That does make more sense than the object partitioning I assumed. And you are right in that it does appear to have about equal trade off as global functions. Why do you have such a fear of global functions?

Actually you make them into a library, separate source file with local variables and functions. C encapsulates code as well as C++ does.

But we are drifting off topic.
