IDirectSound3DBuffer::GetConeOrientation

The IDirectSound3DBuffer::GetConeOrientation method retrieves the orientation of the sound projection cone for this sound buffer.

HRESULT GetConeOrientation(
  LPD3DVECTOR lpvOrientation  
);
 

Parameters

lpvOrientation

Address of a D3DVECTOR structure that will contain the current orientation of the sound projection cone. The vector information represents the center of the sound cone.

Return Values

If the method succeeds, the return value is DS_OK.

If the method fails, the return value may be DSERR_INVALIDPARAM.

Remarks

This method has no effect unless the cone angle and cone volume factor have also been set. The default value is (0,0,1).

The values returned are not necessarily the same as those set by using the IDirectSound3DBuffer::SetConeOrientation method. DirectSound adjusts orientation vectors so that they are at right angles and have a magnitude of <= 1.0.
