property OnCloseKeyHandle : TCBProcCloseKeyHandleEvent;
TCBProcCloseKeyHandleEvent = procedure( Sender : TObject; UserContext: pointer; KeyHandle: THandle; KeyHandleContext: pointer; Error: LongWord ) of object;
- Sender - reference to the class that called the delegate/event handler
- UserContext - the placeholder for the application-defined data
- KeyHandle - handle of the key to be closed
- KeyHandleContext - the placeholder for the application-defined data set in On*CreateKey or On*OpenKey together with the key handle
- Error - contains the error code if the error happened during the use of the application-provided key
The callback/event is used to ask the application to close an application-provided handle passed from the CBProcPreCreateKeyEvent or CBProcPreOpenKeyEvent callbacks.
