There's no (simple, portable, supported) way to alter a process's
environment variables from a subprocess.  The best you can do is
to write the information into a pipe, file, FIFO, or some such and
make the parent shell pick up that information.

Without knowing exactly why you want to do this, I cannot give more
specific advice.  It's possible that you're trying to do something
the hard way...
