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.

The Linux ABI

In this section, we will discuss the Linux ABI (which is actually called the System V ABI), as well as the ELF standard and its use in Linux/Unix.

We will also dive into some of the details associated with ELF files, how to read and interpret them, and some of the implications of specific components within an ELF file.

The System V ABI

Unix System V was one of the first versions of Unix available, and largely defined Unix for years. Under the hood, System V leveraged the System V ABI. As Linux and BSD (Unix-like operating systems) became more widely used, the popularity of System V declined. However, the System V ABI remained popular, as operating systems such as Linux adopted this specification for Intel-based...
