title: Linux file renaming deletion
body: <p>Is it possible to prevent file deletion/renaming while program has opened file descriptor. I open file with open() and then try locking it with fcntl() but i still can rename or delete file. Reading fcntl documentation it seems imposible to do.</p>
  
  <pre><code>FD = open(file_name, O_WRONLY | O_CREAT | O_EXCL, 0600);
  struct flock exclusiveLock;
  exclusiveLock.l_type=F_WRLCK;
  exclusiveLock.l_whence=SEEK_SET;
  exclusiveLock.l_len=exclusiveLock.l_start=0;
  exclusiveLock.l_pid=0;
  lockResult=fcntl(FD,F_SETLK,&amp;exclusiveLock);
  </code></pre>
