IDirectSound3DBuffer::GetConeAngles
The IDirectSound3DBuffer::GetConeAngles method retrieves the inside and outside angles of the sound projection cone for this sound buffer.
HRESULT GetConeAngles(
LPDWORD lpdwInsideConeAngle,
LPDWORD lpdwOutsideConeAngle
);
Parameters
lpdwInsideConeAngle and lpdwOutsideConeAngle
Addresses of variables that will contain the inside and outside angles of the sound projection cone, in degrees.
Return Values
If the method succeeds, the return value is DS_OK.
If the method fails, the return value may be DSERR_INVALIDPARAM.
Remarks
The minimum, maximum, and default cone angles are defined in Dsound.h as DS3D_MINCONEANGLE, DS3D_MAXCONEANGLE, and DS3D_DEFAULTCONEANGLE.
