1508 * This table is generated using the helper macros defined above and with

1510 * into .name and for STR and INT types, the offset of the target buffer within

1514 * and value for INT).
1516 * For each configuration line in wpa_supplicant.conf, the parser goes through
1517 * this table and select the entry that matches with the field name. The parser
1518 * function (.parser) is then called to parse the actual value of the field.
1520 * This kind of mechanism makes it easy to add new configuration parameters,
1521 * since only one line needs to be added into this table and into the
1522 * struct wpa_ssid definition if the new variable is either a string or
1523 * integer. More complex types will need to use their own parser and writer
