The Win32ada binding to the Win32api is a major example of Ada bindings
to C stuff. It comes with the GNAT compiler and is probably available
from lots of other sources as well. (I think Aonix ships with it too,
but I have not looked at that product in a while.)

I personally find it a pain to use because of the large variety of types
for the same things, the constant use of error flags instead of
enumerated types and all the parameters are so C-ish that it doesn't fit
in with The Ada Way of thinking. (Some of this is just because the
Win32api is organically grown rather than engineered.) I'd prefer to see
a "thick" binding that simply hid all of the conversions, error flags,
etc. so that you had something that looked like Ada rather than
C-Written-In-Ada. But I suppose there is a need for the thin binding to
exist.
