* DESCRIPTION
*
- * SILC Net API provides various network routines for applications. It
- * can be used to create TCP/IP connections and servers. Various utility
- * functions for resolving various information is also provided.
+ * SILC Net API provides various network routines for applications. It can
+ * be used to create TCP/IP and UDP/IP connections and listeners. Various
+ * utility functions for resolving various information is also provided.
+ * The interface supports both IPv4 and IPv6.
*
- * On WIN32 systems the SILC Net API must initialized by calling the
- * silc_net_win32_init and uninitialized when the application ends by
- * calling the silc_net_win32_uninit function. The initializing must be
- * done in order to assure that the SILC Net API works correctly.
+ * EXAMPLE
+ *
+ * // Create TCP connection to example.com at port 25
+ * silc_net_tcp_connect(NULL, "example.com", 25, schedule, connected_cb, ctx);
+ *
+ * // Create UDP listener on local interface 10.2.1.7 on port 500
+ * SilcStream udpstream;
+ *
+ * udpstream = silc_net_udp_connect("10.2.1.7", 500, NULL, 0, schedule);
+ * silc_stream_set_notifier(udpstream, schedule, receive_callback, ctx);

+ * 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'

+ * 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_ip_addr' was
+ * provided, and silc_net_udp_receive if it was not.
