I think this define is pretty overkill..What about creating a function which only takes care of converting a generic DHT data in a string. Later you can invoke this function when you want to print an IPv4/6 using batadv_dbg.
Here is an example:
char *batadv_dat_data_to_str(struct batadv_dat_entry *dat_entry, const char *buf, size_t buf_len) { /* do something and put the string representation of the entry in the * buf, without exceeding buf_len. * Remember to use IS_ENABLED(CONFIG_IPV6) inside */
return buf;
}
Then you can call it directly as parameter of a batdv_dbg function. E.g:
batadv_dbg(....," %s\n", batadv_dat_data_to_str(entry, buf, buf_len));
I think this approach would be better and easy to extend for future data types. If you like this approach, what do you think about sending a patch now to add this function to the current code?
This could work. buf could be a string with a given pattern inside (let's say %data, or something similar) that would be automatically converted to the right type (like %pI4, or %pI6c.
mh..I did not quite get this..If you know how to implement this "pattern substitution" you can send a patch with that. Otherwise what I proposed above is just another way of doing that, which is at least simpler and easier to read than the macro you proposed before (imho)
