[boost] random access file iterators ?

Does anyone know about an implementation of a "random access file iterator"? I.e. an iterator that will allow to access a file via an iterator interface? I know istream and outstream iterators, but these are only output resp. input iterators. I am looking for something that will allow random access too. Thank you for any hints. -- _________________________________________ _ _ | Roland Schwarz |_)(_ | aka. speedsnail | \__) | mailto:roland.schwarz@chello.at ________| http://www.blackspace.at
