IDirectSound3DBuffer::SetAllParameters

HRESULT SetAllParameters(

LPDS3DBUFFER lpDs3dBuffer, DWORD dwApply);

Sets all 3D sound buffer parameters from a given DS3DBUFFER structure that describes all aspects of the sound buffer at a moment in time.

·Returns DS_OK if successful, or DSERR_INVALIDPARAM otherwise.

lpDs3dBuffer

Address of a DS3DBUFFER structure containing the information that describes the 3D characteristics of the sound buffer.

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.
