gboolean scan_extensions_changed (  property_t  prop  )  [static]

void settings_addr_changed (  const host_addr_t  new_addr, const host_addr_t  peer )

This routine is called when we determined that our IP was no longer the one we computed. We base this on some headers sent back when we handshake with other nodes, and as a result, cannot trust the information. What we do henceforth is trust 3 successive indication that our IP changed, provided we get the same information each time. --RAM, 13/01/2002 Parameters: `new_addr'  the newly suggested address. `peer'  the IP address of peer which reported the new IP address. There must be 3 peers from 3 different /16 networks before a change is accepted. Otherwise, it would be very easy to confuse GTKG by connecting 3 times in a row and submitting a *wrong* IP address. --cbiere, 2004-08-01

void settings_ask_for_property (  const gchar *  name, const gchar *  value )

Ask them to set a property to be able to run.

void settings_close (  void   )

Finally free all memory allocated. Call after settings_shutdown.

const gchar* settings_config_dir (  void   )

Get the config directory.

guint64 settings_getphysmemsize (  void   )  [static]

Returns: the amount of physical RAM in KB, or zero in case of failure

const gchar* settings_home_dir (  void   )

Gets the home dir.

void settings_init (  void   )

guint32 settings_max_msg_size (  void   )

Maximum message payload size we are configured to handle.

void settings_remove_pidfile (  void   )  [static]

Remove pidfile.

void settings_save_if_dirty (  void   )

Save settings if dirty.

void settings_shutdown (  void   )

Called at exit time to flush the property files.
