[−][src]Struct com_rs::IUnknown
Base interface for all COM types.
None of the methods on this struct should be called directly,
use ComPtr instead.
Methods
impl IUnknown[src]
pub unsafe fn query_interface(
&self,
iid: &IID,
object: *mut *mut c_void
) -> HResult[src]
&self,
iid: &IID,
object: *mut *mut c_void
) -> HResult
Retrieves pointers to the supported interfaces on an object.
Use ComPtr::from instead.
pub unsafe fn add_ref(&self) -> u32[src]
Increments the reference count for an interface on an object. Should never need to call this directly.
pub unsafe fn release(&self) -> u32[src]
Decrements the reference count for an interface on an object. Should never need to call this directly.
