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 XOpen-
       Device  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.
