How can I use Boost.Asio for UDP communication in C++?

You can use Boost.Asio to create a UDP socket for communication. First, include the necessary headers and set up your io_context.

Can you provide a simple code example?

Sure! Here's a basic example:

#include <boost/asio.hpp>

using boost::asio::ip::udp;

int main() {
    boost::asio::io_context io_context;
    udp::socket socket(io_context, udp::endpoint(udp::v4(), 12345));
    // Your code for sending/receiving data goes here
}

This sets up a UDP socket on port 12345.

How do I send a message using this socket?

You can use the send_to method. Here's how:

std::string message = "Hello, UDP!";
udp::endpoint receiver_endpoint(boost::asio::ip::address::from_string("127.0.0.1"), 12346);
size_t bytes_sent = socket.send_to(boost::asio::buffer(message), receiver_endpoint);
