Function Documentation

void gip_add_cidr (  guint32  ip, guint  bits, gpointer  udata )  [static]

ip_range_split() callback. Insert IP range in database, linking it to the proper country code.

void gip_changed (  const gchar *  filename, gpointer  unused )  [static]

Watcher callback, invoked when the file from which we read the geographic IP mappings changed.

void gip_close (  void   )

Frees all entries in the hostiles.

gint gip_country (  const host_addr_t  ha  )

Retrieves the country an address is assigned to. Parameters: ha  the host address to look up. Returns: the country mapped to this IP address as an numerical encoded country code, * or -1 when unknown.

void gip_init (  void   )

Called on startup. Loads the bogons.txt into memory.

gint gip_load (  FILE *  f  )  [static]

Load geographic IP data from the supplied FILE. Returns: The amount of entries loaded.

void gip_retrieve (  void   )  [static]

Loads the geo-ip.txt into memory. Choosing the first file we find among the several places we look at, typically: ~/.gtk-gnutella/geo-ip.txt /usr/share/gtk-gnutella/geo-ip.txt /home/src/gtk-gnutella/geo-ip.txt The selected file will then be monitored and a reloading will occur shortly after a modification.
