My main intention was always to learn new things about C++ and hence I always tried to choose the path of maximum resistance and hence tried to work on lower level concepts with my limited abilities. So there is select, poll, dev/poll, event ports, kqueue, epoll, io_uring and i/o completeion ports, on various operating systems that you can use to build something to send/receive bits in/out of the wire. So this was more of a learning and building exercise rather than going with the best option available out there.
Agreed documentation is really poor, but I have really enjoyed building the framework and have never really been focusing on the docs, point taken, thanks.
