Is there any method/command/utility to know what are the block numbers
which
are allocated to a file in ext2 fs?

You can use debugfs utility. Otherwise if you want to use the API, you
can use FIBMAP.
Google for usage of FIBMAP, you will get it for sure !

The FIBMAP ioctl gives you the block number give an integer, which is
the nth block attached to the inode. It includes blocks allocated to
store indirect blocks too.

What exactly FIBMAP is? and how to use it ?

For instance , if I made my own module and I am using ioctl. Then how should
I use it?

Is it a function?
