C++ Thread Library: Async Best Practices

What are some best practices for using the C++ thread library?

When using the C++ thread library, it's important to manage thread lifetimes, avoid data races, and use mutexes for synchronization.

Can you explain how to avoid data races?

To avoid data races, ensure that shared data is accessed by only one thread at a time. Use mutexes or other synchronization mechanisms.

What is the difference between std::thread and std::async?

std::thread creates a new thread for execution, while std::async may run tasks asynchronously and can return a future for the result.

Are there any performance considerations I should be aware of?

Yes, creating too many threads can lead to overhead. It's often better to use a thread pool or limit the number of concurrent threads.
