Something's odd here. ftell returns long int, so the ftello
substitute needs to worry about overflow only on hosts where long int
is wider than off_t. But I don't know of any such hosts and don't
expect that there will ever be any. Surely on Tru64 both types are
64-bit.
How about this alternative instead?
static inline off_t
ftello (FILE *stream)
{
return ftell (stream);
}
