Overview of this book

With the release of the Raspberry Pi 2, a new series of the popular compact computer is available for you to build cheap, exciting projects and learn about programming. In this book, we explore Raspberry Pi 2’s hardware through a number of projects in a variety of programming languages. We will start by exploring the various hardware components in detail, which will provide a base for the programming projects and guide you through setting up the tools for Assembler, C/C++, and Python. We will then learn how to write multi-threaded applications and Raspberry Pi 2’s multi-core processor. Moving on, you’ll get hands on by expanding the storage options of the Raspberry Pi beyond the SD card and interacting with the graphics hardware. Furthermore, you will be introduced to the basics of sound programming while expanding upon your knowledge of Python to build a web server. Finally, you will learn to interact with the third-party microcontrollers. From writing your first Assembly Language application to programming graphics, this title guides you through the essentials.

Chapter 4. Multithreaded Applications with C/C++

In this chapter we will explore the Raspberry Pi 2 further via the C/C++ languages and a technology known as threads.

This chapter builds upon the previous material and will help you to understand how applications can run tasks concurrently. In addition to this, you will see how these concurrent operations can access a shared memory space and manipulate its value without overwriting each other's computations.

Topics also covered include the following:

  • A look at pthreads

  • Writing threaded applications in C

  • Adapting a C-based threaded application for C++

  • Understanding mutexes

To start with we will look at what threads are before writing several applications in both C and C++.
