This can be used to allow wpa_supplicant to update its configuration, e.g., when a new network is added or a password is changed. Each configuration backend needs to implement this function.

struct wpa_ssid* wpa_config_add_network

(

struct wpa_config *

config

)

[read]

wpa_config_add_network - Add a new network with empty configuration : Configuration data from wpa_config_read() Returns: The new network configuration or NULL if operation failed

Definition at line 1751 of file config.c.

int wpa_config_add_prio_network	(	struct wpa_config *	config,
		struct wpa_ssid *	ssid
	)

wpa_config_add_prio_network - Add a network to priority lists : Configuration data from wpa_config_read() : Pointer to the network configuration to be added to the list Returns: 0 on success, -1 on failure

This function is used to add a network block to the priority list of networks. This must be called for each network when reading in the full configuration. In addition, this can be used indirectly when updating priorities by calling wpa_config_update_prio_list().

)

wpa_config_free - Free configuration data : Configuration data from wpa_config_read()

This function frees all resources allocated for the configuration data by wpa_config_read().

Definition at line 1684 of file config.c.

Definition at line 2078 of file config.c.

void wpa_config_free_ssid

(

struct wpa_ssid *

ssid

)

wpa_config_free_ssid - Free network/ssid configuration data : Configuration data for the network

This function frees all resources allocated for the network configuration data.

wpa_config_get_all - Get all options from network configuration : Pointer to network configuration data : Determines if keys/passwords will be included in returned list Returns: NULL terminated list of all set keys and their values in the form of [key1, val1, key2, val2, ... , NULL]

This function can be used to get list of all configured network properties. The caller is responsible for freeing the returned list and all its elements.
