OnMultimediaChanged
OnMultimediaChanged is called by ADLX when multimedia settings change.
Syntax
Copied!
adlx_bool OnMultimediaChanged (IADLXMultimediaChangedEvent * pMultimediaChangedEvent)Parameters
-
[in]pMultimediaChangedEvent IADLXMultimediaChangedEvent * The pointer to a multimedia settings change event.
Return Value
If the application requires ADLX to continue notifying the next listener, true must be returned.
If the application requires ADLX to stop notifying the next listener, false must be returned.
Remarks
Once the application registers to the notifications with AddMultimediaEventListener , ADLX will call this method until the application unregisters from the notifications with RemoveMultimediaEventListener . The method should return quickly to not block the execution path in ADLX. If the method requires a long processing of the event notification, the application must hold onto a reference to the multimedia settings change event with Acquire and make it available on an asynchronous thread and return immediately. When the asynchronous thread is done processing it must discard the multimedia settings change event with Release .
