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

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

       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.  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.
