I know that unsetenv() can be changed without problems since it has no return value at the moment. The others are more difficult but not impossible. I see that a mild discussion has occurred on cvs. :) Here are both scenarios with my code changes: BSD[1] (only unsetenv() is updated to return an int. Easy to change back) POSIX[2] (all *env() functions are updated to reflect POSIX) Sean 1. http://www.farley.org/freebsd/tmp/setenv-8/BSD/sysenv.c 2. http://www.farley.org/freebsd/tmp/setenv-8/POSIX/sysenv.c -- sean-freebsd@farley.org
