NAME

       XkbUpdateMapFromCore -  Update a local Xkb keyboard map to reflect the mapping expressed by a core format
       mapping

SYNOPSIS

       Bool  XkbUpdateMapFromCore  (XkbDescPtr  xkb,  KeyCode  first_key,  int  num_keys,  int map_width, KeySym
              *core_keysyms, XkbChangesPtr changes);

ARGUMENTS

       xkb    keyboard description to update

       first_key
              keycode of first key description to update

       num_keys
              number of key descriptions to update

       map_width
              width of core protocol keymap

       core_keysyms
              symbols in core protocol keymap

       changes
              backfilled with changes made to Xkb

DESCRIPTION

       Xkb provides several functions that make it easier to apply the compatibility map to configure a  client-
       side  Xkb  keyboard  mapping,  given a core protocol representation of part or all of a keyboard mapping.
       Obtain  a  core  protocol  representation  of  a  keyboard  mapping  from  an  actual  server  (by  using
       XGetKeyboardMapping, for example), a data file, or some other source.

       XkbUpdateMapFromCore  interprets input argument information representing a keyboard map in core format to
       update the Xkb keyboard description passed in xkb.  Only a portion of  the  Xkb  map  is  updated  -  the
       portion  corresponding to keys with keycodes in the range first_key through first_key + num_keys - 1.  If
       XkbUpdateMapFromCore is being called in response to a MappingNotify event,  first_key  and  num_keys  are
       reported  in  the  MappingNotify  event.   core_keysyms contains the keysyms corresponding to the keycode
       range being updated, in core keyboard description order.  map_width is the number of keysyms per  key  in
       core_keysyms.   Thus, the first map_width entries in core_keysyms are for the key with keycode first_key,
       the next map_width entries are for key first_key + 1, and so on.

       In addition to modifying the Xkb keyboard mapping in  xkb,  XkbUpdateMapFromCore  backfills  the  changes
       structure  whose  address is passed in changes to indicate the modifications that were made. You may then
       use changes in subsequent calls such as XkbSetMap, to propagate the local modifications to a server.
