Working with UNIX domain sockets

A UNIX Domain Socket or Inter-Process Communication (IPC) socket is a data communications endpoint that allows you to exchange data between processes that run on the same machine. You might ask, why use UNIX domain sockets instead of TCP/IP connections for processes that exchange data on the same machine? First, because UNIX domain sockets are faster than TCP/IP connections and second, because UNIX domain sockets require fewer resources than TCP/IP connections. So, you can use UNIX domain sockets when both the clients and the server are on the same machine.

A UNIX domain socket server

This section illustrates how to develop a UNIX domain socket server. Although we do not have to deal with TCP ports and network connections, the code presented is very similar to the code of the TCP server as found in tcpS.go and concTCP.go. The presented server implements the echo service.

The source code of socketServer.go is as follows:

package main...
