Question

What is the simplest way in C++ (an actual code example would be great) to establish/open a UDP unicast connection if I know the IP address and port?

The resolver/query/endpoint/iterator stuff seems a bit like overkill and at my level of understanding, so far a bit confusing.

First of all I’m new to Boost, but I have done some work with the Boost.Asio library.

Answer 1

There is an example here that uses resolvers etc.

If you wish to use an ip address that you already have, you can do something like this:

boost::asio::ip::address ip_add = boost::asio::ip::address::from_string("192.168.1.1");
tcp::endpoint remoteEndpoint( ip_add , portno );

This is for TCP, but I expect you can do something similar for UDP.
