Overview of this book

Functional programming allows developers to divide programs into smaller, reusable components that ease the creation, testing, and maintenance of software as a whole. Combined with the power of C++, you can develop robust and scalable applications that fulfill modern day software requirements. This book will help you discover all the C++ 17 features that can be applied to build software in a functional way. The book is divided into three modules—the first introduces the fundamentals of functional programming and how it is supported by modern C++. The second module explains how to efficiently implement C++ features such as pure functions and immutable states to build robust applications. The last module describes how to achieve concurrency and apply design patterns to enhance your application’s performance. Here, you will also learn to optimize code using metaprogramming in a functional way. By the end of the book, you will be familiar with the functional approach of programming and will be able to use these techniques on a daily basis.

Preface

Understanding the thread processing in a Windows operating system


Let's move to a specific operating system that is widely used by many user computers, that is Windows. Our code must need to be run on some commercial platform from a leading OS vendor, such as Microsoft. So, we will now run the thread in Windows OS. In this OS, the thread is a kernel resource, which means it is an object that is created and owned by the OS kernel and lives in the kernel. The kernel itself is a core program that has complete control over everything in the system. In this section, we will develop a thread in Windows OS so our program can work well in this OS.

Working with handle

In the Windows operating system, handle is an abstract reference value to a resource. In this discussion, we will use the abstract reference to hold the thread. Let's suppose we have a threadProc() function that will be called inside a thread which is held in the hnd variable. The code will be as follows:

    /* threadhandle.cpp */
