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.

Process Execution

We are now ready to talk about the software systems consisting of more than one process in their overall architecture. These systems are usually called multi-process or multiple-process systems. This chapter, together with the next chapter, is trying to cover the concepts of multi-processing and conduct a pros-and-cons analysis in order to compare it with multithreading, which we covered in Chapter 15, Thread Execution, and Chapter 16, Thread Synchronization.

In this chapter, our focus is the available APIs and techniques to start a new process and how process execution actually happens, and in the next chapter, we'll go through concurrent environments consisting of more than one process. We are going to explain how various states can be shared among a number of processes and what common ways of accessing shared state in a multi-processing environment are.

A proportion of this chapter is based on comparing multi-processing and multithreading...
