.SH "DESCRIPTION"
.sp
.if n \{\
.RS 4
.\}
.nf
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\&.
.fi
.if n \{\
.RE
.\}
.sp
.if n \{\
.RS 4
.\}
.nf
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\&.

.sp
.if n \{\
.RS 4
.\}
.nf
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\&.
.fi
.if n \{\
.RE

.sp
.if n \{\
.RS 4

win may be a client ID instead of a window\&.

XIGetClientPointer can generate a BadWindow error\&.

.SH "DIAGNOSTICS"
.sp
.if n \{\

.nf
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\&.
