XIChangeHierarchy modifies the device hierarchy by creating or
|
|
removing master devices or changing the attachment of slave
|
|
devices. If num_changes is non-zero, changes is an array of
|
|
XIAnyHierarchyChangeInfo structures. If num_changes is equal or less than
|
|
zero, XIChangeHierarchy does nothing.

XIChangeHierarchy processes changes in order, effective
