XkbGetNamedIndicator(3)                   XKB FUNCTIONS                   XkbGetNamedIndicator(3)



NAME
       XkbGetNamedIndicator - Look up the indicator map and other information for an indicator by
       name

SYNOPSIS
       Bool  XkbGetNamedDeviceIndicator  (Display  *dpy,  unsigned  int  dev_spec,  unsigned  int
              led_class,  unsigned  int  led_id,  Atom  name,  int  *ndx_rtrn,  Bool *state_rtrn,
              XkbIndicatorMapPtr map_rtrn, Bool *real_rtrn);

       Bool XkbGetNamedIndicator (Display *dpy,  Atom  name,  int  *ndx_rtrn,  Bool  *state_rtrn,
              XkbIndicatorMapPtr map_rtrn, Bool *real_rtrn);

ARGUMENTS
       - dpy  connection to the X server

       - dev_spec
              keyboard device ID, or XkbUseCoreKbd

       - led_class
              feedback class, or XkbDfltXIClass

       - led_id
              feedback ID, or XkbDfltXIId

       - name name of the indicator to be retrieved

       - ndx_rtrn
              backfilled with the index of the retrieved indicator

       - state_rtrn
              backfilled with the current state of the retrieved indicator

       - map_rtrn
               backfilled with the mapping for the retrieved indicator

       - real_rtrn
              backfilled with True if the named indicator is real (physical)

DESCRIPTION
       Xkb  also  allows  applications to refer to indicators by name. Use XkbGetNames to get the
       indicator names. Using names eliminates the need for hard-coding bitmask values  for  par-
       ticular  keyboards.  For  example,  instead  of  using  vendor-specific  constants such as
       WSKBLed_ScrollLock mask on Digital workstations or XLED_SCROLL_LOCK on  Sun  workstations,
       you  can  instead  use  XkbGetNamedDeviceIndicator to look up information on the indicator
       named "Scroll Lock."

       If the device specified by device_spec has an indicator named name, XkbGetNamedDeviceIndi-
       cator  returns  True  and  populates the rest of the parameters with information about the
       indicator. Otherwise, XkbGetNamedDeviceIndicator returns False.

       The ndx_rtrn field returns the zero-based index of the named indicator. This index 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.   state_rtrn
       returns  the  current  state  of  the  named indicator (True = on, False = off).  map_rtrn
       returns the indicator map for the named indicator. In addition, if the indicator is mapped
       to a physical LED, the real_rtrn parameter is set to True.

       Each  of the " _rtrn " arguments is optional; you can pass NULL for any unneeded " _rtrn "
       arguments.


       XkbGetNamedIndicator is a convenience function that calls XkbGetNamedDeviceIndicator  with
       a  device_spec  of  XkbUseCoreKbd,  a  led_class  of XkbDfltXIClass, and a led_id of XkbD-
       fltXIId.  It returns the return value from XkbGetNamedDeviceIndicator.


RETURN VALUES
       True           The XkbGetNamedIndicator and  XkbGetNamedDeviceIndicator  functions  return
                      True if the device specified by device_spec has an indicator named name.

       False          The  XkbGetNamedIndicator  and  XkbGetNamedDeviceIndicator functions return
                      False if the device specified by device_spec does  not  have  an  indicator
                      named name.
