Thank you, that worked just fine:
int is_dtls(SSL *ssl)
{
return NULL != BIO_find_type(SSL_get_rbio(ssl), BIO_TYPE_DGRAM);
}
Cheers!

Well getting the version number is one way but you have to check more than one
version if it can use the broken version number of for OpenSSL 1.0.2
(it supports DTLS 1.2 as well).
A similar way to that already suggested is to check the type of BIO used. If
it is a datagram BIO it's DTLS, if socket TLS but that avoids any system
calls.
