void FindVehicleOnPos ( TileIndex  tile,
void *  data,

Note:
The return value of proc will be ignored.
Use this function when you have the intention that all vehicles should be iterated over.
Parameters:
tile The location on the map
data Arbitrary data passed to proc.
proc The proc that determines whether a vehicle will be "found".
