pathname: a UNIX domain socket can be bound to a null-terminated file system pathname using bind (2). When the address of the socket is returned by getsockname (2), getpeername (2), and accept (2), its length is offsetof (struct sockaddr_un, sun_path) + strlen (sun_path) + 1, and sun_path contains the null-terminated pathname.

A program may test for the macro BOOST_ASIO_HAS_LOCAL_SOCKETS to determine whether … While network (AF_INET) and UNIX domain (AF_UNIX) are both created using the socket() function call, both use connect() to connect to, both use read() and write() to process data, they are handled by different kernel subsystems.

A unix domain socket (sometimes shortened to unix socket) on the other hand operates on a single machine. Listening sockets live in the filesystem hierarchy and access to them can be controlled by filesystem permissions. Furthermore a process accepting a connection on a Unix socket can determine the user ID of the process that connects.
