NAME
glutCreateWindow -- Create a new top-level window
LIBRARY
OpenGLUT - window
SYNOPSIS
#include <openglut.h>
int
glutCreateWindow(const char* title);
PARAMETERS
title Title for created window
DESCRIPTION
This function sends a request for a window to be constructed. OpenGLUT immediately constructs a data structure to track further events with
the window, on the theory that eventually the window manager will get back to us with a real window. This allows us to begin registering
callbacks immediately.
In fact, you must register a display callback via glutDisplayFunc() before you enter glutMainLoop().
For onscreen windows, you should not depend upon the window concretely existing or being visibile until you are told that it exists and is
visible via a registered callback.
The return value is an int. It should be positive for valid windows or 0 if failure occurred for some reason (Though traditional GLUT
tends to bail out and abort rather than returning errors.) The integer is your window id . Old GLUT promises that these integers are
``small''; we do not reuse old id s, but do produce them sequentially.
You can change the title later via glutSetWindowTitle().
