XCHANGEPOINTERDEVICE(3)				       XCHANGEPOINTERDEVICE(3)

NAME
       XChangePointerDevice - change which device is the X pointer

SYNOPSIS
       #include	<X11/extensions/XInput.h>

       Status XChangePointerDevice( Display *display,
				    XDevice *device,
				    int	xaxis,
				    int	yaxis);

       display
	      Specifies	the connection to the X	server.

       device
	      Specifies	the device to be used as the X pointer.

       xaxis
	      Specifies	the axis of the	device to be used as the X
	      pointer x-axis.

       yaxis
	      Specifies	the axis of the	device to be used as the X
	      pointer y-axis.

DESCRIPTION
	   The XChangePointerDevice request causes the server to use the
	   specified device as the X pointer. The device must have been
	   opened by the client	via XOpenDevice	or a BadDevice error will
	   result. The device must support input class Valuators or a
	   BadMatch error will result. If the implementation does not
	   support use of the specified	device as the X	pointer, 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 =	MappingPointer is sent to all clients. The
	   specified device becomes the	X pointer, and the old X pointer
	   becomes accessible through the input	extension protocol
	   requests.

	   XChangePointerDevice	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 input
		  devices (pointer or keyboard). This error may	also occur
		  if the server	implementation does not	support	using the
		  specified device as the X pointer.

	   BadMatch
		  This error may occur if an XChangePointerDevice request
		  was made specifying a	device that has	less than two
		  valuators, or	specifying a valuator index beyond the
		  range	supported by the device.
