[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,

	)

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().
