24 Xkb allows applications to obtain information about indicators using
25 two different methods. The first method, which is similar to the core X
26 implementation, uses a mask to specify the indicators. The second
27 method, which is more suitable for applications concerned with interop‐
28 erability, uses indicator names. The correspondence between the indica‐
29 tor name and the bit position in masks is as follows: one of the param‐
30 eters returned from XkbGetNamedIndicators is an index that is the bit
31 position to use in any function call that requires a mask of indicator
32 bits, as well as the indicator's index into the XkbIndicatorRec array
33 of indicator maps.
34 XkbGetIndicatorState queries the display for the state of the indica‐
36 tors on the device specified by the device_spec. For each indicator
37 that is "turned on" on the device, the associated bit is set in
38 state_return. If a compatible version of the Xkb extension is not
39 available in the server, XkbGetIndicatorState returns a BadMatch error.
40 Otherwise, it sends the request to the X server, places the state of
41 the indicators into state_return, and returns Success. Thus the value
42 reported by XkbGetIndicatorState is identical to the value reported by
43 the core protocol.

46 BadMatch A compatible version of Xkb was not available in the
47 server or an argument has correct type and range, but is
48 otherwise invalid
