Creates a Windows Runtime random access stream around an IStream base implementation.
HRESULT STDAPI CreateRandomAccessStreamOverStream( _In_ IStream *stream, _In_ BSOS_OPTIONS options, _In_ REFIID riid, _Out_ void **ppv );
- stream [in]
The COM stream to encapsulate.
- options [in]
- riid [in]
A reference to the IID of the interface to retrieve through ppv, typically IID_RandomAccessStream.
- ppv [out]
When this method returns successfully, contains the interface pointer to the RandomAccessStream that encapsulates stream requested in riid.
If this function succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
For info on utility classes that help with interoperation between Windows Runtime and COM streams, see the Remarks at RandomAccessStreamOverStream.
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.
