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

.TE
.I XkbGetUpdatedMap
is synchronous; it queries the server for the desired information, waits for a
reply, and then returns. If successful,
.I XkbGetUpdatedMap
returns Success. If unsuccessful,
.I XkbGetUpdatedMap
returns one of the following: BadAlloc (unable to allocate a component in the
XkbDescRec structure), BadValue (some mask bits in
.I 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).
.SH "RETURN VALUES"
.TP 15
Success
The
.I XkbGetUpdatedMap
function returns Success if a reply is received to the server query for the desired information.
.SH STRUCTURES
.LP
The complete description of an Xkb keyboard is given by an XkbDescRec. The
component
structures in the XkbDescRec represent the major Xkb components.
.nf
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;
.fi
The
.I display
field points to an X display structure. The
.I flags
field is private to the library: modifying
.I flags
may yield unpredictable results. The
.I device_spec
field specifies the device identifier of the keyboard input device, or
XkbUseCoreKeyboard, which specifies the core keyboard device. The
.I min_key_code
and
.I 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.
