|
|
.SH DESCRIPTION
|
|
.LP
|
|
Xkb allows applications to obtain information about indicators using two
|
|
different methods. The first method, which is similar to the core X
|
|
implementation, uses a mask to specify the indicators. The second method, which
|
|
is more suitable for applications concerned with interoperability, uses
|
|
indicator names. The correspondence between the indicator name and the bit
|
|
position in masks is as follows: one of the parameters returned from
|
|
.I XkbGetNamedIndicators
|
|
is an index that is the bit position to use in any function call that requires a
|
|
mask of indicator bits, as well as the indicator's index into the
|
|
XkbIndicatorRec array of indicator maps.
|
|
|
|
.I XkbGetIndicatorState
|
|
queries the
|
|
.I display
|
|
for the state of the indicators on the device specified by the
|
|
.I device_spec.
|
|
For each indicator that is "turned on" on the device, the associated bit is set
|
|
in
|
|
.I state_return.
|
|
If a compatible version of the Xkb extension is not available in the server,
|
|
.I XkbGetIndicatorState
|
|
returns a BadMatch error. Otherwise, it sends the request to the X server,
|
|
places the state of the indicators into
|
|
.I state_return,
|
|
and returns Success. Thus the value reported by
|
|
.I XkbGetIndicatorState
|
|
is identical to the value reported by the core protocol.
|
|
.SH DIAGNOSTICS
|
|
.TP 15
|
|
.B BadMatch
|
|
A compatible version of Xkb was not available in the server or an argument has
|
|
correct type and range, but is otherwise invalid
