Microsoft Speech Platform
ISpStreamFormat::GetFormat
ISpStreamFormat::GetFormat passes back the cached format of the stream.
The Speech Platform uses this data to determine how to handle the stream data present in the underlying IStream.
<pre IsFakePre="true" xmlns="http://www.w3.org/1999/xhtml"> <strong>HRESULT GetFormat(</strong> <strong> GUID</strong> *<em>pguidFormatId</em>, <strong><a runat="server" href="jj127893(v=msdn.10).md">WAVEFORMATEX</a></strong> **<em>ppCoMemWaveFormatEx</em> <strong>);</strong> </pre>
Parameters
- pguidFormatId
Address of a pointer to GUID data object that receives the format of the stream being used. This is typically either SPDFID_Text or SPDFID_WaveFormatEx. - ppCoMemWaveFormatEx
Address of a pointer to a WAVEFORMATEX data structure that receives the WAV file format information. This is only applicable when the return GUID is SPDFID_WaveFormatEx. The implementer of this interface allocates the memory for the WAVEFORMATEX data structure using CoTaskMemAlloc, but it is the caller's responsibility to call CoTaskMemFree on the returned WAVEFORMATEX pointer.
