Adding a Connection Field to the SDP Session Structure

int sdp_add_connection(sdp_conn_t **conn, const char *nettype,
            const char *addrtype, const char *address, uint8_t ttl,
            int addrcount);

The sdp_add_connection() function adds the CONNECTION (c=) SDP field to either the session structure (sdp_session_t) or the media structure (sdp_media_t) using the nettype, addrtype, address, ttl, and addrcount parameters. For IPv4 or IPv6 unicast addresses, set the values of the ttl and addrcount parameters to zero. For multicast addresses, set the value of the ttl parameter between zero and 255. A multicast address cannot have an addrcount parameter with a value of zero.
