Sorry, maybe I should have been more clear: I'm looking for an elisp
variable or function that tells me that exwm is active.  Yes, I can
drill down into the operating system (as Basile has suggested) and the
process environment but I had imagined that there would something along
the lines of `exwmp` or similar.  I just cannot find such which I find
surprising but maybe I have not searched effectively.

For the record, in any case,

none of these environment variables gives anything useful.  Obviously, I
can set my own environment variable, say WM=exwm (or =stumpwm etc.) and
maybe that's what I'll end up doing.

Thank you,
eric
