IDirectSound3DBuffer::SetMaxDistance

The IDirectSound3DBuffer::SetMaxDistance method sets the current maximum distance value.

HRESULT SetMaxDistance(
  D3DVALUE flMaxDistance,  
  DWORD dwApply            
);
 

Parameters

flMaxDistance

New maximum distance value.

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.

Remarks

The default maximum distance, defined as DS3D_DEFAULTMAXDISTANCE, is effectively infinite.
