The TcCloseInterface function closes an interface previously opened with a call to TcOpenInterface. All flows and filters on a particular interface should be closed before closing the interface with a call to TcCloseInterface.
DWORD TcCloseInterface ( HANDLE IfcHandle );
| Error code | Description |
|---|---|
| NO_ERROR | The function executed without errors. |
| ERROR_INVALID_HANDLE | The interface handle is invalid. |
| ERROR_TC_SUPPORTED_OBJECTS_EXIST | Not all flows have been deleted for this interface. |
Regardless of whether TcCloseInterface is called, an interface will be closed following a TC_NOTIFY_IFC_CLOSE notification event. If the TcCloseInterface function is called with the handle of an interface that has already been closed, the handle will be invalidated and TcCloseInterface will return ERROR_INVALID_HANDLE.
Note Use of TcCloseInterface requires administrative privilege.
