XChangeKeyboardDevice - change which device is used as the X
keyboard
Status XChangeKeyboardDevice(Display *display, XDevice *dev-
ice);
display Specifies the connection to the X server.
device Specifies the device to be used as the X key-
board.
The XChangeKeyboardDevice request causes the server to use
the specified device as the X keyboard. The device must
have been previously opened by the requesting client via
XOpenDevice or a BadDevice error will result. The device
must support input class Keys, or a BadMatch error will
result. If the server implementation does not support using
the requested device as the X keyboard, a BadDevice error
will result.
If the specified device is grabbed by another client,
AlreadyGrabbed is returned. If the specified device is
frozen by a grab on another device, GrabFrozen is returned.
If the request is successful, Success is returned.
If the request succeeds, a ChangeDeviceNotify event is sent
to all clients that have selected that event. A MappingNo-
tify event with request = MappingKeyboard is sent to all
clients. The specified device becomes the X keyboard and the
old X keyboard becomes accessible through the input exten-
sion protocol requests.
XChangeKeyboardDevice can generate a BadDevice or a BadMatch
error.
BadDevice An invalid device was specified. The specified
device does not exist, has not been opened by
this client via XOpenInputDevice, or is already
one of the core X device (pointer or keyboard).
This error may also occur if the server imple-
mentation does not support using the specified
device as the X keyboard.
BadMatch This error may occur if an XChangeKeyboardDevice
request was made specifying a device that has no
keys.
