How do I use Boost.Asio timers in C++?

How do I use Boost.Asio timers in C++?

You can use Boost.Asio's steady_timer to create timers. First, include the necessary headers and set up an io_context.

Can you show me a simple example of setting a timer?

Sure! Here's a basic example:

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

void print(const boost::system::error_code& /*e*/) {
    std::cout << "Timer expired!" << std::endl;
}

int main() {
    boost::asio::io_context io;
    boost::asio::steady_timer timer(io, std::chrono::seconds(5));
    timer.async_wait(&print);
    io.run();
    return 0;
}

What happens if I want to cancel the timer?

You can call timer.cancel() to cancel the timer before it expires. Make sure to handle the error code in your callback.

Are there any other types of timers in Boost.Asio?

Yes, Boost.Asio also provides high_resolution_timer and system_timer, which can be used for different timing needs.
