[semi-OT] stdio question

[Adam D. Moss]

Hi.

I was wondering whether there's a way (ideally ANSI C) to get
the size of an already-open FILE*.  fstat and friends require
an int fd or (ick) a file name, neither of which I believe can
in any remotely standard way be derived from the FILE*.

This is a bit of a sticking point in the abs-file.h contrib,
where I want to provide a way to get a file's size from its handle
(primarily but not exclusively to implement full fseek() semantics
for a seekable vorbis callback) from both PhysicsFS and buffered
stdio via the same thin API.  If not then I simply have to mildly
break the abs-file API (likely not a real problem).

Thanks,
--Adam
