KeyCode keycode;
Modifiers modifiers;
Modifiers *modifiers_return;
KeySym *keysym_return;
void XtRegisterCaseConverter(display, proc, start, stop)
Display *display;

KeySym start;
KeySym stop;
void XtConvertCase(display, keysym, lower_return,
upper_return)
Display *display;
KeySym keysym;
KeySym *lower_return;
KeySym *upper_return;
ARGUMENTS
display Specifies the display.
keycode Specifies the KeyCode to translate.
keysym Specifies the KeySym to convert.
keysym_return
Returns the resulting KeySym.
lower_return
Returns the lowercase equivalent of the KeySym.
upper_return
Returns the uppercase equivalent of the KeySym.
modifiers Specifies the modifiers to the KeyCode.
modifiers_return
Returns a mask that indicates the modifiers
actually used to generate the KeySym.
proc Specifies the procedure that is to perform key
translations or conversions.
start Specifies the first KeySym for which this
converter is valid.
stop Specifies the last KeySym for which this converter
is valid.
DESCRIPTION
The XtSetKeyTranslator function sets the specified procedure
as the current key translator. The default translator is
XtTranslateKey, an XtKeyProc that uses Shift and Lock
modifiers with the interpretations defined by the core
protocol. It is provided so that new translators can call
it to get default KeyCode-to-KeySym translations and so that
the default translator can be reinstalled.
The XtTranslateKeycode function passes the specified
arguments directly to the currently registered KeyCode to
KeySym translator.
The XtRegisterCaseConverter registers the specified case
converter. The start and stop arguments provide the
inclusive range of KeySyms for which this converter is to be
called. The new converter overrides any previous converters
for KeySyms in that range. No interface exists to remove
converters; you need to register an identity converter.
When a new converter is registered, the Intrinsics
refreshes the keyboard state if necessary. The default
converter understands case conversion for all KeySyms
defined in the core protocol.
The XtConvertCase function calls the appropriate converter
and returns the results. A user-supplied XtKeyProc may need
to use this function.
