glutGetModifiers(3GLUT) 					       GLUT						   glutGetModifiers(3GLUT)

NAME

       glutGetModifiers - returns the modifier key state when certain callbacks were generated.

SYNTAX

       int glutGetModifiers(void);

DESCRIPTION

       glutGetModifiers  returns the modifier key state at the time the input event for a keyboard, special, or mouse callback is generated.  This
       routine may only be called while a keyboard, special, or mouse callback is being handled. The window system is permitted to intercept  win-
       dow  system  defined  modifier  key  strokes or mouse buttons, in which case, no GLUT callback will be generated. This interception will be
       independent of use of glutGetModifiers.

       The bitmask components of the returned integer value are:

       GLUT_ACTIVE_SHIFT
	       Set if the Shift modifier or Caps Lock is active.

       GLUT_ACTIVE_CTRL
	       Set if the Ctrl modifier is active.

       GLUT_ACTIVE_ALT
	       Set if the Alt modifier is active.

NAME

       glutKeyboardFunc - sets the keyboard callback for the current window.

SYNTAX

       #include <GLUT/glut.h>

       void glutKeyboardFunc(void (*func)(unsigned char key,
			     int x, int y));

ARGUMENTS

       func	 The new keyboard callback function.

DESCRIPTION

       glutKeyboardFunc  sets the keyboard callback for the current window.  When a user types into the window, each key press generating an ASCII
       character will generate a keyboard callback. The key callback parameter is the generated ASCII character. The state of modifier	keys  such
       as  Shift cannot be determined directly; their only effect will be on the returned ASCII data. The x and y callback parameters indicate the
       mouse location in window relative coordinates when the key was pressed. When a new window is created, no  keyboard  callback  is  initially
       registered,  and  ASCII	key  strokes in the window are ignored. Passing NULL to glutKeyboardFunc disables the generation of keyboard call-
       backs.

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

       Use glutSpecialFunc for a means to detect non-ASCII key strokes.
