NAME
glutSpecialFunc -- Sets the Special callback for the current window
LIBRARY
OpenGLUT - input
SYNOPSIS
#include <openglut.h>
void
glutSpecialFunc(void( *callback )( int key, int x, int y ));
PARAMETERS
callback Client function for keyboard event.
DESCRIPTION
Registers a callback for OpenGLUT to call when the user presses "special" keys on the keyboard.
The special callback handles some additional keys that are not covered under plain "keyboard" events. The key that is passed to the call-
back is one of an enumerated set. The association to keys on your keyboard should be obvious. Their GLUT symbol names are:
- GLUT_KEY_F1
- GLUT_KEY_F2
- GLUT_KEY_F3
- GLUT_KEY_F4
- GLUT_KEY_F5
- GLUT_KEY_F6
- GLUT_KEY_F7
- GLUT_KEY_F8
- GLUT_KEY_F9
- GLUT_KEY_F10
- GLUT_KEY_F11
- GLUT_KEY_F12
- GLUT_KEY_LEFT
- GLUT_KEY_UP
- GLUT_KEY_RIGHT
- GLUT_KEY_DOWN
- GLUT_KEY_PAGE_UP
- GLUT_KEY_PAGE_DOWN
- GLUT_KEY_HOME
- GLUT_KEY_END
- GLUT_KEY_INSERT
To receive other keys, see glutKeyboardFunc().
This callback is bound to the current window .
CAVEATS
Many keys are not included; nor is it possible to apply qualifiers such as the Shift or Ctrl key to these keys.
Windows created via glutCreateMenuWindow() always cascade keyboard and mouse events to their parent.

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 window. The special keyboard callback is triggered when keyboard func-
tion 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 call-
back 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.
