There are no 0-sized objects.  Therefore the implementation may do what
it wants in this case.  I would suggest returning 0, which is not only
a technically correct answer (any nonnegative integer from 0 through
the number of records requested would be correct), but is also most
useful in detecting this misusage during software development.
