glutSpecialFunc(3GLUT)		     GLUT		glutSpecialFunc(3GLUT)

NAME
       glutSpecialFunc	-  sets	 the special keyboard callback for the current
       window.

SYNTAX
       void glutSpecialFunc(void (*func)(int key, int x, int y));

ARGUMENTS
       func	 The new special callback function.

DESCRIPTION
       glutSpecialFunc sets the special keyboard callback for the current win‐
       dow.  The special keyboard callback is triggered when keyboard function
       or directional keys are	pressed.  The  key  callback  parameter	 is  a
       GLUT_KEY_*  constant  for the special key pressed. The x and y callback
       parameters indicate the mouse in window relative coordinates  when  the
       key  was	 pressed. When a new window is created, no special callback is
       initially registered and special key strokes in the window are ignored.
       Passing	NULL  to  glutSpecialFunc  disables  the generation of special
       callbacks.

       During a special callback, glutGetModifiers may be called to  determine
       the  state  of modifier keys when the keystroke generating the callback
       occurred.

       An implementation should do its best to provide ways  to	 generate  all
       the GLUT_KEY_* special keys. The available GLUT_KEY_* values are:

       GLUT_KEY_F1
	       F1 function key.

       GLUT_KEY_F2
	       F2 function key.

       GLUT_KEY_F3
	       F3 function key.

       GLUT_KEY_F4
	       F4 function key.

       GLUT_KEY_F5
	       F5 function key.

       GLUT_KEY_F6
	       F6 function key.

       GLUT_KEY_F7
	       F7 function key.

       GLUT_KEY_F8
	       F8 function key.

       GLUT_KEY_F9
	       F9 function key.

       GLUT_KEY_F10
	       F10 function key.

       GLUT_KEY_F11
	       F11 function key.

       GLUT_KEY_F12
	       F12 function key.

       GLUT_KEY_LEFT
	       Left directional key.

       GLUT_KEY_UP
	       Up directional key.

       GLUT_KEY_RIGHT
	       Right directional key.

       GLUT_KEY_DOWN
	       Down directional key.

       GLUT_KEY_PAGE_UP
	       Page up directional key.

       GLUT_KEY_PAGE_DOWN
	       Page down directional key.

       GLUT_KEY_HOME
	       Home directional key.

       GLUT_KEY_END
	       End directional key.

       GLUT_KEY_INSERT
	       Inset directional key.

       Note  that  the	escape, backspace, and delete keys are generated as an
       ASCII character.
