IDirectSound3DBuffer::SetMaxDistance

HRESULT SetMaxDistance(

D3DVALUE flMaxDistance, DWORD dwApply);

Sets the current maximum distance value.

·Returns DS_OK if successful, or DSERR_INVALIDPARAM otherwise.

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 3D coordinates for all 3D sound buffers.

By default, the maximum distance value is infinite. For additional information about minimum and maximum distances, see Minimum and Maximum Distance Values.
