IDirectSound3DListener::SetAllParameters
HRESULT SetAllParameters(
LPDS3DLISTENER lpListener, DWORD dwApply);
Sets all 3D listener parameters from a given DS3DLISTENER structure that describes all aspects of the 3D listener at a moment in time.
·Returns DS_OK if successful, or DSERR_INVALIDPARAM otherwise.
lpListener
Address of a DS3DLISTENER structure that contains information describing all current 3D listener parameters.
dwApply
Value indicating when the setting should be applied. This value must be one of the following:
DS3D_DEFERRED Settings are not applied until the application calls the IDirectSound3DListener::CommitDeferredSettings method. This allows the application to change several settings and generate a single recalculation.
DS3D_IMMEDIATE Settings are applied immediately, causing the system to recalculate the 3D coordinates for all 3D sound buffers.
