IStiUSD::UnLockDevice method (stiusd.h)
A still image minidriver's IStiUSD::UnLockDevice method unlocks a device that was locked by a previous call to IStiUSD::LockDevice.
Syntax
HRESULT UnLockDevice();
Return value
If the operation succeeds, the method should return S_OK. Otherwise, it should return one of the STIERR-prefixed error codes defined in stierr.h.
Remarks
If a driver's IStiUSD::LockDevice method called CreateFile, then IStiUSD::UnlockDevice should call CloseHandle.
