In this chapter, weve provided a quick tour of Sockets programming in C. We investigated the Sockets programming paradigm, covering the basic elements of networking such as hosts , interfaces, protocols, and ports. The Sockets API was explored in a sample server and client in C and then in detail looking at the functions of the API. Finally, use of the Sockets API was discussed from a multilanguage perspective, illustrating its applicability to non-C language scenarios.
