Function Documentation

void free_networks (  void   )  [static]

frees the local networks array

void host_add (  const host_addr_t  addr, guint16  port, gboolean  do_connect )

Add a new host to our pong reserve. When `connect' is true, attempt to connect if we are low in Gnet links.

void host_add_semi_pong (  const host_addr_t  addr, guint16  port )

Add a new host to our pong reserve, although the information here does not come from a pong but from a Query Hit packet, hence the port may be unsuitable for Gnet connections.

void host_close (  void   )

gint host_cmp (  gconstpointer  v1, gconstpointer  v2 )

Compare function which returns 0 if the hosts are equal, otherwise 1. Note: For use in g_list_find_custom.

gint host_eq (  gconstpointer  v1, gconstpointer  v2 )

Compare function which returns TRUE if the hosts are equal. Note: For use in g_hash_table_new.

guint host_hash (  gconstpointer  key  )

Hash function for use in g_hash_table_new.

void host_init (  void   )

gboolean host_is_nearby (  const host_addr_t  addr  )

Returns: true if the address is inside one of the local networks

gboolean host_is_valid (  const host_addr_t  addr, guint16  port )

Check whether host is connectible. i.e. that it has a valid port and that its IP address is not private not bogus.

void host_shutdown (  void   )

Signals that we're shutdowning and entering a grace period, during which we don't need to make any new connection.

void host_timer (  void   )

Periodic host heartbeat timer.

const gchar* host_to_string (  const gnet_host_t *  h  )

Returns: the address:port of a host

void parse_netmasks (  const gchar *  str  )

Break the netmaks string and convert them into network_pair elements in the local_networks array. IP's are in network order.

RCSID (  "$Id:hosts.  c, v 1.21 2005/09/11 13:39:57 rmanfredi Exp $"  )
