NAMEglutDisplayFunc — Sets the Display callback for the current window.
LIBRARY
OpenGLUT - windowcallback
SYNOPSIS
#include <openglut.h>
void
glutDisplayFunc(void( *callback )( void ));
PARAMETERS
callback Client function for normal redisplay event.
DESCRIPTION
Sets the display callback for the current window . All windows,
including subwindows, must have a display callback registered. OpenG‐
LUT will call the callback function whenever it thinks that the window
may require updating.
This callback is bound to the current window .
CAVEATS
Unlike most callbacks, it is illegal to try to disable the display call‐
back by setting it to NULL .
Multiple redisplays may be coalesced into a single event for invoking the
callback only once.
