-
Type: REFIID
A reference to the IID of the interface to retrieve through ppv, typically IID_IStorage or IID_IStream.
- ppv [out]

When this method returns, contains the interface pointer requested in riid. This is typically IStorage or IStream.
Return value
Type: HRESULT
If this function succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
Remarks
It is recommended that you use the IID_PPV_ARGS macro, defined in Objbase.h, to package the riid and ppv parameters. This macro provides the correct IID based on the interface pointed to by the value in ppv, which eliminates the possibility of a coding error.
