Hi Max,
- Would including the URL of the MSDN article be useful/a good idea?
No. MSDN is in the habit of changing its URLs all too frequently.
A more general response: I'm not sure that a lot of documentation patches will be accepted. MSDN has to be considered the definitive resource for the Windows API. It's often incorrect, of course, and our regression tests aim to ameliorate the inaccuracy, but we probably have enough work implementing the Windows API without taking on the task of documenting it too. --Juan
