XChangePointerDevice(3X11)
X11R6
NAME
  XChangePointerDevice - change which device is the X pointer

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

ARGUMENTS
  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.
