IDirectSound3DBuffer::SetAllParameters
The IDirectSound3DBuffer::SetAllParameters method sets all 3-D sound buffer parameters from a given DS3DBUFFER structure that describes all aspects of the sound buffer at a moment in time.
HRESULT SetAllParameters(
LPCDS3DBUFFER lpcDs3dBuffer,
DWORD dwApply
);
Parameters
lpcDs3dBuffer
Address of a DS3DBUFFER structure containing the information that describes the 3-D characteristics of the sound buffer.
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.
