XkbGetUpdatedMap(3) XKB FUNCTIONS XkbGetUpdatedMap(3)
NAME
XkbGetUpdatedMap - Update the client or server map information in an existing keyboard
description
SYNOPSIS
Status XkbGetUpdatedMap ( display, which, xkb )
Display * display;
unsigned int which;
XkbDescPtr 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 com-
ponents of the xkb structure are not already allocated, XkbGetUpdatedMap allocates them.
XkbGetUpdatedMap fetches the requested information for the device specified in the XkbDe-
scRec 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 unsuc-
cessful, 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).
RETURN VALUES
Success The XkbGetUpdatedMap function returns Success if a reply is received to the
server query for the desired information.
STRUCTURES
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.

DIAGNOSTICS
BadAlloc Unable to allocate storage
