I'm presuming that you want to get xattr of files that are open in Ada. That 
means that you have to have some cooperation from your vendor, in that Ada 
does not make implementation artifacts like file handles available. Some 
implementations might have a way to get those, some might not.

The problem is much easier if you just want to get xattr based on file 
names, because then one could write a binding to do just that, and avoid any 
interaction with the Ada implementation.
