#[repr(C)]
pub struct IUnknown { /* private fields */ }

Base interface for all COM types.

Implementations

impl IUnknown

pub unsafe fn query_interface( &self, iid: &IID, object: *mut *mut c_void, ) -> HResult

Retrieves pointers to the supported interfaces on an object. Use ComPtr::from instead.

Increments the reference count for an interface on an object. Should never need to call this directly.

pub unsafe fn release(&self) -> u32

Decrements the reference count for an interface on an object. Should never need to call this directly.
