C Program: Get inode header fields and information by inode number

I need to write a program in C/C++ that request the user to put in an inode number and then return all of the inode header fields and information back. I am not familiar with linux systems and commands at all. I have found some commands and tried different things that didnt work like I needed.

find -inum inodenumber

will give me the path to the file that contains the specified number. All the information I need comes from istat (according to my research) but I cant get it to work. Im doing

istat FILENAME.jpg

I get the response:

Missing image name and/or address usage: istat[-B num] [-f fstype] [-i ingtype] [-b dev_sector_size] [-o imgoffset] [-z zone] [-s seconds] [ivV] image inum ...

What do I need to do?

Try running find with the inode number and then use the filename it generates with stat.

istat only works on disk images, not live filesystems.

There are no system calls in Linux which can look a file up in a live filesystem by its inode number.

Run man istat of course.

In general, you can always get help from the terminal itself by running man.
