272 * part of the environment table directly...it will use this specific
273 * buffer, and not a copy of it! This means you can't free it, and
274 * other pieces of code may try to write to it. In practice, this
275 * isn't a big deal, but be aware of the possibility.
276 * However, due to this issue, you should be prepared to
277 * pass a (char*), or be willing to cast away the constness of your
