.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"

Success
|
|
The
|
|
.I 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.

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.
