       indicator maps associated with an input extension device

SYNOPSIS
       Status XkbGetDeviceInfoChanges ( dpy, device_info, changes )

	     XkbDeviceInfoPtr device_info;
	     XkbDeviceChangesPtr 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 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.
