Tizen Developers

How can I show a UI application over the lock screen  using the new SDK.
I found below but it is for 2.2.1. I need it for the latest SDK I mean Tizen 2.3. Please help.

if (Tizen::Shell::LockManager::GetInstance()->IsLocked())
{
   // 'http://tizen.org/privilege/uimanager' platform privilege required
   pAppFrame->SetZOrderGroup(WINDOW_Z_ORDER_GROUP_HIGH);
}
