HRESULT SetAllParameters(
  LPCDS3DLISTENER pcListener, 
  DWORD dwApply 



Address of a DS3DLISTENER structure that contains information describing all 3-D listener parameters.

Value Description
DS3D_DEFERRED Settings are not applied until the application calls the IDirectSound3DListener8::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 3-D coordinates for all 3-D sound buffers.

Return Values

If the method succeeds, the return value is DS_OK.

If the method fails, the return value may be DSERR_INVALIDPARAM.
