XChangeKeyboardDevice(3)                         X FUNCTIONS                        XChangeKeyboardDevice(3)



NAME
       XChangeKeyboardDevice - change which device is used as the X keyboard

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

ARGUMENTS
       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.
