[Boost-users] iostream and mapped_file

Hello

Is there any example how to use boost::iostream mapped_file ?
I couldnt find any..

Which are the reasons that should make me consider using mapped_file stream?
I want to read my text file as fast as possible (not all at once) - it 
should be seekable..

I know I should open file in binary mode and do read() to fixed size blocks 
to achieve the best preformance, but then I would have problems separating 
lines (I was consider using tokenizer but it would require stl data type so 
I would have to copy data).

Is it possible to solve this problem with using boost::iostream filter so 
that it would be faster than getline()?

Any help is highly appreciated!
Thank you very much
