The IDsDriver::Closemethod returns the object back to system use, that is, when DirectSound no longer requires use of the IDsDriver::CreateSoundBuffer, IDsDriver::DuplicateSoundBuffer, and IDsDriver::GetCapsmethods.
HRESULT Close( );
Return Values
Returns DS_OK if successful, or DSERR_GENERICotherwise.
Remarks
The driver should deallocate any structures it allocated on the IDsDriver::Opencall, reset the hardware to a known state, and mark the device as unallocated. Once this method has been called, the Wave portion of the driver should be able to acquire the use of the hardware.
This method should not decrement the reference count on the DirectSound driver object. The reference count of an object should only be changed by the IUnknownmembers AddRefand Release.
