In my OpenGL program, in order to run it in fullscreen mode, I'm using the GLUT function glutGameModeString(const char *string).
(where 'string' specifies the screen width,height,pixelDepth and refresh rate)

To make it working in any system,i need to dynamically determine the screen width and screen height of the host system, prior to making the call to 'glutGameModeString' function.
How do I do that?

(I just need to know how to retrieve the screen height and width in windows)
