Returns the object from which the view was created.
HRESULT GetSpecification (
REFIID riid,
IUnknown ** ppObject);
Parameters
riid
[in]
The IID of the interface to be returned. This interface is conceptually added to the list of required interfaces on the resulting rowset, and the method fails (E_NOINTERFACE) if that interface cannot be supported on the resulting rowset.
ppObject
[out]
A pointer to memory in which to return the interface pointer. If GetSpecification fails, it must attempt to set *ppObject to a null pointer.
Return Code
S_OK
The method succeeded.
E_FAIL
A provider-specific error occurred.
E_NOINTERFACE
The view did not support the interface specified in riid.
E_OUTOFMEMORY
The provider was unable to allocate sufficient memory in which to return the object information.
Comments
GetSpecification adds a reference count to the object. The consumer must call Release in order to release the reference count when it is no longer needed.
