The XChangePointerDevice request causes the server to use the
|
|
specified device as the X pointer\&. The device must have been
|
|
opened by the client via XOpenDevice or a BadDevice error will
|
|
result\&. The device must support input class Valuators or a
|
|
BadMatch error will result\&. If the implementation does not
|
|
support use of the specified device as the X pointer, a
|
|
BadDevice error will result\&.

An invalid device was specified\&. The specified device

XOpenInputDevice, or is already one of the core X input

devices (pointer or keyboard)\&. This error may also occur
