NAME

     XChangeKeyboardDevice - change which device is used as the X
     keyboard

SYNTAX

     Status XChangeKeyboardDevice(Display *display, XDevice *dev-
          ice);

ARGUMENTS

     display     Specifies the connection to the X server.

     device      Specifies the device to be used as the X key-
                 board.

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 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.

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 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.
