I need to delete the selected items in my browserdata.
Here is the way I did:

//I got a handle from the API :
Handle handle_selectedItems;
GetDataBrowserItems(browser, kDataBrowserNoItem,
false,
kDataBrowserItemIsSelected,handle_selectedItems);

As Larry said, GetDataBrowserItems() expects an allocated handle (it will resize it to match the number of items returned).

Handle h = ::NewHandle(0);
::GetDataBrowserItems(browser, kDataBrowserNoItem, false, kDataBrowserItemIsSelected, &h);

If I remember correctly, OS X doesn't like handle sizes set to zero. I am not 100% sure about this
