User space tool to extract ext3 inode information

I need to write a user space tool that can dump
logical block addresses used by every file in a ext3
file system. For example, if file foo uses LBAs 2,3
and file bar uses LBAs 100,102,156, then the ouptut
should read:

foo         2, 3
bar         100,102,156

Is there a tool that exists that can do this? If not,
what would be a good strategy to write this tool. I am
learning filesystem programming and would really
appreciate any pointers.

thanks in advance!!
