Notes

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. 220.225.70.2 04:58, 4 April 2007

Why do the external links point to copies of the Linux documentation on an ad-covered page, rather than the authoritative source? --David Chisnall (talk) 18:35, 19 November 2007 (UTC)[reply]
