#include <db.h> int DB->get_slices(DB *db, DB ***slicepp);
         The DB->get_slices() method returns a
         NULL-terminated array of slice databases. Each element in the
         array represents one slice. Note that you should not explicitly
         close these database handles; each slice database is automatically
         closed when the parent database handle is closed.
     
         The DB->get_slices() method may be
         called at any time during the life of the application.
     
         The DB->get_slices() 
            
                  method returns a non-zero error value on failure and 0 on success.
