The GetConeAngles method retrieves the inside and outside angles of the sound projection cone.
HRESULT GetConeAngles( LPDWORD pdwInsideConeAngle, LPDWORD pdwOutsideConeAngle );
Addresses of a variable that receives the inside angle of the sound projection cone, in degrees. This is the angle within which the sound is at its normal volume.
Addresses of a variable that receives the outside angle of the sound projection cone, in degrees. This is the angle outside of which the sound is at its outside volume.
If the method succeeds, the return value is DS_OK.
If the method fails, the return value may be DSERR_INVALIDPARAM.
The minimum, maximum, and default cone angles are defined in Dsound.h as DS3D_MINCONEANGLE, DS3D_MAXCONEANGLE, and DS3D_DEFAULTCONEANGLE.
