Hector,

>>> how to lock a file (fstream) for reading/writing

Are you trying to lock the _file_ on disk for all applications running on the system?  Or, are you trying to lock a stream opened to that file for different threads in your application?

In the first case, you need to use an OS-level lock, not Boost.  In the second case, use a mutex as someone else suggested.
