With recent versions of the library you can use an extension, fstream::fd(),
to obtain the underlying file descriptor.

Or you could extend fstream (or one of the buffer classes) to do the
locking for you at appropriate times. That way the "non-standard-ness"
would be explicitly in your code, rather than depending on a particular
library extension.
