NAME
glutGetWindow -- Return the current window identifier, 0 if undefined
LIBRARY
OpenGLUT - window
SYNOPSIS
#include <openglut.h>
int
glutGetWindow(void);
DESCRIPTION
glutGetWindow() returns the window id of the current window . This is useful, e.g., if you have a generic function that is used with
several windows and it needs to temporarily change to another window. (There is no window stack for you to use with pushes and pops. Do not
be confused by glutPushWindow() and glutPopWindow(); those pushes and pops are not stack-related!)
One cause for the function to return 0 is if you have called glutDestroyWindow() on the current window and have done nothing to set a new
window as current.
