How do I handle errors in C++11 asynchronous programming?

What are the best practices for handling errors in C++11 async functions?

In C++11, you can use futures and exceptions to handle errors. Always check the future's status before accessing its value.

Can you give me an example of using futures for error handling?

Sure! You can wrap your async call in a try-catch block and return a future that holds either the result or an exception.

What happens if I don't handle exceptions in async tasks?

If you don't handle exceptions, they may lead to program termination or undefined behavior. It's crucial to manage them properly.

Are there any libraries that simplify async error handling in C++?

Yes, libraries like Boost.Asio and C++17's std::optional can help manage async tasks and their errors more effectively.
