Keterangan

Implementasi runtime dari fungsi-fungsi ini IUnknown semuanya aman untuk utas. Masing-masing dioptimalkan dan secara ketat mengikuti aturan COM untuk IUnknown. Implementasinya QueryInterface juga menghormati ICustomQueryInterface antarmuka. Antarmuka ICustomQueryInterface tidak akan pernah memiliki kesempatan untuk mengambil alih antarmuka yang disediakan runtime. Misalnya, secara default runtime menyediakan IUnknown antarmuka dan, secara opsional, antarmuka Pelacak IReferenceTrackerTarget Referensi.
