getaddrinfo and TTL

	Can one read the TTL for a given lookup in

	Better yet, is there a listing of the entire range of
values one can read from all the structures?

	I wrote an application years ago to let us change the
name of a host. The old code uses zone transfer to pull in the
whole zone, actually several zones in to a pile of A records. We
look for the old name, replace it with the new name and then do
a delete and add.

	If getaddrinfo contains this value, the replace
application can run much faster, just doing one lookup, and the
new record we write back will keep whatever value we originally

Many thanks.
