Function Documentation

struct wpa_config* wpa_config_read

(

const char *

name

)

[read]

Read and parse configuration database.

Parameters:

name

Name of the configuration (e.g., path and file name for the configuration file)

Returns:

Pointer to allocated configuration data or NULL on failure

This function reads configuration data, parses its contents, and allocates data structures needed for storing configuration information. The allocated data can be freed with wpa_config_free().

Each configuration backend needs to implement this function.

int wpa_config_write	(	const char *	name,
		struct wpa_config *	config
	)

Write or update configuration data.

Parameters:

	name	Name of the configuration (e.g., path and file name for the configuration file)
	config	Configuration data from wpa_config_read()

Returns:

0 on success, -1 on failure

This function write all configuration data into an external database (e.g., a text file) in a format that can be read with wpa_config_read(). 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.
