CComCachedTearOffObject::QueryInterface

HRESULT QueryInterface( REFIID iid , void** ppvObject );

Return Value

A standard HRESULT value.

Parameters

iid

[in] The GUID of the interface being requested.

ppvObject

[out] A pointer to the interface pointer identified by iid, or NULL if the interface is not found.

Remarks

Retrieves a pointer to the requested interface. If the requested interface is IUnknown, returns a pointer to the CComCachedTearOffObject's own IUnknown and increments the reference count. Otherwise, queries for the interface on your tear-off class using the InternalQueryInterface method inherited from CComObjectRootEx.
