       XLookupKeysym,  XRefreshKeyboardMapping,  XLookupString,  XRebindKeysym  - handle keyboard
       input events in Latin-1


       KeySym XLookupKeysym(XKeyEvent *key_event, int index);

       int XRefreshKeyboardMapping(XMappingEvent *event_map);

       int XLookupString(XKeyEvent *event_struct, char *buffer_return, int  bytes_buffer,  KeySym
              *keysym_return, XComposeStatus *status_in_out);

       int  XRebindKeysym(Display *display, KeySym keysym, KeySym list[], int mod_count, unsigned
              char *string, int num_bytes);


                 Returns the translated characters.

                 Specifies the length of the buffer.  No more than  bytes_buffer  of  translation
                 are returned.

       num_bytes Specifies the number of bytes in the string argument.

       display   Specifies the connection to the X server.

       event_map Specifies the mapping event that is to be used.

                 Specifies  the key event structure to be used.  You can pass XKeyPressedEvent or

       index     Specifies the index into the KeySyms list for the event's KeyCode.

       key_event Specifies the KeyPress or KeyRelease event.

       keysym    Specifies the KeySym that is to be returned.

                 Returns the KeySym computed from the event if this argument is not NULL.

       list      Specifies the KeySyms to be used as modifiers.

       mod_count Specifies the number of modifiers in the modifier list.

                 Specifies or returns the XComposeStatus structure or NULL.

       string    Specifies the string that is copied and will be returned by XLookupString.


       The XLookupKeysym function uses a given keyboard event and  the  index  you  specified  to
       return  the  KeySym  from  the  list  that  corresponds  to  the  KeyCode  member  in  the
       XKeyPressedEvent or XKeyReleasedEvent structure.  If no KeySym is defined for the  KeyCode
       of the event, XLookupKeysym returns NoSymbol.

       The XRefreshKeyboardMapping function refreshes the stored modifier and keymap information.
       You usually call this function when  a  MappingNotify  event  with  a  request  member  of
       MappingKeyboard  or  MappingModifier  occurs.  The result is to update Xlib's knowledge of
       the keyboard.

       The XLookupString function translates a key event to a KeySym and a string.  The KeySym is
       obtained  by  using  the  standard  interpretation  of the Shift, Lock, group, and numlock
       modifiers as defined in the X Protocol specification.  If the KeySym has been rebound (see
       XRebindKeysym),  the  bound string will be stored in the buffer.  Otherwise, the KeySym is
       mapped, if possible, to an ISO Latin-1 character or (if the Control modifier is on) to  an
       ASCII  control  character,  and  that  character  is  stored in the buffer.  XLookupString
       returns the number of characters that are stored in the buffer.

       If present (non-NULL), the XComposeStatus structure records the state, which is private to
       Xlib,  that  needs  preservation  across  calls  to  XLookupString  to  implement  compose
       processing.  The creation of  XComposeStatus  structures  is  implementation-dependent;  a
       portable program must pass NULL for this argument.

       The  XRebindKeysym  function can be used to rebind the meaning of a KeySym for the client.
       It does not redefine any key in the X server but merely provides  an  easy  way  for  long
       strings  to  be  attached to keys.  XLookupString returns this string when the appropriate
       set of modifier keys are pressed and  when  the  KeySym  would  have  been  used  for  the
       translation.   No  text conversions are performed; the client is responsible for supplying
       appropriately encoded strings.  Note that you can rebind a KeySym that may not exist.
