NAME

     glutTimerFunc -- Sets the Timer callback for the current window.

LIBRARY

     OpenGLUT - idletimer

SYNOPSIS

     #include <openglut.h>

     void
     glutTimerFunc(unsigned int msec, void( *callback )( int data ), int data);

PARAMETERS

      msec	   Milliseconds till invocation.

      callback	   Client function for timer event.

      data	   Arbitrary data; passed to  callback	.

DESCRIPTION

     After  at least   msec  milliseconds, OpenGLUT will call  callback  , passing in your user-supplied  data	parameter.  OpenGLUT will call
     your function only once.

     This callback is  not   bound to any window.

CAVEATS

     Unlike most other callbacks, timers only occur once.

     Unlike most other callbacks, you cannot deregister a timer callback.

     Unlike most other callbacks, you can register an arbitrary number of timers.

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.
