What are some tools for ensuring thread safety in programming?

There are several tools and techniques for ensuring thread safety, such as mutexes, semaphores, and atomic operations. Would you like to know more about any specific tool?

Can you explain how mutexes work?

Mutexes, or mutual exclusions, are used to prevent multiple threads from accessing a shared resource simultaneously. When a thread locks a mutex, other threads must wait until it is unlocked.

What are the advantages of using semaphores over mutexes?

Semaphores allow a certain number of threads to access a resource concurrently, which can be more flexible than mutexes that only allow one thread at a time. This can improve performance in certain scenarios.

Are there any libraries that can help with thread safety?

Yes, many programming languages have libraries for thread safety. For example, C++ has the <thread> library, and Java has the java.util.concurrent package.
