But we are talking here of knowing an implementation detail, namely, how
many fields in the (otherwise unknown) structure. I assume firewind's
question was, assuming you do know the number of fields, but you have no
other clue of what thsoe fields mean, how would you use that data to your
advantage. His words "using the structure" I read as "using the number of
fields for modifying the object."
