MFCreateMFByteStreamWrapper function (mfapi.h)

Creates a wrapper for a byte stream.

Syntax

HRESULT MFCreateMFByteStreamWrapper(
  [in] IMFByteStream *pStream,
  [in] IMFByteStream **ppStreamWrapper
);

Parameters

[in] pStream

A pointer to the IMFByteStream interface of the original byte stream.

[in] ppStreamWrapper

Receives a pointer to the IMFByteStream interface of the wrapper. The caller must release the interface.

Return value

If this function succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Remarks

The IMFByteStream methods on the wrapper call directly through to the original byte stream, except for the IMFByteStream::Close method. Calling Close on the wrapper closes the wrapper object, but leaves the original byte stream open.
