Opening Landmarks database

CPosLandmarkDatabase* db = CPosLandmarkDatabase::OpenL();
CleanupStack::PushL(db);
ExecuteAndDeleteLD(db->InitializeL());
CPosLmItemIterator* iter = db->LandmarkIteratorL();
CleanupStack::PushL(iter);
TPosLmItemId lmID;
while ((lmID = iter->NextL()) != KPosLmNullItemId)
    {
    CPosLandmark* lm = db->ReadLandmarkLC(lmID);    
    CleanupStack::PopAndDestroy(lm);
    }
CleanupStack::PopAndDestroy(2, db);

Reading Landmarks from database

CPosLmCategoryManager* categoryManager = CPosLmCategoryManager::NewL(*aDb);
CleanupStack::PushL(categoryManager);
CPosLmItemIterator* iter = categoryManager->CategoryIteratorL();
CleanupStack::PushL(iter);
TPosLmItemId catID;
while ((catID = iter->NextL()) != KPosLmNullItemId)
    {
    CPosLandmarkCategory* cat = categoryManager->ReadCategoryLC(catID);
    CleanupStack::PopAndDestroy(cat);
    }
CleanupStack::PopAndDestroy(2, categoryManager);
