OK.  Still not terribly hard:

    {
        static char const exe_fmt[] =3D
            "/proc/%d/exe";
        char bf[sizeof (exe_fmt) + 12];
        sprintf(bf, exe_fmt, getpid());
        path_len =3D readlink(bf, exe_path, sizeof (exe_path) - 1);
    }

(This is for Linux only...)

Ah!  There we go.  That's what I was looking for.  Thank you!
