Depends on what "i.e." is supposed to mean.

I think that's more clear:
The number of bytes returned is stored in *len. A backend must set
this to zero when a status other than SANE_STATUS_GOOD is returned.
Is this clear enough or should we add another sentence concerning
SANE_STATUS_EOF (in addition to "SANE_STATUS_EOF: No more data is
available for the current frame.")?
