       XkbGetUpdatedMap  -   Update  the client or server map information in an existing keyboard


       Status XkbGetUpdatedMap (Display *display, unsigned int which, XkbDescPtr xkb);


       - display
              connection to X server

       - which
              mask selecting subcomponents to populate

       - xkb  keyboard description to be updated


       The which parameter is a bitwise inclusive OR of the masks  in  Table  1.  If  the  needed
       components  of  the  xkb  structure  are not already allocated, XkbGetUpdatedMap allocates
       them.  XkbGetUpdatedMap fetches the requested information for the device specified in  the
       XkbDescRec passed in the xkb parameter.

       XkbGetUpdatedMap is synchronous; it queries the server for the desired information,  waits
       for  a  reply,  and  then  returns.  If  successful,  XkbGetUpdatedMap returns Success. If
       unsuccessful, XkbGetUpdatedMap returns one of the following: BadAlloc (unable to  allocate
       a  component  in  the  XkbDescRec  structure),  BadValue  (some  mask  bits  in  which are
       undefined), BadImplementation (a compatible version of the Xkb extension is not  available
       in the server or the reply from the server was invalid).


       Success        The XkbGetUpdatedMap function returns Success if a reply is received to the
                      server query for the desired information.


       The complete description of an Xkb keyboard is  given  by  an  XkbDescRec.  The  component
       structures in the XkbDescRec represent the major Xkb components.

       typedef struct {
          struct _XDisplay * display;      /∗ connection to X server */
          unsigned short     flags;        /∗ private to Xkb, do not modify */
          unsigned short     device_spec;  /∗ device of interest */
          KeyCode            min_key_code; /∗ minimum keycode for device */
          KeyCode            max_key_code; /∗ maximum keycode for device */
          XkbControlsPtr     ctrls;        /∗ controls */
          XkbServerMapPtr    server;       /∗ server keymap */
          XkbClientMapPtr    map;          /∗ client keymap */
          XkbIndicatorPtr    indicators;   /∗ indicator map */
          XkbNamesPtr        names;        /∗ names for all components */
          XkbCompatMapPtr    compat;       /∗ compatibility map */
          XkbGeometryPtr     geom;         /∗ physical geometry of keyboard */
       } XkbDescRec, *XkbDescPtr;

       The  display  field  points  to  an X display structure. The flags field is private to the
       library: modifying flags may yield unpredictable results. The device_spec field  specifies
       the device identifier of the keyboard input device, or XkbUseCoreKeyboard, which specifies
       the core keyboard device. The min_key_code and max_key_code fields specify the  least  and
       greatest keycode that can be returned by the keyboard.

       Each  structure  component  has a corresponding mask bit that is used in function calls to
       indicate that the structure should be manipulated in some manner, such as allocating it or
       freeing  it. These masks and their relationships to the fields in the XkbDescRec are shown
       in Table 2.
