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.
