thanks rajat  but i need it in kernel space.

In the kernel space too idea would be same. You get the directory's
page and depending on the filesystem you advance by a particular
offset in that page. For example look at ext2_readdir() and how it
finds the next entry by
incrementing offsets by ext2_rec_len_from_disk() .

hi all,
is there any way to find out the offset or the directory entry number

of

a
file in the directory ?

let me explain a bit more:

when we open a drectory via open(2) and find out the directory entry

by

quoted

readdir(2,3) or getdents(2) it automatically increases to the next
directory entry and fills in the dirent structure.
but in kernel space , let we have the parent directory name and child

of

quoted

quoted

quoted

it
. so is there any way to figure out at what  offset or what number
(exactly)
that perticular child will occur in the directory contains?
