ISpStream::SetBaseStream

ISpStream::SetBaseStream initializes the ISpStream object with the format of the IStream and an object to encapsulate.

  
    HRESULT SetBaseStream(
    IStream                *pStream,
    REFGUID                 rguidFormat,
    const WAVEFORMATEX     *pWaveFormatEx
);

Parameters

  • pStream
    Address of the IStream containing the base stream data.
  • rguidFormat
    The data format identifier associated with the stream.
  • pWaveFormatEx
    Address of the WAVEFORMATEX structure that contains the wave file format information. If guidFormatId is SPDFID_WaveFormatEx, this must point to a valid WAVEFORMATEX structure. For other formats, it should be NULL.

Return values

Value

Remarks

The helper class CSpStreamFormat and the SPSTREAMFORMAT enumeration can be used to avoid the possibility of typos or mistakes when filling in the WAVEFORMATEX structure.
