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.
