title: Is it possible to read and write in file at the same time?
body: <p>Here's the scenario:</p>
  
  <ul>
  <li>ThreadA is going to read from some socket, and write data to "MyFile.txt"</li>
  <li>ThreadB is going to read "MyFile", and when it reaches the end, it will loops until new data are available in MyFile (because i don't want to re-open "MyFile.txt", and lose the time so i reach the position from where i was..).</li>
  </ul>
  
  <p>Is it possible to do such a thing ?</p>
  
  <p>If not, is there another way to do such a thing ?</p>
