Status XChangePointerDevice\^(\^Display *\fIdisplay\fP\^, XDevice
22
*\fIdevice\fP\^, int \fIxaxis\fP\^, int \fIyaxis\fP\^);
27
Specifies the connection to the X server.
30
Specifies the device to be used as the X pointer.
33
Specifies the axis of the device to be used as the X pointer x-axis.
36
Specifies the axis of the device to be used as the X pointer y-axis.
38
The \fIXChangePointerDevice\fP request causes the server to use the specified
39
device as the X pointer. The device must have been opened by the client via
40
\fIXOpenDevice\fP or a \fIBadDevice\fP error will result. The device must
41
support input class \fIValuators\fP or a \fIBadMatch\fP error will result.
42
If the implementation does not support use of the specified device as the
43
X pointer, a \fIBadDevice\fP error will result.
45
If the specified device is grabbed by another client, \fIAlreadyGrabbed\fP
46
is returned. If the specified device is frozen by a grab on another device,
47
\fIGrabFrozen\fP is returned.
48
If the request is successful, \fISuccess\fP is returned.
50
If the request succeeds,
51
a \fIChangeDeviceNotify\fP event is sent to all clients that have selected that
52
event. A \fIMappingNotify\fP event with request = \fIMappingPointer\fP is
54
The specified device becomes the X pointer, and
55
the old X pointer becomes accessible through the input extension
58
\fIXChangePointerDevice\fP can generate a \fIBadDevice\fP or a \fIBadMatch\fP
63
An invalid device was specified. The specified device does not exist, has
64
not been opened by this client via \fIXOpenInputDevice\fP, or is already
65
one of the core X input devices (pointer or keyboard). This error may also
66
occur if the server implementation does not support using the specified
67
device as the X pointer.
70
This error may occur if an \fIXChangePointerDevice\fP request was made
71
specifying a device that has less than two valuators, or specifying a
72
valuator index beyond the range supported by the device.

The XChangePointerDevice request causes the server to use the
64
specified device as the X pointer\&. The device must have been
65
opened by the client via XOpenDevice or a BadDevice error will
66
result\&. The device must support input class Valuators or a

AlreadyGrabbed is returned\&. If the specified device is frozen
81
by a grab on another device, GrabFrozen is returned\&. If the
82
request is successful, Success is returned\&.
92
If the request succeeds, a ChangeDeviceNotify event is sent to
93
all clients that have selected that event\&. A MappingNotify
94
event with request = MappingPointer is sent to all clients\&. The
95
specified device becomes the X pointer, and the old X pointer

if the server implementation does not support using the
