To what? I only have a FILE* and I can't get an io object from it, as
far as I can tell.

Indeed, I do know what :-) I'll have a look at how you did it. Thanks.

Agreed. I've been frustrated by this one before. On the one hand,
being able to encapsulate objects tightly, so people can't spoof your
library, is good. But on the other hand, it means you are in trouble
if people have requirements you didn't anticipate.
