HRESULT GetMode(LPDWORD lpdwMode);
Retrieves the current operation mode for 3D sound processing.
·Returns DS_OK if successful, or DSERR_INVALIDPARAM otherwise.
lpdwMode
Address of a variable that will contain the current mode setting. This value will be one of the following:
DS3DMODE_DISABLE
Processing of 3D 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.
