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.

C++, RAII, and the GSL Refresher

In this chapter, we will provide an overview of some of the recent advancements of C++ that are leveraged in this book. We will start by providing an overview of the changes made to C++ in the C++17 specification. We will then briefly cover a C++ design pattern called Resource Acquisition Is Initialization (RAII), how it is used by C++, and why it is so important to not only C++ but many other languages that leverage the same design pattern. This chapter will conclude with an introduction to the Guideline Support Library (GSL) and how it can help to increase the reliability and stability of system programming by helping to adhere to the C++ Core Guidelines.

In this chapter, we will cover the following topics:

  • Discussing the advancements made in C++17
  • Outlining RAII
  • Introducing the GSL
