How do I handle errors in Boost.Asio?

In Boost.Asio, you can handle errors by checking the error code returned by asynchronous operations. Use the boost::system::error_code to determine if an operation succeeded or failed.

Can you give me an example of error handling in a TCP connection?

Sure! When you initiate an asynchronous connect operation, you can pass a handler that takes an error code as a parameter. Check if the error code is not boost::asio::error::success to handle the error accordingly.

What should I do if I encounter a timeout error?

For timeout errors, you can set a deadline timer that cancels the operation if it exceeds a specified duration. This way, you can handle the timeout gracefully.

Is there a way to log errors for debugging?

Yes, you can log errors by using a logging library or simply printing the error message to the console. Make sure to include the error code and any relevant context.
