Determining if an API is Ready (Windows CE 5.0)
In earlier versions of Windows CE, if a component or module depended on an API set being registered, the component or module used the IsAPIReady function. This API returns TRUE or FALSE depending on whether the API set was registered. The main problem with the API was that dependent API sets might never have been registered if the module that registered them was not part of the OS design. Another problem was that some components ended up polling and waiting for the transition so that these components could display a user interface, for example.
The methodology used by the registry can be used in other parts of the OS to trigger waiting applications.
