I think the conclusion was > that the current implimentation was correct. See: Not sure about that. But going to <http://www.opengroup.org/>; and finding the Single UNIX Specification online and searching for relevant manual pages, putenv() is there whilst setenv() isn't.

This is what led me to find this in the first place. *sighs* -- Phil Pennock <pdp@nl.demon.net> <Phil.Pennock@thus.net> Demon Internet Nederland -- Network Operations Centre -- Systems Administrator Libertes philosophica.
