NAME
glutGetWindowData — Get the user data for the current window
LIBRARY
OpenGLUT - window
SYNOPSIS
#include <openglut.h>
void*
glutGetWindowData(void);
DESCRIPTION
This function will return whatever void* value is associated with the
current window via glutSetWindowData(). This is NULL if you did not
associate a pointer with your window. This can be useful in a situation
where you have a single callback function performing services for many
windows. You could keep track of the window id s in a global list
and search for the current window in that list. But this is quicker
than searching a data structure, and allows you to avoid the use of glob‐
als for this.
