6 XkbGetUpdatedMap - Update the client or server map information in an
7 existing keyboard description
8
10 Status XkbGetUpdatedMap (Display *display, unsigned int which, XkbDe‐
11 scPtr xkb);
12
14 - display
15 connection to X server
16 - which
18 mask selecting subcomponents to populate
19 - xkb keyboard description to be updated
21
23 The which parameter is a bitwise inclusive OR of the masks in Table 1.
24 If the needed components of the xkb structure are not already allo‐
25 cated, XkbGetUpdatedMap allocates them. XkbGetUpdatedMap fetches the
26 requested information for the device specified in the XkbDescRec passed
27 in the xkb parameter.

53 XkbGetUpdatedMap is synchronous; it queries the server for the desired
55 information, waits for a reply, and then returns. If successful, XkbGe‐
56 tUpdatedMap returns Success. If unsuccessful, XkbGetUpdatedMap returns
57 one of the following: BadAlloc (unable to allocate a component in the
58 XkbDescRec structure), BadValue (some mask bits in which are unde‐
59 fined), BadImplementation (a compatible version of the Xkb extension is
60 not available in the server or the reply from the server was invalid).
61
63 Success The XkbGetUpdatedMap function returns Success if a reply
64 is received to the server query for the desired informa‐
65 tion.
66
68 The complete description of an Xkb keyboard is given by an XkbDescRec.
69 The component structures in the XkbDescRec represent the major Xkb com‐
70 ponents.
71 typedef struct {
73 struct _XDisplay * display; /∗ connection to X server */
74 unsigned short flags; /∗ private to Xkb, do not modify */
75 unsigned short device_spec; /∗ device of interest */
76 KeyCode min_key_code; /∗ minimum keycode for device */
77 KeyCode max_key_code; /∗ maximum keycode for device */
78 XkbControlsPtr ctrls; /∗ controls */
79 XkbServerMapPtr server; /∗ server keymap */
80 XkbClientMapPtr map; /∗ client keymap */
81 XkbIndicatorPtr indicators; /∗ indicator map */
82 XkbNamesPtr names; /∗ names for all components */
83 XkbCompatMapPtr compat; /∗ compatibility map */
84 XkbGeometryPtr geom; /∗ physical geometry of keyboard */
85 } XkbDescRec, *XkbDescPtr;
86 The display field points to an X display structure. The flags field is
88 private to the library: modifying flags may yield unpredictable re‐
89 sults. The device_spec field specifies the device identifier of the
90 keyboard input device, or XkbUseCoreKeyboard, which specifies the core
91 keyboard device. The min_key_code and max_key_code fields specify the
92 least and greatest keycode that can be returned by the keyboard.
93 Each structure component has a corresponding mask bit that is used in
95 function calls to indicate that the structure should be manipulated in
96 some manner, such as allocating it or freeing it. These masks and their
97 relationships to the fields in the XkbDescRec are shown in Table 2.
