And that’s why the Paho embedded client libraries now exist - for all those other embedded operating systems that are now popular!
That’s why I wrote these libraries with Linux (and some other forms of Unix) and Windows in mind, rather than being any more portable. It seemed to me at the time that Linux was likely to take over the world for embedded systems, with Windows CE maybe getting a look in. That’s why the client libraries are C too. I started writing RSMB in C++, but the template support in gcc at the time did not work well, so I switched to standard ANSI C. RSMB is single-threaded, which I mainly retained in the design of these client libraries, for better or worse. As it turned out, I probably didn’t save as much time as I expected, because in some ways writing a client library for MQTT is more complex than writing a server. I thought I would reuse as much of the internal code of RSMB as I could, to save myself some time. The Paho C client libraries started life back in 2007, when I first started writing a small MQTT server, RSMB (Really Small Message Broker).
