The following:
dev_end = lseek(fd, 0, SEEK_END);
Returns the file size or the device size (if a disk or disk partition)
on my Sun running SunOs 5.5.1.

On Linux machines of various versions, including the latest, it returns
zero (0). I do not know what is correct. However, if POSIX requires the
observed behavior, I think we no longer have a generic means of finding
out the size of a disk device or disk partition. This is not good.

It does return the file size if the object is a file. However, if
it is a disk or disk partition, it does not.
