glutIdleFunc - Man Page
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.
