This is a presentation “How to Call C libraries from C++” I first gave at Cppcon in 2014. The slides alone probably aren’t very readable, but the conference plans to make video available. I presented a much earlier version of this material at MacHack in 2002. There is a paper “The Nitrogen Manifesto” available for that work at nitric.sourceforge.net. The source code here is divided into three parts: main.cpp an example; a simple communication program Po7 a library that brings (part of) POSIX to C++ PlusPlus a small library for making libraries like Po7 I’m releasing all of these into the public domain. I don’t expect to do much public support or extension of this code. Share and enjoy! —-Lisa Lippincott September 10, 2014
