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.

Communication protocols

Having just a communication channel or medium is not enough. Two parties willing to communicate over a shared channel need to understand one another, too! A very simple example is when two people want to talk to each other using the same language, such as English or Japanese. Here, the language can be considered as the protocol used by two parties in order to communicate.

In the context of IPC, processes are no exception; they need a common language so they can communicate. Technically, we use the term protocol to refer to this common language between any two parties. As part of this section, we are going to discuss communication protocols and their various characteristics such as the message length and the message content. Before being able to talk about these characteristics, we need to describe a communication protocol in a deeper sense. Note that our main focus in this chapter is IPC techniques; therefore, we only talk about communication protocols...
