I tried it before, and I tried it recently - it definitely doesn't work

Thats already a simple solution for my problem. So I can call
emacsclient generically without the '-s' option in my program and tell
my users that the emacs-daemon they want to connect to must be started
with server-name 'server'.

I have the same 'server-socket-dir', so hardcoding this works fine on my
machine. But what if I need a generic version? Can I get the value of
`server-socket-dir' and use it for the '-s' option in the same external
call to emacsclient? Or would I need two consecutive calls to
emacsclient, the first one reading the value of `server-socket-dir' via
'emacsclient -e "(...some lisp...)"', the second one using it for the
'-s' option from a variable of the calling program?

Anyway, supposing that the adressed emacs-server is called 'server' is
probably the simplest and best solution. Thanks for your help.
