NAME

glutGetWindow - Return the current window identifier, 0 if undefined  

LIBRARY

OpenGLUT - window  

SYNOPSIS

In openglut.h Ft int Fn glutGetWindow void  

DESCRIPTION

glutGetWindow() returns the Bf Li
 window id Ef
  of the Bf Li
 current window Ef
 .  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 Bf Em
 not Ef
  stack-related!)

One cause for the function to return 0 is if you have called glutDestroyWindow() on the Bf Li
 current window Ef
  and have done nothing to set a new window as current.
