Environment Change Notifier Overview

Notifies a program of changes in the system environment relating to time, locale, power, and thread death.

Programs can use this API to request to be informed of the following changes:

• change of system locale

• system time passes midnight

• system time changes

• any thread dies

• status of the power supply changes

Requests are made through an active object that calls a call back function (encapsulated in a TCallBack) when a change occurs. The class is CEnvironmentChangeNotifier. The TChanges enum lists the possible events.
