That's possible only if the wrapper is part of stdio, because fpos_t is

Like the Linux one. Hmm, @gnu.org...coincidence? :-)
Please, no. I've written glue to run code designed for funopen() using
fopencookie; while I haven't written it, I've sketched out how to do
the converse. Implementing funopen with fopencookie is annoying (it
costs an extra malloc on stream open, free on close, and one more
function call for each method operation on the stream); the converse is
trivial. Which way is easier to write glue for is a fairly clear
indication which interface is preferable.

How does an ops struct do that? You still have an API flag day
whenever you change the ops struct, which is just a somewhat obscured,
inconvenient, and textually separate version of the arglist to funopen.
