XCHANGEKEYBOARDDEVICE(libmansuffix)
===================================

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.
