XChangeKeyboardDevice(3) X FUNCTIONS XChangeKeyboardDevice(3)
NAME
XChangeKeyboardDevice - change which device is used as the X keyboard
SYNTAX
Status XChangeKeyboardDevice(Display *display, XDevice *device);
ARGUMENTS
display Specifies the connection to the X server.
device Specifies the device to be used as the X keyboard.
DESCRIPTION
The XChangeKeyboardDevice request causes the server to use the speci-
fied 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 MappingNotify 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 extension protocol requests.
XChangeKeyboardDevice can generate a BadDevice or a BadMatch error.
DIAGNOSTICS
BadDevice An invalid device was specified. The specified device does
not exist, has not been opened by this client via XOpenIn-
putDevice, or is already one of the core X device (pointer
or keyboard). This error may also occur if the server
implementation 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.
