What are some examples of thread-safe functions?

What are some examples of thread-safe functions?

Thread-safe functions are designed to be safely called by multiple threads simultaneously. Examples include functions that use locks, atomic operations, or thread-local storage.

Can you explain how locks work in thread-safe functions?

Locks are mechanisms that prevent multiple threads from accessing a resource simultaneously. When a thread acquires a lock, other threads must wait until the lock is released.

What are atomic operations?

Atomic operations are operations that complete in a single step relative to other threads. They are indivisible and ensure that a variable is updated without interruption.

Are there any libraries that help with thread safety?

Yes, many programming languages have libraries for thread safety, such as the threading module in Python or java.util.concurrent in Java.
