Hello Matt,

Thanks for following up.  My recommendation is to say something like:

This function DOES NOT securely erase the contents of the environment.
Security-conscious applications which need to do this should use ....
instead.
Thanks for your reply. To match the note recommending a solution of 
withdrawal, then I suggest:

-----

If it is unavailable the assignment

     environ = NULL;

will probably do.

But these solutions DO NOT securely erase the contents of the 
environment. ecurity-conscious applications which need to do this should 
use [...] instead.

Problem, I have no idea of good security practice. A helping hand, please?

Regards,
