Getting inode no from current process file descriptor table

Getting inode no from current process file descriptor table

[selvakumar nagendran]

Hello,
   How can we get the inode number for a file provided
we have the corresponding file descriptor. Can we use
files_struct -> fd[fd] to get struct file ?. From that
how can we get the corresponding inode number?

Regards,
selva

#include <linux/dcache.h>
#include <linux/file.h>
#include <linux/fs.h>

struct file * file = fget(fd);
inode_number = file->f_dentry->d_inode->i_ino;
fput(file);
