  14. Hi,
  15.  
  16. I'm trying to make a small program in C handling a directory. open it and print it's content
  17. :
  18.  
  19.  
  20. The problem is it can't read it ! Why ? I 've set the mode to a+rwx to that direstory !
  21.  
  22. These are the code and if you know what's the problem please tell me why ?
