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 interop-
       erability,  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  avail-
       able 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
