NAME
     glutIdleFunc -- Sets the global idle callback.

LIBRARY
     OpenGLUT - idletimer

SYNOPSIS
     #include <openglut.h>

     void
     glutIdleFunc(void( *callback )( void ));

PARAMETERS
      callback	   Client function for idle event.

DESCRIPTION
     When OpenGLUT's glutMainLoop() is doing nothing else, it checks to see if an ``idle'' callback set.  If so, OpenGLUT invokes that callback.

     This callback is  not   bound to any window.

CAVEATS
     There is at most  one   idle callback for your entire application.
