There was a problem hiding this comment.
Noting to self that this needs to use CountParamIndex so that this special piece of code in windows-rs translates the function argument to &mut [u16] (unfortunately loosing the PWSTR type) to pass the "capacity" of the output string into cch* without users having to do so manually:
Since there are a few more functions with CountFieldName attributes, maybe those should be renamed or windows-rs needs to lookup by name as well?
(Bonus: PWSTR can't be used as function argument because it defines the length based on strlen() that searches for a NUL-terminator, which isn't defined for an arbitrary "output only" buffer. The transparent PWSTR pointer wrapper "newtype" doesn't behave like an "owned" Rust Vec which carries a length and capacity field)
