#include <db_cxx.h> int DbEnv::get_slices(DbEnv ***slicepp);
         The DbEnv::get_slices() method returns a
         NULL-terminated array of slice environments. Each element in the
         array represents one slice.
     
         The DbEnv::get_slices() method may only
         be called after the environment has been opened.
     
         The DbEnv::get_slices() 
            
            
                method either returns a non-zero error value or throws an
                exception that encapsulates a non-zero error value on
                failure, and returns 0 on success.
