I'm not sure about that, but I do know that there is a stdlib.h function
(it's an ANSI function, btw) called getenv to which you pass a string
containing the evironment variable you're interested in, and it returns a
pointer to the string containing it's value (or NULL if it doesn't
exist).

It seems like there should be some kind of function to allow you to just
browse through them all without knowing the name of each variable, in
case you just want to look over what variables there are, but I don't
recall any.
