NAME

       glutIgnoreKeyRepeat - determines if auto repeat keystrokes are reported to the current window

SYNTAX

       #include <GLUT/glut.h>

       void glutIgnoreKeyRepeat(int ignore);

ARGUMENTS

       ignore	 Non-zero  indicates auto repeat keystrokes should not be reported by the keyboard and special callbacks; zero indicates that auto
		 repeat keystrokes will be reported.

DESCRIPTION

       glutIgnoreKeyRepeat determines if auto repeat keystrokes are reported to the current window.  The ignore auto repeat state of a window  can
       be queried with glutDeviceGet(GLUT_DEVICE_IGNORE_KEY_REPEAT).

       Ignoring  auto  repeated  keystrokes  is generally done in conjunction with using the glutKeyboardUpFunc and glutSpecialUpFunc callbacks to
       repeat key releases.  If you do not ignore auto repeated keystrokes, your GLUT application will	experience  repeated  release/press  call-
       backs.  Games using the keyboard will typically want to ignore key repeat.

GLUT IMPLEMENTATION NOTES FOR X11
       X11  sends  KeyPress  events repeatedly when the window system's global auto repeat is enabled.	glutIgnoreKeyRepeat can prevent these auto
       repeated keystrokes from being reported as keyboard or special callbacks, but there is still some minimal overhead by the X server to  con-
       tinually  stream  KeyPress events to the GLUT application.  The glutSetKeyRepeat routine can be used to actually disable the global sending
       of auto repeated KeyPress events.  Note that glutSetKeyRepeat affects the global window system auto repeat state so other applications will
       not auto repeat if you disable auto repeat globally through glutSetKeyRepeat.

NAME

       glutKeyboardUpFunc - sets the keyboard up (key release) callback for the current window.

SYNTAX

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

ARGUMENTS

       func	 The new keyboard up callback function.

DESCRIPTION

       glutKeyboardFunc  sets  the keyboard up (key release) callback for the current window.  When a user types into the window, each key release
       matching an ASCII character will generate a keyboard up 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 callbacks.

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

       To avoid the reporting of key release/press pairs due to auto repeat, use glutIgnoreKeyRepeat to ignore auto repeated keystrokes.

       There  is no guarantee that the keyboard press callback will match the exact ASCII character as the keyboard up callback.  For example, the
       key down may be for a lowercase b, but the key release may report an uppercase B if the shift state has changed.  The same applies to  sym-
       bols and control characters.  The precise behavior is window system dependent.

       Use glutSpecialUpFunc for a means to detect non-ASCII key releases.
