Eliot Moss,
This worked perfectly:
char *dummy = NULL;

You're welcome, Sam.

It wouldn't be hard to implement clearenv() for a future release of

Indeed, this does not surprise me since environ is supposed
to be a pointer to an array of char *, whose last entry is
NULL. So the above line is the one needed. It *mig

Thank you Keith for you reply; but I am actually looking for the C APIs to

Sam,
Here is a short demonstration of how to detect unset (possibly null,
too?) variables in BASH. Not sure if this is exactly what you are
looking for but presented for info.
set -x;A_VAR="${RANDOM}";echo "1. ${A_VAR}";echo "2.
${A_VAR:?IS_NOT_SET}";unset A_VAR;set +x
