Can somebody clue me in about inodes on an RS6000 running AIX 3.1?

[Roy Mongiovi]

I'm trying to write a program to read the contents of a file from the raw
filesystem given its inode number.  I've figured out how to do this on Dynix
(Sequent), SunOS, and IRIX (SGI).  Now I'm trying to port it to AIX and the
journalled filesystem.

I've tried using the "itod" and "itoo" macros from /usr/include/sys/sysmacros.h
but "itod" (at least) does not seem to compute the correct block number.  I've
managed to find the root inode in the raw filesystem, and I've looked at the
next inode (3) which should be the inode for the ".inodes" file.  This inode
is suppoed to represent a file that contains all the filesystem's inodes, but
it contains 0 blocks, is of size 0, and all the disk addresses are 0.

So, anyway, I'm clueless.  Can anyone point me in the right direction?  Thanks.
