30. Threads: Thread Synchronization

Chapter 30. Threads: Thread Synchronization

In this chapter, we describe two tools that threads can use to synchronize their actions: mutexes and condition variables. Mutexes allow threads to synchronize their use of a shared resource, so that, for example, one thread doesn’t try to access a shared variable at the same time as another thread is modifying it. Condition variables perform a complementary task: they allow threads to inform each other that a shared variable (or other shared resource) has changed state.
