ListSupportedFeatures() causes the passed in array to be filled with the Uids of supported features. It returns:

  • KErrNone if the RFeatureArray was successfully filled with Uids,

  • KServerBusy if the call failed because features were being enabled or disabled (so creating a lock), and

  • otherwise returns an error code.
