How do I implement thread-safe functions?

What are thread-safe functions and why are they important?

Thread-safe functions are designed to function correctly when accessed by multiple threads simultaneously. They prevent data corruption and ensure consistent results.

How can I make my existing functions thread-safe?

You can make functions thread-safe by using synchronization mechanisms like mutexes, semaphores, or by avoiding shared state.

Can you give me an example of a thread-safe function?

Sure! Here's a simple example using a mutex in C++:

#include <mutex>
std::mutex mtx;

void threadSafeIncrement(int &counter) {
    mtx.lock();
    ++counter;
    mtx.unlock();
}

What are the performance implications of using thread-safe functions?

Using thread-safe functions can introduce overhead due to locking mechanisms, which may impact performance. It's essential to balance safety and efficiency.
