There are other problems. fgetpos() expects a pointer to an fpos_t,
while ftello just returns off_t, so you need a local variable in the
function to pass to fgetpos() and they return that from the function.
It is much cleaner to just duplicate the entire API so you don't have
any limitations or failure cases.
