Using Ada.Containers.Vector and Limited Private types

I'm trying to sort a collection of Ada.Directories.Directory_Entry (a 
limited private type) by storing pointers to them in a Vector but am 
having problems with accessibility rules.


Is it possible to do this?


Package Ada.Directories only has procedures that have "in out"/out 
parameters for the Directory_Entry type, so I can't figure out how to 
get a reference to each object as I run through the More_Entries/ 
Get_Next_Entry procedures.


Thanks,

Dale
