What are some examples of thread-safe functions?

Can you give me some examples of thread-safe functions?

Sure! Thread-safe functions are designed to be safely called by multiple threads at the same time. Examples include functions that use locks, atomic operations, or thread-local storage.

What are atomic operations?

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

Can you provide an example of an atomic operation?

An example of an atomic operation is incrementing a counter using atomic increment functions provided by libraries like C++'s std::atomic.

How do locks help in making functions thread-safe?

Locks prevent multiple threads from accessing a resource simultaneously, ensuring that only one thread can execute a critical section of code at a time.
