I....do not grok article. I don't use function pointers and jump tables all that much, but I'm pretty sure you could add a function pointer argument to printNTriples and replace the printf() with it and get somewhere if you really needed to get there. Starting to feel like I might be getting to the "Get off my damn lawn, kid!" part of my life.

You could, but the control is still driven by printNTriples. What if you had to break early, before generating all N triples? In this simple case, you could use a return value from the callback to decide whether to continue or not.

In a more general case, you would you would encapsulate the state into a class (for example, the x,y,z,i locals from the original function would become instance memebers.)
