title: find inode number of a file using C code
body: <p>I have program, say name giverootAccess. This program can receive a file name in the current directory (where giverootAccess resides) as a command-line argument. Then the file will get the root access. The file can be an executable or a shell script.</p>
  
  <p>Now the problem is that, A hacker can get root access by redirecting the request to bash. I want to restrict a user to give root access only on those files inside the directory where giverootAccess resides.  hacker can redirect file name to unwanted programs and hence get the root permission.</p>
  
  <p>So I need a mechanism to uniquely identify a file, not by its name (as it can be mimicked and hacked). Is inode can be used for this purpose? </p>
  
  <p>My plan is, when the application installs, I will store the inodes of all the files in the directory and whenever somebody runs the giverootAccess with a file name, I will check the file name and its inodes are matching with stored one. If matching, then only giverootAccess program actually give root access to the file.</p>
  
  <p>Do you have any other simple mechanism to do this job ?</p>
