                KeySym keysym;

          void XConvertCase(keysym, lower_return, upper_return)
                KeySym keysym;

     ARGUMENTS
          display   Specifies the connection to the X server.

          index     Specifies the element of KeyCode vector.

          keycode   Specifies the KeyCode.

          keysym    Specifies the KeySym that is to be searched for or
                    converted.

          lower_return
                    Returns the lowercase form of keysym, or keysym.

          string    Specifies the name of the KeySym that is to be
                    converted.

          upper_return
                    Returns the uppercase form of keysym, or keysym.

     DESCRIPTION
          Standard KeySym names are obtained from <X11/keysymdef.h> by
          removing the XK_ prefix from each name.  KeySyms that are
          not part of the Xlib standard also may be obtained with this
          function.  The set of KeySyms that are available in this
          manner and the mechanisms by which Xlib obtains them is
          implementation-dependent.
          If the KeySym name is not in the Host Portable Character
          Encoding, the result is implementation-dependent.  If the
          specified string does not match a valid KeySym,
          XStringToKeysym returns NoSymbol.

          The returned string is in a static area and must not be
          modified.  The returned string is in the Host Portable
          Character Encoding.  If the specified KeySym is not defined,
          XKeysymToString returns a NULL.

          The XKeycodeToKeysym function uses internal Xlib tables and
          returns the KeySym defined for the specified KeyCode and the
          element of the KeyCode vector.  If no symbol is defined,
          XKeycodeToKeysym returns NoSymbol.

          If the specified KeySym is not defined for any KeyCode,
          XKeysymToKeycode returns zero.

          The XConvertCase function returns the uppercase and
          lowercase forms of the specified Keysym, if the KeySym is
          subject to case conversion; otherwise, the specified KeySym
          is returned to both lower_return and upper_return.  Support
          for conversion of other than Latin and Cyrillic KeySyms is
          implementation-dependent.
