- * @brief Creates a new DTLS session
- *
- *  Initiates a handshake with a DTLS server at @p ep and wait until it
- * completes or timed out.
- *
- * @deprecated Will not be available after the 2020.10 release.
- *             Please use @ref sock_dtls_session_init() and
- *             @ref sock_dtls_recv() instead.
- *
- * @param[in]  sock     DLTS sock to use
- * @param[in]  ep       Remote endpoint of the session
- * @param[out] remote   The created session, cannot be NULL
- * @param[in]  timeout  Timeout to wait for handshake to finish.
- *                      Returns immediately if 0.
- *                      May be SOCK_NO_TIMEOUT to wait indefinitely until
- *                      handshake complete.
- *
- * @return  0 on success
- * @return  -ENOMEM, if no memory to allocate for new peer
- * @return  -EADDRNOTAVAIL, if the local endpoint of @p sock is not set.
- * @return  -EINVAL, if @p remote is invalid or @p sock is not properly
- *          initialized (or closed while sock_udp_recv() blocks).
