14 display
15 Specifies the connection to the X server.
16
17 device
18 Specifies the device to be used as the X keyboard.

21 The XChangeKeyboardDevice request causes the server to use the
22 specified device as the X keyboard. The device must have been
23 previously opened by the requesting client via XOpenDevice or a
24 BadDevice error will result. The device must support input
25 class Keys, or a BadMatch error will result. If the server
26 implementation does not support using the requested device as
27 the X keyboard, a BadDevice error will result.
28
29 If the specified device is grabbed by another client,
30 AlreadyGrabbed is returned. If the specified device is frozen
31 by a grab on another device, GrabFrozen is returned. If the
32 request is successful, Success is returned.
33
34 If the request succeeds, a ChangeDeviceNotify event is sent to
35 all clients that have selected that event. A MappingNotify
36 event with request = MappingKeyboard is sent to all clients.
37 The specified device becomes the X keyboard and the old X
38 keyboard becomes accessible through the input extension
39 protocol requests.
40
41 XChangeKeyboardDevice can generate a BadDevice or a BadMatch
42 error.
43
45 BadDevice
46 An invalid device was specified. The specified device
47 does not exist, has not been opened by this client via
48 XOpenInputDevice, or is already one of the core X device
49 (pointer or keyboard). This error may also occur if the
50 server implementation does not support using the
51 specified device as the X keyboard.
52
53 BadMatch
54 This error may occur if an XChangeKeyboardDevice request
55 was made specifying a device that has no keys.
