NAME

       XChangeKeyboardDevice - change which device is used as the X keyboard

SYNOPSIS

       #include <X11/extensions/XInput.h>

       Status XChangeKeyboardDevice( Display *display,
                                     XDevice *device);

       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.
