 NAME
   dce_db_iter_next_by_uuid - During iteration, returns the next key
                              from a backing store indexed by UUID

 SYNOPSIS

   #include <dce/dce.h>
   #include <dce/dbif.h>

   void dce_db_iter_next_by_uuid( dce_db_handle_t handle,
                                  uuid_t **key,
                                  error_status_t *status );

 PARAMETERS

   Input

   handle    A handle, returned from dce_db_open(), that identifies
             the backing store being used.

   Output

   key       The UUID that is the key to the item in the backing store.

   status    A pointer to the completion status.  On successful
             completion, the routine returns error_status_ok.
             Otherwise, it returns an error.

 DESCRIPTION

   The dce_db_iter_next_by_uuid() routine retrieves the next key
   from the backing store that is identified by the handle parameter.
   An iterator established by the dce_db_iter_start() routine maintains
   the identity of the current key.  Use the dce_db_fetch_by_uuid()
   routine to retrieve the actual data.

   This iteration routine is the same as dce_db_iter_next(), except
   that it only works with backing stores indexed by UUID, and returns
   an error if the backing store index is the wrong type.

   The iteration routine returns a pointer to a private space
   associated with the handle.  Each call to the iteration routine
   reuses the space, instead of using allocated space.

 ERRORS

   error_status_ok
             The call was successful.
