I think it works, but it's hardly officially sanctioned.

They are FILE*'s. The standard IO streams are defined to be expressions
of type FILE*, which they are; they are not defined to be objects. This
is why the standard provides freopen(). Yes, some of the Unixy standards
are extending this, but I have not seen much in the way of legitimate reasons
to do this instead of using freopen(). (There are some, but they're so
inherently unportable that it hardly matters.)
