Subject: PSARC FastTrack [11/23/2006]: addition of res_ndestroy() to libresolv.so.2

I am sponsoring this fasttrack for Stacey Marshall. Given the trivial
nature of change, I am going to close approved automatic unless I hear
otherwise.

4. Technical Description

Problem:

Libresolv leeks memory as there is no public interface to release it.

Details:

Function res_ninit() dynamically extends the res_state structure by
allocating additional memory and storing the address in a previously
unused and undocumented portion of res_state.  Currently there is no
formal way to free this resource when it is no longer required.

Proposal:

In line with the ISC we will make res_ndestroy() a public interface and
document it accordingly.

Affected interfaces:

Interface            Stability        Comments
================================================================================
res_ndestroy()       Volatile        As provided by the ISC


Release binding: patch.

Man page changes in case directory.
