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.

Programming Linux/Unix Systems

The goal of this chapter is to explain the foundations of programming on Linux/Unix-based systems. This will provide a more complete picture of how a program executes on a Unix/Linux system, how to write more efficient code, and where to look when hard-to-find bugs arise.

To that end, this chapter starts by taking a comprehensive look at the Linux ABI, or more specifically, the System V ABI. In this section, we will review everything from the register and stack layout, to the System V calling conventions and ELF binary object specification.

The next section will briefly cover the Linux filesystem, including the standard layout and permissions. We will then provide a comprehensive review of Unix processes and how to program them, including considerations such as forking new processes and interprocess communication.

Finally, this chapter will conclude...
