NAME
       glutSpaceballRotateFunc - sets the Spaceball rotation callback for the current window.

SYNTAX
       void glutSpaceballRotateFunc(void (*func)(int x, int y, int z));

ARGUMENTS
       func	 The new spaceball rotate callback function.

DESCRIPTION
       glutSpaceballRotateFunc	sets  the  Spaceball  rotate callback for the current window. The Spaceball rotate callback for a window is called
       when the window has Spaceball input focus (normally, when the mouse is in the window) and the user generates Spaceball rotations. The x, y,
       and  z  callback parameters indicate the rotation along the X, Y, and Z axes. The callback parameters are normalized to be within the range
       of -1800 to 1800 inclusive.

       Registering a Spaceball rotate callback when a Spaceball device is not available is ineffectual and not an error. In this case,	no  Space-
       ball rotate callbacks will be generated.

       Passing	NULL  to glutSpaceballRotateFunc disables the generation of Spaceball rotate callbacks. When a new window is created, no Spaceball
       rotate callback is initially registered.
