Hands-On System Programming with C++

By: Dr. Rian Quinn

Overview of this book

C++ is a general-purpose programming language with a bias toward system programming as it provides ready access to hardware-level resources, efficient compilation, and a versatile approach to higher-level abstractions. This book will help you understand the benefits of system programming with C++17. You will gain a firm understanding of various C, C++, and POSIX standards, as well as their respective system types for both C++ and POSIX. After a brief refresher on C++, Resource Acquisition Is Initialization (RAII), and the new C++ Guideline Support Library (GSL), you will learn to program Linux and Unix systems along with process management. As you progress through the chapters, you will become acquainted with C++'s support for IO. You will then study various memory management methods, including a chapter on allocators and how they benefit system programming. You will also explore how to program file input and output and learn about POSIX sockets. This book will help you get to grips with safely setting up a UDP and TCP server/client. Finally, you will be guided through Unix time interfaces, multithreading, and error handling with C++ exceptions. By the end of this book, you will be comfortable with using C++ to program high-quality systems.

Beginning with the C standard language

The C programming language is one of the oldest languages available. Unlike other higher-level languages, C is similar enough to assembly language programming, while still providing some high-level programming abstractions, that it has become a firm favorite among system, embedded, and kernel-level programmers alike.

Almost every major operating system is rooted in C. In addition, most higher-level languages, including C++, build upon C to provide their higher-level constructs, and therefore still require some of the components of the C standard.

The C standard is a huge standard that is managed by the International Organization for Standardization (ISO). We assume the reader has some basic knowledge of the C standard and how to write C code: http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1256.pdf.

For these reasons, the goal of this...
