Win32 and glutDestroyWindow()

[Sisyphus]

Hi,

On Win32 (freeglut-2.4.0), I'm having trouble destroying an existing window.
I have the following snippett:

int window;
glutInit(&argc, argv);
glutInitWindowSize(200, 300);
window = glutCreateWindow("TEST");
glutDestroyWindow(window);

but the window stays open ... from which I deduce that the return value of
glutCreateWindow() is not the appropriate argument to hand over to
glutDestroyWindow(). What *is* the appropriate argument ?

I've provided a full demo below my sig. The "Sleep(3000);" call allows me to
verify that the window stays open until the program exits.

Cheers,
Rob

#include <stdio.h>
#include <windows.h>
#include <GL/freeglut.h>

int main(int argc, char * argv[]) {

int window;

glutInit(&argc, argv);
glutInitWindowSize(200, 300);
window = glutCreateWindow("TEST");
glutDestroyWindow(window);
printf("Window should now have been destroyed\n");
Sleep(3000);

return 0;

}

You need to pump the event loop with glutMainLoopEvent() or
just call glutMainLoop() in order for the GLUT calls to take
effect....
