       indicator names and indicator maps associated with an input extension device

SYNOPSIS
       Status XkbGetDeviceInfoChanges ( dpy, device_info, changes )

DESCRIPTION
       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 XkbGetDevi-
       ceInfo 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.
