Using Mutexes, Semaphores, and Condition Variables

This chapter will focus on the most common mechanisms you can use to synchronize access to a shared resource. The synchronization mechanisms we will look at prevent a critical section (the program segment responsible for a resource) from being executed concurrently from two or more processes or threads. In this chapter, you'll learn how to use both POSIX and C++ standard library synchronization building blocks such as mutexes, std::condition_variable, std::promise, and std::future.

This chapter will cover the following recipes: 

• Using POSIX mutexes
• Using POSIX semaphores
• POSIX semaphores advanced usage
• Synchronization building blocks
• Learning inter-thread communication with simple events
• Learning inter-thread communication with condition variables
