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.

Shared states

As with threads, we can have some shared states between processes. The only difference is that the threads are able to access the same memory space owned by their owner process, but processes cannot have that luxury. Therefore, other mechanisms should be employed to share a state among a number of processes.

In this section, we are going to discuss these techniques and as part of this chapter, we focus on some of them that function as storage. In the first section, we will be discussing different techniques and trying to group them based on their nature.

Sharing techniques

If you look at the ways you can share a state (a variable or an array) between two processes, it turns out that it can be done in a limited number of ways. Theoretically, there are two main categories of sharing a state between a number of processes, but in a real computer system, each of these categories has some subcategories.

You either have to put a state in a "place"...
