static void conf_error	(	cfg_t *	cfg,
		const char *	fmt,
		va_list	ap
	)			[static]

reports errors during config file parsing using LOG macro

Parameters:

	cfg	points to the current config data structure
	fmt	a format string
	ap	format arguments

int load_config

(

struct route_data_t *

rd

)

Loads the routing data from the config file given in global variable config_data and stores it in routing tree rd.

Parameters:

rd

Pointer to the route data tree where the routing data shall be loaded into

Returns:

0 means ok, -1 means an error occured

static cfg_t* parse_config

(

void

Parses the config file

Returns:

a pointer to the configuration data structure, NULL on failure

int save_config

(

struct route_data_t *

rd

)

Stores the routing data rd in config_file

Parameters:

rd

Pointer to the routing tree which shall be saved to file

Returns:

0 means ok, -1 means an error occured

static int save_route_data_recursor	(	struct dtrie_node_t *	node,
		FILE *	outfile
	)			[static]

Does the work for save_config, traverses the routing data tree and writes each rule to file.

Parameters:

	node	the current prefix tree node
	outfile	the filehandle to which the config data is written

Returns:

0 on success, -1 on failure
