XISETCLIENTPOINTER(3)							    XISETCLIENTPOINTER(3)

NAME
       XISetClientPointer, XIGetClientPointer - set or get the ClientPointer device.

SYNOPSIS
       #include <X11/extensions/XInput2.h>

       XISetClientPointer( Display *display,
			   Window win,
			   int deviceid);

       Bool XIGetClientPointer( Display *display,
				Window win,
				int *device);

       display
	      Specifies the connection to the X server.

       win
	      Specifies a window belonging to the client. May be None.

       deviceid
	      Specifies the ClientPointer device.

DESCRIPTION
	   The ClientPointer is the device that is percieved to be the
	   core pointer for non-XI protocol requests and replies. Each
	   time a protocol message needs device-dependent data and the
	   device is not explicitly given, the ClientPointer device is
	   used to obtain the data. For example, a XQueryPointer request
	   will return the coordinates of the ClientPointer.

	   XISetClientPointer request sets the ClientPointer device for
	   the client that owns the given window. If win is None, the
	   requesting client's ClientPointer is set to the device
	   specified with deviceid. Only master pointer devices can be set
	   as ClientPointer.

	   XISetClientPointer and can generate a BadDevice and a BadWindow
	   error.

	   The XIGetClientPointer request returns the ClientPointer's
	   device ID for the client that owns the given window. If win is
	   None, the requesting client's ClientPointer is returned.

	   win may be a client ID instead of a window.

	   XIGetClientPointer can generate a BadWindow error.

DIAGNOSTICS
	   BadDevice
		  An invalid device was specified. The device does not
		  exist or is not a master pointer device.

	   BadWindow
		  A value for a Window argument does not name a defined
		  window.
