XChangeKeyboardDevice(3X11)XChangeKeyboardDevice(3X11)NAMEXChangeKeyboardDevice - change which device is used as the X keyboard
SYNOPSIS
Status XChangeKeyboardDevice(display, device)
Display *display;
XDevice *device;
ARGUMENTS
Specifies the connection to the X server. 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
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. This error may occur if an XChangeKeyboard‐
Device request was made specifying a device that has no keys.
