environment variables

[Syed Imranullah Azeezullah <s i azeezullah massey ac nz>]

Hi all,

How do I set environment variables from within a gtk application?
Assume that I want to to be able to set EDITOR to vi/emacs from within
my gtk app and then I want any new terminal / application opened in the
window manager to have the same value for EDITOR until I close my window
manager to end my session.

Is it possible? and is it window manager specific?

Regards,
Imran
