[orca-list] Programatically detecting if Orca is running

[Nolan Darilek <nolan thewordnerd info>]

Hey folks,


I'm working on a game engine accessibility project that is essentially a 
screen reader running inside the engine. I'd like to enable my screen 
reader if I've detected that another is running. I know how to do this 
under Windows via Tolk, Android via accessibility APIs, but I'm not sure 
how to do this for Orca. Is there any way to detect whether Orca is 
running, or even better, if the user has indicated to GNOME/KDE that 
they'd like the screen reader active?


If there isn't an easy way, I'll probably just check for the presence of 
the various magical environment variables we've almost certainly got set 
to get things running, but I'd like to avoid that if possible.


And yes, I know I can technically check running processes, but that's 
hacky and I'd rather not. :)


Thanks.
