GLUTGETWINDOW(3) Library Functions Manual (local) GLUTGETWINDOW(3)

NAME

glutGetWindowReturn 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.
