XkbUpdateMapFromCore(3) 					   XKB FUNCTIONS					   XkbUpdateMapFromCore(3)

NAME

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

SYNOPSIS

       Bool XkbUpdateMapFromCore ( xkb, first_key, num_keys, map_width, core_keysyms, changes )
	     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 descrip-
       tion 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.
