title: Read from a continuously growing text file C++ in real time
body: <p>I went through all the answers that were available regarding real-time reading a text file but none seems to work.
  In my program 1 have a continuously growing text file being written by a hardware which is giving two coordinates (two columns).
  In program 2, I want to read those coordinates in real time and move another hardware to the coordinates that are being written.
  The biggest problem is I want to work with shortest possible delay (under 50ms).
  I tried notepad++, but its refresh rate is 3 seconds which is too much.
  Can anyone tell how can this be done?</p>
