+ * SilcNetListener
+ * silc_net_tcp_create_listener2(const char *local_ip_addr, int *ports,
+ * SilcUInt32 port_count,
+ * SilcBool ignore_port_error,
+ * SilcBool lookup, SilcBool require_fqdn,
+ * SilcSchedule schedule,
+ * SilcNetCallback callback, void *context);
+ *
+ * DESCRIPTION
+ *
+ * This function creates TCP listener. This is used to create network
+ * listener for incoming connections, and `callback' will be called
+ * everytime new connection is received. If `local_ip_addr' is NULL 'any'
+ * address is used. If `ports' is NULL or it contains a zero (0) port,
+ * operating system will define it automatically. This function can be
+ * used to bind to many ports at the same time. If `ignore_port_error'
+ * is TRUE this won't return NULL if at least one of the ports could
+ * be bound. Otherwise, NULL will be returned on error.
+ *
+ * If `require_fqdn' is TRUE the listener will require that the incoming
+ * connection has FQDN to be able to connect. If the `lookup' is TRUE
+ * then the incoming connection hostname will be resolved.
+ *
+ * The `callback' always delivers valid new stream. It is not called
+ * with an error status.

* SYNOPSIS
* to get the port if none was specified in silc_net_tcp_create_listener.
* Returns an array of ports of size of `port_count'. The caller must
* free the array with silc_free. There are as many ports in the array
- * as there were IP addresses provided in silc_net_tcp_create_listener.
+ * as there were IP addresses provided in silc_net_tcp_create_listener,
+ * as there were ports provided in silc_net_tcp_create_listener2.
