for (; !pblockrefit->done(); pblockrefit->step())

dbblockreference has method "oddbobjectid blocktablerecord()".

oddbblockreference can not have attributes so you don't enter in the "for".

what getstartpoint() and getendpoint of the block means? oddbblockreference has position() and you can get geometry extents(getgeomextents(odgeextents3d& extents)).
best regards,
