GLUTIDLEFUNC(3)

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.
