UO.ScanItems
From OpenEUO
local nCnt = UO.ScanItems(bVisibleOnly)
Scans all objects in client memory and returns the number of items found. Invisible objects may be excluded using the sole parameter. Once objects are scanned, their parameters are discovered by iterating over the UO.GetItem command, increasing the index from 0 to nCnt - 1.
