Windowing after glutFullScreen

I’m trying to make a program for a computer I don’t know much about, so I don’t want to use game mode in case I over shoot the screen size.

To go fullscreen I use glutFullScreen. My question is how do I bring it back to windowed mode?


with more searching in glut.h I found using glutReshapeWindow does and you can reposition it using glutPositionWindow.

thanks anyways
