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.
