I like how the metadata is "optional" when it probably means "nullable". I doubt calling this without those arguments at all works out that well in practice.

I looked it up - the rules are documented. Which combination of nulls are allowed - if you go the overlapped (async) route you can leave the number of bytes out null and vice versa.

It works fine for IOCTLs that don't need input or output parameters.
