How to create a fullscreen OpenGL-ES renderview in Windows?

Question

I'm using cocos2d-x to develop an iPhone game and then it just came to my head why not release my game for PC too? The only problem is that setting the window to full screen mode is not implemented yet. Now I'm just stuck with how to create a full screen window? There are some window creation functions that are used but I'm not sure which one and how I should change.

There is the eglCreateWindowSurface function that cocos2d is calling to create a window. I'm not sure which option I should change so that it creates a full screen window. It would also be nice if I can implement a function that switches my game to full screen mode and back while running.
