No, freopen doesn't require a file name, or any of those other things.

"If filename is a null pointer, the freopen function attempts to change
the mode of the stream to that specified by mode , as if the name of the
file currently associated with the stream had been used. It is
implementation-defined which changes of mode are permitted (if any), and
under what circumstances." (C standard, 7.21.5.4p3).

If the implementation you're using fails to support changing text mode
to binary mode, that's hardly the fault of the C standard, that's up to
the implementation.
