How can I handle errors in Boost.Asio with C++?

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 error occurred.

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

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

What should I do if I encounter a timeout error?

For timeout errors, you can implement a timer using boost::asio::steady_timer. If the timer expires before the operation completes, you can cancel the operation and handle the timeout.

Is there a way to log errors for debugging?

Yes, you can log errors by using a logging library or simply outputting the error message to the console. Use error_code.message() to get a human-readable error description.
