Almost unnoticed went that patch that has been contributed by Ted
Roth, at a time when he had already `retired' from the project.

My only concern about it is that it would constitute an API change for
the stdio API, so all users of the current API would have to change
their sources.  OTOH, we've always threated that API changes might
happen in the preamble of the stdio documentation:


What do people think, is this an acceptable reason for an API change?

I think so, altho I stay away from stdio as much as I can on embedded systems.

As I understand Ted's patch what one gains is control over more than one possible FILE for get() and put(). That would be fairly important for devices with more than one UART. And quite important if one built much of a multisession network protocol stack and hooked it in thru stdio.
