I found out, that jabberd2 uses libudns library to make queries.

Is it full list of symbols, that proxychains hooks?
SETUP_SYM(connect);
SETUP_SYM(gethostbyname);
SETUP_SYM(getaddrinfo);
SETUP_SYM(freeaddrinfo);
SETUP_SYM(gethostbyaddr);
SETUP_SYM(getnameinfo);
SETUP_SYM(close);

I haven't found any in code of libudns. If, for example, there is some not-hooked function in library, and I add it to proxychains, will this functions get hooked? Or there is no way to hook functions, that is loaded from dynamic library?
