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.

Multithreading versus multi-processing

After discussing multithreading and multi-processing in Chapter 14, Synchronization, together with concepts we have covered throughout the recent chapters, we are in a good position to compare them and give a high-level description of situations in which each of the approaches should be employed. Suppose that we are going to design a piece of software that aims to process a number of input requests concurrently. We discuss this in the context of three different situations. Let's start with the first one.

Multithreading

The first situation is when you can write a piece of software that has only one process, and all the requests go into the same process. All the logic should be written as part of the same process, and as a result, you get a fat process that does everything in your system. Since this is single-process software, if you want to handle many requests concurrently, you need to do it in a multithreaded way by creating threads...
