XChangeKeyboardDevice - change which device is used as the X keyboard


   #include <X11/extensions/XInput.h>

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

          Specifies the connection to the X server.

          Specifies the device to be used as the X keyboard.


       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


              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 XChangeKeyboardDevice request
              was made specifying a device that has no keys.
