Re: Object-oriented programming in standard ANSI C

Your approach is similar to the results of my experiments with OO in
C. You can increase encapsulation when you only forward declare your
structs (e.g. struct Shape) in the header files.

Unfortunately, your approach precludes automatic function inlining.

Also some functions (e.g. actualShape_draw) can be removed form the header
and made 'private', i.e. static, in the respecive *.c file.

This would preclude any explicit call to function actualShape_draw.
An optimizing C++ compiler will elide the virtual {messenger} function
and call the actual function directly
if it can determine the actual type at compile time.
