The root interface. A *mut IUnknown is a native IUnknown*.

Implementations

impl IUnknown

pub unsafe fn query_interface_raw( &self, riid: &Guid, ppv: *mut *mut c_void, ) -> RawHResult

Safety

Raw COM call; ppv must be valid for writes.

pub unsafe fn add_ref(&self) -> u32

Safety

Raw reference-count manipulation.

pub unsafe fn release(&self) -> u32

Safety

Raw reference-count manipulation; self may be dangling afterwards.
