I do not like this patch, because it removes an error check. I think we 
have 3 possibilities here:
1) change dest_addr_len to int
2) use a temporary (int) variable to store the result of udp_set_url()
3) modify udp_set_url to return 0 on errror, and change the error check 
from "< 0" to "== 0".

I do not know which one of the 3 solutions is the best (I suspect it is 
just a matter of personal taste).

I am currently travelling, and I have no access to svn... I'll generate 
some patches implementing the above ideas on saturday or on monday, and 
I'll send them for review.
