Hands-On System Programming with C++
Build performant and concurrent Unix and Linux systems with C++17

About This Book
A hands-on guide to making system programming with C++ easy
Key Features
- Write system-level code leveraging C++17
- Learn the internals of the Linux Application Binary Interface (ABI) and apply it to system programming
- Explore C++ concurrency to take advantage of server-level constructs
Book Description
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.
What you will learn
- Understand the benefits of using C++ for system programming
- Program Linux/Unix systems using C++
- Discover the advantages of Resource Acquisition Is Initialization (RAII)
- Program both console and file input and output
- Uncover the POSIX socket APIs and understand how to program them
- Explore advanced system programming topics, such as C++ allocators
- Use POSIX and C++ threads to program concurrent systems
- Grasp how C++ can be used to create performant system applications
Who this book is for
If you are a fresh developer with intermediate knowledge of C++ but little or no knowledge of Unix and Linux system programming, this book will help you learn system programming with C++ in a practical way.
