I guess you could do that, although structurally XY instruments are
intended to be implemented in the driver code, and chartread then deals
with them generically. For something like you are proposing (or the io), the
more natural way of adding that support would be as a psudo XY instrument
which is then a shim over the i1Pro driver.

Hmm. At least C is 5 x easier than C++ to learn, but porting to a new compile
environment is not fun, and might be an extreme test for a novice in the
language.
I haven't tried to compile Argyll in anything beyond VC++10, and I'm guessing
that VS 2013 Express won't install on my XP development machine without
some cunning & effort. So I could suggest that you could probably more easily
compile using MingW, but I know that is not going to be very attractive
for someone used to using Visual Studio.

Binary negate or complement.

The above message seems to hint at some problem with C++ changes leaking into
your
compilation. Are you sure you are compiling the Argyll source as C and not C++ ?
