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.

Chapter 2

  1. Yes. Most of the C standard is also part of the POSIX standard. POSIX generally goes above and beyond to provide additional facilities specific to POSIX operating systems. Examples of C and POSIX functions include read() and write().
  2. _start() is the entry point to an application and is usually provided by the C runtime facilities. main() is a function provided by the user and is usually the first function to execute in the user's code, which is eventually called by the C runtime facilities once the application is fully initialized.
  3. Executing global constructors and destructors, and initializing C++ exceptions.
  4. Before.
  1. C++ name mangling embeds the entire signature of a function into the function's symbol. This is not only needed to provide support for function overloading in C++, but also ensures that the linker doesn't accidentally dynamically link...
