Sgetn/bi::read have two different kinds of things to deal with - items read
from the stream, and items written to the output buffers. Not exactly the
same as memcpy, but related. We actually did consider doing the same to
fread, but this change never made it into one of the shipping betas.

This doc describes use of the checked iterators we have defined:,vs.80).aspx

Are you looking to take your existing iterators and mark them as checked?
