Managing the Data Handler

Data handler components provide a number of functions that your application can use to manage its connection to the handler. The most important among these is DataHTask , which provides processor time to the handler. Your application should call this function often so that the handler has enough time to do its work.

Other functions in this category provide playback hints to the data handler and allow your application to influence how the component handles its cached data.

For more information on these functions, see "Managing Data Handler Components" .
