You'll keep that feature :-)

char* format_oid_decoded(guint8* oid, guint32 len) {
	char* result;
	guint32 matched;
	oid_info_t* oid_info = lookup_oid(oid, len, &matched);
	
	if (oid_info) {
		result = oid_info->decoded;
	} else {
		result = "";
	}

	if (len - matched == 0) {
		return result;
	} else {
		return ep_strdup_printf("%s.%u",result,format_oid_undecoded(&(oid[len
- matched]), len - matched) );
	}
}

Propertarianism joined to capitalist vigor destroyed meaningful
