I think that Todd and Matthew are using the term "residual" in opposite
ways.  Todd seems to mean "the value returned by the write() call, which
is the number of bytes successfully written", and Matthew seems to mean
"the number of bytes left over, *not* successfully written". 

Fix that terminology difference, and I think that they really agree with
each other.
