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\&.
