Using UNIX Domain Stream Sockets

Overview

Overview
UNIX Domain (AF_UNIX) stream sockets provide bidirectional, reliable,
unduplicated flow of data without record boundaries. They offer
significant performance increases when compared with the use of local
internet (AF_INET) sockets, due primarily to lower code execution
overhead. The following table lists the steps involved in creating and
terminating a UNIX Domain BSD Sockets connection using stream
sockets.
