If you want really private structures just use C:

struct foo;
typedef struct foo *pFoo;

Now you can use struct foo and pFoo everywhere without knowing anything 
about it. You can't allocate a foo, just a pointer to it, and you can't 
have a local variable of that type. It is 100% hidden and since you 
haven't got any description of its internal fields there is NO WAY you 
can access them.

This is much stronger than C++ "private". It has some drawbacks too, the 
main  one is that you can't do some hack to actually use the protected 
fields :-)
