How do I set the close operation on a GLUT program written in C? (as in the red button in the top left corner to work)

Question

I'm writing a really simple program using GLUT and C in XCode 4.2.

int main(int argc, char** argv)
{
    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGBA | GLUT_DOUBLE | GLUT_DEPTH);
    glutInitWindowSize(640, 480);

    glutCreateWindow("GLUT Program");

    glutDisplayFunc(display);
    glutReshapeFunc(reshape);
    glutIdleFunc(idle);

    glutMainLoop();
    return EXIT_SUCCESS;
}

When the window opens up, I can't close it via the red button in the top left corner (Mac) because it is grayed out. If any Java programming I've done is a model, there should be some function that sets the close operation so that the red exit button works. I also can't seem to find the documentation for the most recent version of GLUT. Whenever I google it I seem to get OpenGL documentation, which makes me a little more confused then I was on the relationship between the two (I thought GLUT was a cross-platform interface to interact with OpenGL).

I honestly don't know. As I understand, that stuff is included in the distributions of XCode and OpenGL is in the System Updates. So I am using whatever is packaged in with XCode 4.2 and Lion. — Eric Thoma, Jan 03 '12 at 22:52

On Mac OS, the window cannot be closed and the application has to be quit instead (sources here).

Using the GLUT bindings for python on OS X, I find passing an event handler to glutWMCloseFunc is enough to give an action (apparently this is deprecated in favour of glutCloseFunc, but not with my version).

If you want to use the Mac's windowing system to write a native Mac-like application (and you should - your users will thank you!), you should be using NSOpenGLView instead of GLUT. There's some good sample code here.
