XkbUpdateMapFromCore(3) XKB FUNCTIONS XkbUpdateMapFromCore(3) NAME XkbUpdateMapFromCore - Update a local Xkb keyboard map to reflect the map- ping 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 compatibil- ity map to configure a client-side Xkb keyboard mapping, given a core pro- tocol representation of part or all of a keyboard mapping. Obtain a core protocol representation of a keyboard mapping from an actual server (by us- ing 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 correspond- ing 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 MappingNo- tify 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 en- tries 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, XkbUpdateMapFrom- Core backfills the changes structure whose address is passed in changes to indicate the modifications that were made. You may then use changes in sub- sequent calls such as XkbSetMap, to propagate the local modifications to a server. SEE ALSO XkbSetMap(3) X Version 11 libX11 1.8.13 XkbUpdateMapFromCore(3)
