The changes->changed field indicates which attributes of the device specified in changes->device have changed. The parameters describing the changes are contained in the other fields of changes. XkbGetDeviceInfoChanges uses that information to call XkbGetDeviceInfo to obtain the current status of those attributes that have changed. It then updates the local description of the device in device_info with the new information.
