Extracting block pointer list -- ffsinfo?

[Jamie Ostrowski]

    I'm a student studying filesystems, and I'd like to find a way to list
the block pointers in an inode. Are there any tools in FreeBSD that can do
that? For example, I've tried the following command, but I'm not seeing a
list of the block pointers:

ffsinfo -i 2 -l 256 /dev/da0s1f
