XtKeyProc()															       XtKeyProc()

Name
  XtKeyProc - interface definition for keycode-to-keysym translation procedure.

Synopsis
  typedef void (*XtKeyProc)(Display *, KeyCode, Modifiers, Modifiers *,
      KeySym *);
	 Display *display;
	 KeyCode keycode;
	 Modifiers modifiers;
	 Modifiers *modifiers_return;
	 KeySym *keysym_return;

Inputs
  display   Specifies the display that the keycode is from.

  keycode   Specifies the keycode that is to be translated.

  modifiers Specifies the mask that indicates what modifier keys (Shift, Meta, Control, etc.) are pressed.

Outputs
  modifiers_return
	    Returns a mask that specifies the modifier keys that the function examined in making the conversion.

  keysym_return
	    Returns the resulting keysym.

Description
  An  XtKeyProc is registered in a call to XtSetKeyTranslator() and is invoked explicitly by a call to XtTranslateKeycode() and automatically
  by the Translation Manager in order to convert incoming keycodes to keysyms.

  An XtKeyProc must convert the keycode and modifiers into a keysym and return that keysym in keysym_return.  It should return the  modifiers
  that it considers in its translation in modifiers_return.  The value returned in this argument will be a constant for any given XtKeyProc.

  An XtKeyProc must be implemented so that multiple calls with the same display, keycode, and modifiers arguments will return the same result
  until either a new case converter (an XtCaseProc) is registered or a MappingNotify event is received.

Usage
  XtTranslateKey() is the default XtKeyProc.  It should be sufficient for all applications except those that use non-standard keysyms.

  When writing an XtKeyProc, you will probably need to call XtConvertCase(), and XtGetKeysymTable().  You may also want  to  invoke  XtTrans-
  lateKey() directly to translate the standard keysyms.
