IDirectSound3DBuffer::GetConeOutsideVolume
The IDirectSound3DBuffer::GetConeOutsideVolume method retrieves the current cone outside volume for this sound buffer.
HRESULT GetConeOutsideVolume(
LPLONG lplConeOutsideVolume
);
Parameters
lplConeOutsideVolume
Address of a variable that will contain the current cone outside volume for this buffer.
Return Values
If the method succeeds, the return value is DS_OK.
If the method fails, the return value may be DSERR_INVALIDPARAM.
Remarks
Volume levels are represented by attenuation. Allowable values are between DSBVOLUME_MAX (no attenuation) and DSBVOLUME_MIN (silence). The default value is DS3D_DEFAULTCONEOUTSIDEVOLUME (no attenuation). These values are defined in Dsound.h. Currently DirectSound does not support amplification.
