Overview of this book

There’s a lot more to C than knowing the language syntax. The industry looks for developers with a rigorous, scientific understanding of the principles and practices. Extreme C will teach you to use C’s advanced low-level power to write effective, efficient systems. This intensive, practical guide will help you become an expert C programmer. Building on your existing C knowledge, you will master preprocessor directives, macros, conditional compilation, pointers, and much more. You will gain new insight into algorithm design, functions, and structures. You will discover how C helps you squeeze maximum performance out of critical, resource-constrained applications. C still plays a critical role in 21st-century programming, remaining the core language for precision engineering, aviations, space research, and more. This book shows how C works with Unix, how to implement OO principles in C, and fully covers multi-processing. In Extreme C, Amini encourages you to think, question, apply, and experiment for yourself. The book is essential for anybody who wants to take their C to the next level.

Unix domain sockets

From the previous chapter, we know that if we are going to establish a connection between two processes on the same machine, UDS are one of the best options. In this chapter, we expanded our discussion and talked a bit more about push-based IPC techniques, as well as stream and datagram channels. Now it's time to gather our knowledge from previous and current chapters and see UDS in action.

In this section, we have four subsections dedicated to processes being on the listener side or the connector side and operating on a stream or a datagram channel. All of these processes are using UDS. We go through the steps they should take to establish the channel, based on the sequences we discussed in the previous chapter. As the first process, we start with the listener process operating on a stream channel. This would be the stream server.

If you remember from the previous chapter, we had a number of sequences for listener and connector sides...
