NAME
XChangeKeyboardDevice - change which device is used as the X
keyboard
SYNTAX
Status XChangeKeyboardDevice(display, device)
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 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
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 XOpenInputDevice, 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.
