The SetMaxDistance method sets the maximum distance value.
Syntax
HRESULT SetMaxDistance(
D3DVALUE flMaxDistance,
DWORD dwApply
);
Parameters
flMaxDistance
New maximum distance value. D3DVALUE is defined as float in D3dtypes.h.
dwApply
Value that specifies when the setting should be applied. This value must be one of the following:
| Value | Description |
| DS3D_DEFERRED | Settings are not applied until the application calls the IDirectSound3DListener8::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.
Requirements
Header: Declared in dsound.h.
