IDirectSound3DBuffer::SetMinDistance
HRESULT SetMinDistance(
D3DVALUE flMinDistance, DWORD dwApply);
Sets the current minimum distance value.
·Returns DS_OK if successful, or DSERR_INVALIDPARAM otherwise.
flMinDistance
New minimum 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 minimum distance value is 1.0 (corresponding to 1.0 meter at the default distance factor of 1.0 m per unit). For additional information about minimum and maximum distances, see Minimum and Maximum Distance Values.
