ITCDeviceClose
This function closes the interface opened with ITCDeviceOpen.
Syntax:
HRESULT ITCDeviceClose( IUnknown** ppvObject );
Parameters
ppvObject [in,out] A pointer to the interface pointer created by
ITCDeviceOpen. If successful on output, this
pointer is set to NULL.
Return Values
None.
Remarks
On Windows, this interface decrements the reference count. So alterna-
tively, IUnknown::Release() could be used and must be used if reference
counting is performed with IUnknown::AddRef(). On DOS, this function
closes all resources associated with the channel.
