NAME
     XChangePointerDevice - change which device is the X pointer

SYNOPSIS
     cc [ flag... ] file... -lXi [ library... ]

     #include 

     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.
