Purpose

Provides miscellaneous low-level -services for notifying programs of environment changes and of thread deaths, -and for putting simple messages on screen.

-
Description

The API has three key concepts: change -notifier, thread-death notifier, and simple screen output service.

Change -notifier

The change notifier signals the requesting thread's request -semaphore when a change in the environment occurs, such as a switch in locale, -or system time being reset.

The change notifier interface is provided -by RChangeNotifier.

Note that the Environment Change -Notifier API provides the same service, wrapped in an active object.

Thread-death notifier

The thread-death notifier signals the -requesting thread's request semaphore when a specified other thread terminates.

The -thread-death notifier interface is provided by RUndertaker.

Simple screen output service

The simple screen output service -allows either a single line message or a simple dialog box to be displayed -on the screen. It is typically used for debug messages.

The simple -screen output service interface is provided by RNotifier, -which also provides access to the UI-specific plug-in notifiers, via the Extended Notifier Framework.
