6 XkbGetDeviceLedInfo - Query the indicator names, maps, and state asso‐
7 ciated with an LED feedback of an input extension device
8
10 Status XkbGetDeviceLedInfo (Display *dpy, XkbDeviceInfoPtr device_info,
11 unsigned int led_class, unsigned int led_id, unsigned int
12 which);
13
15 - dpy connection to X server
16 - device_info
18 structure to update with results
19 - led_class
21 LED feedback class assigned by input extension
22 - led_id
24 LED feedback ID assigned by input extension
25 - which
27 mask indicating desired information
28
30 XkbGetDeviceLedInfo queries the server for the desired LED information
31 for the feedback specified by led_class and led_id for the X input
32 extension device indicated by device_spec->device_info and waits for a
33 reply. If successful, XkbGetDeviceLedInfo backfills the relevant fields
34 of device_info as determined by which with the results and returns Suc‐
35 cess. Valid values for which are the inclusive OR of any of XkbXI_Indi‐
36 catorNamesMask, XkbXI_IndicatorMapsMask, and XkbXI_IndicatorStateMask.
37 The fields of device_info that are filled in when this request succeeds
39 are name, type, supported, and unsupported, and portions of the leds
40 structure corresponding to led_class and led_id as indicated by the
41 bits set in which. The device_info->leds vector is allocated if neces‐
42 sary and sz_leds and num_leds filled in. The led_class, led_id and
43 phys_indicators fields of the device_info->leds entry corresponding to
44 led_class and led_id are always filled in.
45 If which contains XkbXI_IndicatorNamesMask, the names_present and names
47 fields of the device_info->leds structure corresponding to led_class
48 and led_id are updated, if which contains XkbXI_IndicatorStateMask, the
49 corresponding state field is updated, and if which contains XkbXI_Indi‐
50 catorMapsMask, the maps_present and maps fields are updated.
51 If a compatible version of Xkb is not available in the server or the
53 Xkb extension has not been properly initialized, XkbGetDeviceLedInfo
54 returns BadAccess. If allocation errors occur, a BadAlloc status is
55 returned. If the device has no indicators, a BadMatch error is
56 returned. If ledClass or ledID have illegal values, a BadValue error is
57 returned. If they have legal values but do not specify a feedback that
58 contains LEDs and is associated with the specified device, a BadMatch
59 error is returned.

62 BadAccess The Xkb extension has not been properly initialized
63 BadAlloc Unable to allocate storage
65 BadMatch A compatible version of Xkb was not available in the
67 server or an argument has correct type and range, but is
68 otherwise invalid
69 BadValue An argument is out of range
