You mean process's p_comm value, right ? I guess it's not
worth the efford to find the argv[0].

Is the name available to the kernel somehow ?

I'd probably prefer something vaguely related to printf() format's,
i.e. %s for the name of process, %d for pid. Or avoid those funny
%foo altogether and use plain strings 'progname', 'pid',
'username'/'uid'. Consider how much more readable is
'progname-pid.core' than '%n-%p.core'.
