title: How to stop or pause glutTimerFunc in GLUT?
body: <p>In my project i'm running a train which stops moving when it reaches a particular point this moving is carried out by glutTimerFunc .I once again want the train to start from the location where i click my mouse to a particular location 
                              BUT THE PROBLEM HERE IS,
  My timer still running even after reaching that location,so even when i initialise the starting point its not working(it continues from the left location).</p>
  
  <p>Now i need to stop the timer and start the train timer for the new location.</p>
