GLUTGETWINDOWDATA(3)             Local Manual             GLUTGETWINDOWDATA(3)

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.
