Package Hierarchy and Private functions

["RasikaSrinivasan@gmail.com" <RasikaSrinivasan@gmail.com>]

Friends

Supposing we have 2 packages like :

package P is
  type Pvt_T is private ;
private
  type Pvt_T is ... ;
  procedure Pvt_Proc(p : in out Pvt_T) ;
end P ;

---------------------

package P.C is
....
end P.C ;

------------------

Is there a way for P.C to access Pvt_Proc (instead of making it
public). I guess this may be analogous to protected in C++?

Does P.C has a special relationship to P?

any pointers/advice appreciated. thanks, srini
