title: Reading from a file opened using append mode
body: <p>It might be a very dumb question but I am modifying someone else's code and it seems I need to read from a file that was opened in append mode. I tried to <code>fseek</code> to the beginning of the file but nothing is being read. 
  I know I can change the mode to rw but I wanted to know why <code>fseek</code> is not working. In the man page it does say write ignores <code>fseek</code> but nothing about read though.</p>
