You can't, I'm afraid.  It's unfortunate that Linux does not implement
this function.  Instead, use getenv(3) as you would for any other
environment variable.

P.S.: "Unix" or "unix-like" is a generic term for all of these systems.
In this case there is a distinction between the BSD family of Unix
versions and Linux, but one wouldn't say that it's only "available in
Unix, but not in Linux".
