What you've show is data abstraction, _not_ object-oriented programming.
To do OOP you'd need a table of function pointers or a similar
structure to implement virtual functions/messages and probably some
macros to make it all look nice.  OOP implies a "foo isa
bar" relationship.

Can it be done in C?  Sure.  But why anyone would use C for this instead
of C++ is beyond me.
