CreateStreamOverRandomAccessStream function
Creates an IStream around a Windows Runtime IRandomAccessStream object.
Syntax
HRESULT STDAPI CreateStreamOverRandomAccessStream(
_In_ IUnknown *randomAccessStream,
_In_ REFIID riid,
_Out_ void **ppv
);
Parameters
- randomAccessStream [in]
-
The source IRandomAccessStream.
- riid [in]
-
A reference to the IID of the interface to retrieve through ppv, typically IID_IStream. This object encapsulates randomAccessStream.
- ppv [out]
-
When this method returns successfully, contains the interface pointer requested in riid, typically IStream.
Return value
If this function succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
Remarks
We recommend 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 in riid that could lead to unexpected results.
