> Why is it ok to seek to 0 bytes and 1 byte, but not 2?

The test-program passed parameters in the wrong order, the correct order is

        lseek(fd, pos, whence)

However, this was not the error I was really trying to fix (the real
program passed the parameters in the correct order). The real problem was
that lseek() fails when doing SEEK_END on a raw device. On Linux and
Solaris, lseek() return 0 when doing SEEK_END on raw devices.

Any comments?
