I am learning to use SSL & UDP. After some extensive search, I couldn't find many sample programs to test and study. In fact, the only one I found is this. http://openssl.6102.n7.nabble.com/DTLS-examples-td2143.html However, although the author claimed it is non-blocking, after reading the code I don't think it is what we usually mean because it does not use select() or poll() at all. Would like to have some help here, really appreciated.

Here are the code samples I found dtls samples Hope this helps.
