IDirectSound3DBuffer::SetAllParameters

The IDirectSound3DBuffer::SetAllParameters method sets all 3-D sound buffer parameters from a given DS3DBUFFER structure that describes all aspects of the sound buffer at a moment in time.

HRESULT SetAllParameters(
  LPCDS3DBUFFER lpcDs3dBuffer,  
  DWORD dwApply                 
);

Parameters

lpcDs3dBuffer

Address of a DS3DBUFFER structure containing the information that describes the 3-D 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 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.

Requirements

  Windows NT/2000: Requires Windows 2000.
  Windows 95/98: Requires Windows 95 or later. Available as a redistributable for Windows 95.
