+ * const char *remote_ip_addr,
+ * int remote_port,
+ * SilcSchedule schedule,
+ * SilcNetCallback callback,

+ *
+ * DESCRIPTION
+ *
+ * Creates TCP/IP connection to the remote host indicated by `remote_host'
+ * which may be hostname or IP address, on the port indicated by
+ * `remote_port'. If the `local_ip_addr' is provided the local host is
+ * bound to that address before creating the connection. This is
+ * asynchronous call, and this function returns before the connection is
+ * actually established. The `callback' will be called after the
+ * connection is created to deliver the SilcStream for the created
+ * connection. This function supports IPv6 if the platform supports it.
+ *
+ * The returned SilcAsyncOperation context can be used to control the
+ * asynchronous connecting, such as to abort it. If it is aborted
+ * using silc_async_abort the `callback' will not be called. If NULL
+ * is returned the operation cannot be aborted. If `schedule' is NULL
+ * this will call silc_schedule_get_global to try to get global scheduler.

+ * SilcStream
+ * silc_net_udp_connect(const char *local_ip_addr, int local_port,
+ * const char *remote_ip_addr, int remote_port,
+ * SilcSchedule schedule);
+ *
+ * DESCRIPTION
+ *
+ * This function creates UDP stream. The UDP stream is bound to the
+ * `local_ip_addr' if it is specified. If `local_port' is non-zero the
+ * stream is bound to that port. If the `remote_ip_addr' and `remote_port'
+ * is also provided, packets may be sent to that address using
+ * silc_stream_write function and packets may be received using
+ * silc_stream_read function.
+ *
+ * If the remote address is not provided the stream is in connectionless
+ * state. This means that packets can be received only by using
+ * silc_net_udp_receive and sent only by using the function
+ * silc_net_udp_send.
+ *
+ * To receive packets the silc_stream_set_notifier must be called for the
+ * returned SilcStream. The packets are always received in the notifier
+ * callback when the SILC_STREAM_CAN_READ is returned to the callback
+ * To read the packet use silc_stream_read if the remote address was
+ * provided, and silc_net_udp_receive if it was not.
+ *
+ * Supports IPv6 if the platform supports it. If `schedule' is NULL this
+ * will call silc_schedule_get_global to try to get global scheduler.
