RE: How read environment variable in .emacs?

[Bingham, Jay]

What you are looking for is getenv.

You really should learn to use the GNU Emacs Lisp Reference Manual.  I found 
the answer in there in less than 5 minutes (although I was pretty sure I knew 
it before I went looking).  If your system does not have it installed in the 
Info you can find it on the web at: 
http://www.gnu.org/manual/elisp-manual-20-2.5/ 
This is not the latest version but it is close.  I do not know when the latest 
version will be posted on the web.  Maybe some one will take the hint and get 
it posted soon.

I would like to read $DISPLAY in .emacs in a function
to know if emacs is running locally or remotely.

How do I do this???

(I've noticed local  => DISPLAY = :0
              remote => DISPLAY undefined )
