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.

Socket programming review

In this section, we are going to discuss what sockets are, what their various types are, and generally what it means if we say that we are doing socket programming. This is going to be a short review, but it is essential to build this basis so that we can continue into deeper discussion in subsequent sections.

If you remember from the previous chapters, we have two categories of IPC techniques to be used by two or more processes to communicate and share data. The first category contains pull-based techniques that require an accessible medium (such as a shared memory or a regular file) to store data to and retrieve data from. The second category contains push-based techniques. These techniques require a channel to be established and the channel should be accessible by all processes. The main difference between these categories is regarding the way that data is retrieved from a medium in pull-based techniques, or a channel in push-based techniques...
