IStiDeviceControl::Release method (stiusd.h)
The IStiDeviceControl::Release method closes the instance of the COM object that was created when a minidriver client called IStiUSD::Initialize.
Syntax
ULONG Release();
Return value
If the operation succeeds, the method returns S_OK. Otherwise, it returns one of the STIERR-prefixed error codes defined in Stierr.h.
Remarks
The IStiDeviceControl::Release method should be called from within the destructor function of a user-mode still image minidriver's IStiUSD interface. (For more information, see Creating a User-Mode Still Image Minidriver.)
A still image minidriver receives an IStiDeviceControl interface pointer as input to its IStiUSD::Initialize method.
