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 cur-
       rent  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 Spaceball
       rotate callbacks will be generated.

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