Function silc_net_udp_send SYNOPSIS
        int silc_net_udp_send(SilcStream stream,
                              const char *remote_ip_addr, int remote_port,
                              const unsigned char *data, SilcUInt32 data_len);
DESCRIPTION
        Sends an UDP packet to remote host `remote_ip_addr' on `remote_port'.
        This may be used with UDP streams that are not connected to any
        specific remote host.  With those stream silc_stream_write cannot be
        used.  In those cases, this function must be used.  This may also be
        used even if the stream is connected.

        Returns the amount of data written, -1 if data could not be written
        at this moment, or -2 if error occurred.  If -1 is returned the
        notifier callback will later be called with SILC_STREAM_CAN_WRITE
        status when stream is again ready for writing.
