Function Documentation

struct wpa_config* wpa_config_read (  const char *  name  )

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. Definition at line 213 of file config_file.c. Here is the call graph for 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.
