Subject: e2fsprogs bmap problem

I am running into a problem with the output of the function ext2fs_bmap in the ext2fs library version 1.41.5: when I send it an inode structure pointer as the third argument and the number of a deleted inode as the second argument, it seems to end up trying to read the deleted inode from disk (and results in the returned value block number being 0), when I expected it to just get the values from the inode structure I send to it.  This only happens if the inode contains an extent structure within it; when it has the indirect block structure it behaves as I expected.

I couldn't find the documentation for this function, so is this the right behavior for this function?  If so, is there a better way to retrieve the block numbers pointed to by an inode structure provided by the ext2fs library?

Thanks,
N
