What are some tools for ensuring thread safety in C++?

There are several tools and techniques for ensuring thread safety in C++. Some popular ones include mutexes, condition variables, and atomic operations.

Can you explain how mutexes work?

Mutexes, or mutual exclusions, are used to protect shared resources from being accessed by multiple threads simultaneously. When a thread locks a mutex, other threads trying to lock it will be blocked until the mutex is unlocked.

What about condition variables?

Condition variables are used in conjunction with mutexes to allow threads to wait for certain conditions to be met before proceeding. They enable threads to sleep and be awakened when a condition changes.

Are there any libraries that help with thread safety?

Yes, libraries like Boost and the C++ Standard Library provide various tools for thread management and synchronization, making it easier to implement thread-safe code.
