The IDirectSound3DBuffer::GetMode method retrieves the current operation mode for 3-D sound processing.
HRESULT GetMode(
LPDWORD lpdwMode
);
Parameters
lpdwMode
Address of a variable that will contain the current mode setting. This value will be one of the following:
DS3DMODE_DISABLE
Processing of 3-D sound is disabled. The sound seems to originate from the center of the listener's head.
DS3DMODE_HEADRELATIVE
Sound parameters (position, velocity, and orientation) are relative to the listener's parameters. In this mode, the absolute parameters of the sound are updated automatically as the listener's parameters change, so that the relative parameters remain constant.
DS3DMODE_NORMAL
Normal processing. This is the default mode.
Return Values
If the method succeeds, the return value is DS_OK.
If the method fails, the return value may be DSERR_INVALIDPARAM.
