IRDPSRAPIAudioStream::GetBuffer method

Gets audio data from the buffer. This method locks an internal buffer and returns a pointer to a specific location in that buffer. It does not allocate a copy of the buffer for the caller. To release the buffer after the last call to this method, call the FreeBuffer method.

Syntax

HRESULT GetBuffer(
  [out, size_is(, *pcbData)] BYTE   **ppbData,
  [out]                      UINT32 *pcbData,
  [out]                      UINT64 *pTimestamp
);

Parameters

ppbData [out]

A pointer to the current location in the buffer.

pcbData [out]

The size in bytes of the available data in the buffer.

pTimestamp [out]

The time-based location of the location pointer.

Return value

If the method succeeds, the return value is S_OK. Otherwise, the return value is an error code.
