XLookupKeysym(3X11)	XLIB FUNCTIONS	    XLookupKeysym(3X11)

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

SYNTAX
       KeySym XLookupKeysym(key_event, index)
	     XKeyEvent *key_event;
	     int index;

       XRefreshKeyboardMapping(event_map)
	     XMappingEvent *event_map;

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

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

ARGUMENTS
       buffer_return
		 Returns the translated characters.

       bytes_buffer
		 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.

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

       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 .

       keysym_return
		 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 modi-
		 fier list.

       status_in_out
		 Specifies or returns the XComposeStatus struc-
		 ture or NULL.

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

DESCRIPTION
       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 XKey-
       PressedEvent 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 specifica-
       tion.  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 char-
       acter or (if the Control modifier is on) to an ASCII con-
       trol 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 struc-
       tures is implementation-dependent; a portable program must
       pass NULL for this argument.

       The XRebindKeysym function can be used to rebind the mean-
       ing 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.
