To clarify this. Your application is made up from several processes and
you want to implement locking between those or do you want to lock
against completely unrelated processes?
For the first case you can use boost.interprocess for the second case i
don't see a portable solution as for example POSIX systems are
implementing advisory locking (as opposed to mandatory locking on
Windows). On such system you can only have locking between cooperating
processes which are obeying to a locking protocol.
