What I'm saying is that if we have not got fseeko then we should use any
'seek-class' function that returns a 64 bit value. We have already made the
assumption that off_t is an integer; the same logic that came to that
conclusion, applies just as validly to the other seek functions.
Secondly, if there is no 64 bit 'seek-class' function, then we should
probably use a size_t, but a long would probably be fine too. I am not
particularly attached to this part; long, int etc etc. Whatever is most
likely to return an integer and work with whatever function we choose.
As to implications: assuming they are all integers (which as you know I
don't like), we should have no problems.
If a system does not have any function to access 64 bit file offsets, then
I'd say they are pretty unlikely to have files > 2GB.
