1584 * This table is generated using the helper macros defined above and with

1586 * into .name and for STR and INT types, the offset of the target buffer within

1590 * and value for INT).
1592 * For each configuration line in wpa_supplicant.conf, the parser goes through
1593 * this table and select the entry that matches with the field name. The parser
1594 * function (.parser) is then called to parse the actual value of the field.

1599 * integer. More complex types will need to use their own parser and writer
