PF_UNIX (also known as PF_LOCAL) socket family is used to communicate between processes on the same machine efficiently. Unix sockets can be either anonymous (created by socketpair) or associated with a file of type socket. Linux also supports an abstract namespace which is independent of the file system.
Valid types are SOCK_STREAM for a stream oriented socket and SOCK_DGRAM for a datagram oriented socket that preserves message boundaries. Unix sockets are always reliable and don't reorder datagrams.
Unix sockets support passing file descriptors or process credentials to other processes using ancillary data. 126.96.36.199 04:58, 4 April 2007
