XkbGetUpdatedMap(3)		 XKB FUNCTIONS		   XkbGetUpdatedMap(3)

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

SYNOPSIS
       Status XkbGetUpdatedMap (Display *display, unsigned int	which,	XkbDe‐
	      scPtr xkb);

ARGUMENTS
       - display
	      connection to X server

       - which
	      mask selecting subcomponents to populate

       - xkb  keyboard description to be updated

DESCRIPTION
       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	 allo‐
       cated,  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, XkbGe‐
       tUpdatedMap 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	 unde‐
       fined), BadImplementation (a compatible version of the Xkb extension is
       not available in the server or the reply from the server was invalid).

RETURN VALUES
       Success	      The XkbGetUpdatedMap function returns Success if a reply
		      is received to the server query for the desired informa‐
		      tion.

STRUCTURES
       The complete description of an Xkb keyboard is given by an  XkbDescRec.
       The component structures in the XkbDescRec represent the major Xkb com‐
       ponents.

       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.

	       Table 2 Mask Bits for XkbDescRec
       ──────────────────────────────────────────────────
       Mask Bit		      XkbDescRec Field	 Value
       ──────────────────────────────────────────────────
       XkbControlsMask	      ctrls		 (1L<<0)
       XkbServerMapMask	      server		 (1L<<1)
       XkbIClientMapMask      map		 (1L<<2)
       XkbIndicatorMapMask    indicators	 (1L<<3)
       XkbNamesMask	      names		 (1L<<4)
       XkbCompatMapMask	      compat		 (1L<<5)
       XkbGeometryMask	      geom		 (1L<<6)
       XkbAllComponentsMask   All Fields	 (0x7f)

DIAGNOSTICS
       BadAlloc	      Unable to allocate storage

       BadImplementation
		      Invalid reply from server

       BadValue	      An argument is out of range
