How can I handle timeouts in Boost.Asio?

You can handle timeouts in Boost.Asio by using the deadline_timer class to set a timeout for your operations.

Can you show me a code example of using deadline_timer?

Sure! Here's a simple example:

#include <boost/asio.hpp>
#include <iostream>

void handle_timeout(const boost::system::error_code& error) {
    if (!error) {
        std::cout << "Operation timed out!" << std::endl;
    }
}

int main() {
    boost::asio::io_context io;
    boost::asio::deadline_timer timer(io, boost::posix_time::seconds(5));
    timer.async_wait(&handle_timeout);
    io.run();
    return 0;
}

What happens if the operation completes before the timeout?

If the operation completes before the timeout, the handle_timeout function won't be called, and the timer will be canceled.

Are there any best practices for using timeouts in Boost.Asio?

Yes, it's best to always check for errors, use appropriate timeout durations, and ensure timers are canceled when no longer needed.
