How do I handle errors in C++ async libraries?

In C++, error handling in async libraries can be done using futures and exceptions. You can catch exceptions thrown by async tasks.

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

Sure! You can use std::async to run a function asynchronously and then use std::future to retrieve the result. If an exception occurs, it will be thrown when you call get() on the future.

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 specific libraries that help with error handling in async operations?

Yes, libraries like Boost.Asio and C++20's coroutines provide robust mechanisms for error handling in asynchronous operations.
