Reading Ext4 Inode

[ssurampu]

Hi,

I am writing code to open ext4 partition understand superblock, gds and start reading individual inode entries.

In new Ext4 group descriptor structure (ext4_group_desc) there are two fields bg_inode_table_lo and bg_inode_table_hi.

How can I read inode using these tow fields.

For ext3 there is only bg_inode_table which gives location to read inode data.

Please help.

Thanks & Regards,
sridhar.

adding more to my above query.

I am trying to read all inodes of a ext4 superblock.

I could able to read superblock, group descriptros.

8192 inodes are stored in each block group.
I could able to extract inodes upto 8000 using first group descriptor table.

but I couldn't able to read inode from 8193

I could see group descriptor table is correct but.
Could you please help in this...

What your are trying to achieve? Did you tried ext2lib?
