I was thinking that these structures are for userspace only.  I don't have a
strong opinion on this, and was trying to match whatever was most suitable for a
Windows API, so I matched what NDI did.

If the structure does end up shared between userspace and the kernel, I would
use UINT32 or UITN64 to save myself head-aches as you mentioned.
