DESCRIPTION

45       Xkb also allows applications  to  refer  to  indicators  by  name.  Use
46       XkbGetNames to get the indicator names. Using names eliminates the need
47       for hard-coding bitmask values for particular keyboards.  For  example,
48       instead  of  using vendor-specific constants such as WSKBLed_ScrollLock
49       mask on Digital workstations or XLED_SCROLL_LOCK on  Sun  workstations,
50       you  can  instead use XkbGetNamedDeviceIndicator to look up information
51       on the indicator named "Scroll Lock."
52
53       If the device specified by device_spec has  an  indicator  named  name,
54       XkbGetNamedDeviceIndicator  returns  True and populates the rest of the
55       parameters with information about  the  indicator.  Otherwise,  XkbGet‐
56       NamedDeviceIndicator returns False.
57
58       The ndx_rtrn field returns the zero-based index of the named indicator.
59       This index is the bit  position  to  use  in  any  function  call  that
60       requires  a  mask  of  indicator bits, as well as the indicator's index
61       into the XkbIndicatorRec array of indicator maps.   state_rtrn  returns
62       the  current  state  of  the  named indicator (True = on, False = off).
63       map_rtrn returns the indicator map for the named  indicator.  In  addi‐
64       tion,  if  the  indicator  is  mapped  to a physical LED, the real_rtrn
65       parameter is set to True.
66
67       Each of the " _rtrn " arguments is optional; you can pass NULL for  any
68       unneeded " _rtrn " arguments.

71       XkbGetNamedIndicator  is a convenience function that calls XkbGetNamed‐
72       DeviceIndicator with a device_spec of  XkbUseCoreKbd,  a  led_class  of
73       XkbDfltXIClass,  and  a  led_id  of XkbDfltXIId.  It returns the return
74       value from XkbGetNamedDeviceIndicator.

RETURN VALUES

78       True           The XkbGetNamedIndicator and  XkbGetNamedDeviceIndicator
79                      functions   return  True  if  the  device  specified  by
80                      device_spec has an indicator named name.
81
82       False          The XkbGetNamedIndicator and  XkbGetNamedDeviceIndicator
83                      functions  return  False  if  the  device  specified  by
84                      device_spec does not have an indicator named name.
