The docs say that the size is written on failure, but in practice it is also written on success and we rely on that. See #141244 and rust-lang/miri#4332.
We shouldn't use system APIs outside their documented contract, so we should either adjust our implementation or get Microsoft to update the docs to promise this behavior we have been relying on.
