+ * SYNOPSIS
+ *
+ * SilcPacketStream silc_packet_stream_add_remote(SilcPacketStream stream,
+ * const char *remote_ip,
+ * SilcUInt16 remote_port);
+ *
+ * DESCRIPTION
+ *
+ * This function is used to add remote receivers in packet stream `stream'
+ * that has UDP/IP socket stream as the underlaying stream. This function
+ * cannot be used with other type of streams. This returns new packet
+ * stream context that can be used to send to and receive packets from
+ * the specified remote IP and remote port, or NULL on error. The `stream'
+ * is the actual stream that is used to send and receive the data.
+ *
+ * When the parent `stream' receives packets from remote IP address
+ * and port that does not have its own remote packet stream, it returns
+ * the packet to the packet callback set for `stream'. The sender's
+ * IP address and port can then be retrieved by using the
+ * silc_packet_stream_get_sender function and to create new packet
+ * stream by calling this function. After that, all packets from that
+ * IP address and port will be received by the new packet stream.
+ *
+ * This interface is for connectionless UDP streams. If it is possible
+ * to create connected stream it should be done for performance reasons.
+ *
+ * EXAMPLE
+ *
+ * // Create parent packet stream, it can receive packets from anywhere
+ * listener = silc_net_udp_connect("0.0.0.0", 500, NULL, 0, schedule);
+ * parent = silc_packet_stream_create(engine, schedule, listener);
+ *
+ * ...
+ * // Received a packet to the parent stream, get the sender information.
+ * silc_packet_stream_get_sender(parent, &ip, &port);
+ *
+ * // Create new packet stream for this remote location.
+ * remote = silc_packet_stream_set_remote(parent, ip, port);
