XkbGetDeviceLedInfo(3)           XKB FUNCTIONS          XkbGetDeviceLedInfo(3)

       XkbGetDeviceLedInfo  - Query the indicator names, maps, and state asso-
       ciated with an LED feedback of an input extension device

       Status XkbGetDeviceLedInfo (Display *dpy, XkbDeviceInfoPtr device_info,
              unsigned  int  led_class,  unsigned  int  led_id,  unsigned  int

       - dpy  connection to X server

       - device_info
              structure to update with results

       - led_class
              LED feedback class assigned by input extension

       - led_id
              LED feedback ID assigned by input extension

       - which
              mask indicating desired information

       XkbGetDeviceLedInfo queries the server for the desired LED  information
       for  the  feedback  specified  by  led_class and led_id for the X input
       extension device indicated by device_spec->device_info and waits for  a
       reply. If successful, XkbGetDeviceLedInfo backfills the relevant fields
       of device_info as determined by which with the results and returns Suc-
       cess. Valid values for which are the inclusive OR of any of XkbXI_Indi-
       catorNamesMask, XkbXI_IndicatorMapsMask, and XkbXI_IndicatorStateMask.

       The fields of device_info that are filled in when this request succeeds
       are  name,  type,  supported, and unsupported, and portions of the leds
       structure corresponding to led_class and led_id  as  indicated  by  the
       bits set in which.  The device_info->leds vector is allocated if neces-
       sary and sz_leds and num_leds filled  in.  The  led_class,  led_id  and
       phys_indicators  fields of the device_info->leds entry corresponding to
       led_class and led_id are always filled in.

       If which contains XkbXI_IndicatorNamesMask, the names_present and names
       fields  of  the  device_info->leds structure corresponding to led_class
       and led_id are updated, if which contains XkbXI_IndicatorStateMask, the
       corresponding state field is updated, and if which contains XkbXI_Indi-
       catorMapsMask, the maps_present and maps fields are updated.

       If a compatible version of Xkb is not available in the  server  or  the
       Xkb  extension  has  not been properly initialized, XkbGetDeviceLedInfo
       returns BadAccess. If allocation errors occur,  a  BadAlloc  status  is
       returned.  If  the  device  has  no  indicators,  a  BadMatch  error is
       returned. If ledClass or ledID have illegal values, a BadValue error is
       returned.  If they have legal values but do not specify a feedback that
       contains LEDs and is associated with the specified device,  a  BadMatch
       error is returned.

       BadAccess      The Xkb extension has not been properly initialized

       BadAlloc       Unable to allocate storage

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

       BadValue       An argument is out of range
