CAggDrawSurface::NonDelegatingQueryInterface (Windows Embedded CE 6.0)
1/6/2010
Retrieves an interface and increments the reference count.
Syntax
HRESULT NonDelegatingQueryInterface(
REFIID riid,
void** ppv
);
Parameters
- riid
Reference identifier.
- ppv
Pointer to the interface.
Return Value
Returns E_POINTER if ppv is invalid.
Returns NOERROR if the query is successful or E_NOINTERFACE if it is not.
Remarks
This member function provides an implementation of the INonDelegatingUnknown::NonDelegatingQueryInterface method.
By default it passes out references to IDirectDrawSurface and then calls the CUnknown::NonDelegatingQueryInterface member function for base class interface references.
Override this class to return interfaces added in the derived class.
