I think that this is feasible, but only with considerable effort, and in an
implementation specific way. FILE is an abstraction allowing to be used for
a variety of backends (console, file, port, ...); I'd be surprised of a
backend such as what you have in mind would not be possible.

But I'd consider using C++ streams instead. Here, doing what you want could
be mostly done in a defined, well documented way: Simply write a streambuf
class that writes its characters into the edit control instead of, say, to
a file.
