XkbGetIndicatorState(3)          XKB FUNCTIONS         XkbGetIndicatorState(3)



NAME
       XkbGetIndicatorState - Obtains the current state of the keyboard
       indicators

SYNOPSIS
       Status XkbGetIndicatorState (Display *display, unsigned int
               device_spec, unsigned int state_return);


ARGUMENTS
       - display
              connection to the X server

       - device_spec
              device ID, or XkbUseCoreKbd

       - state_return
              backfilled with a mask of the indicator state

DESCRIPTION
       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 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.

       XkbGetIndicatorState queries the display for the state of the
       indicators on the device specified by the device_spec. For each
       indicator that is "turned on" on the device, the associated bit is set
       in state_return. If a compatible version of the Xkb extension is not
       available in the server, XkbGetIndicatorState returns a BadMatch error.
       Otherwise, it sends the request to the X server, places the state of
       the indicators into state_return, and returns Success. Thus the value
       reported by XkbGetIndicatorState is identical to the value reported by
       the core protocol.

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