This copying is a bit pointless at the moment, but I'm assuming that's
because this is just RFC, right?
no. I replace the '.' by \0 and have in buf two strings (pointed by
func_name and instance_name). I can't do this replacement "name"
because it is const.
+ func_name = buf;
+ instance_name = strstr(func_name, ".");
strchr(func_name, '.')

Could the ifdef logic be reversed? Ie. have #ifdef rather than #ifndef?
