Yes, that shouldn't happen. OTOH, only looking at the callee side,
one may wonder that the possible error would be dpn[] overflows the
given array size (=count). Though, looking at both caller and callee,
one realizes that it shouldn't happen, too.
(But then again wonders why passing count argument at all :)
