/* $Id: ftello.c 3681 2000-07-29 22:55:18Z rra $
**
** Replacement for a missing ftello.
**
** ftello is a version of ftell that returns an off_t instead of a long.
** For large file support (and because it's a more logical interface), INN
** uses ftello unconditionally; if ftello isn't provided by a platform but
** fpos_t is compatible with off_t (as in BSDI), define it in terms of
** fgetpos. Otherwise, just call ftell (which won't work for files over
** 2GB).
