1646 * that is inside a network block.
1647 *
1648 * This table is generated using the helper macros defined above and with
1649 * generous help from the C pre-processor. The field name is stored as a string
1650 * into .name and for STR and INT types, the offset of the target buffer within
1651 * struct wpa_ssid is stored in .param1. .param2 (if not NULL) is similar
1652 * offset to the field containing the length of the configuration variable.
1653 * .param3 and .param4 can be used to mark the allowed range (length for STR
1654 * and value for INT).
1655 *
1656 * For each configuration line in wpa_supplicant.conf, the parser goes through
1657 * this table and select the entry that matches with the field name. The parser
1658 * function (.parser) is then called to parse the actual value of the field.
1659 *
1660 * This kind of mechanism makes it easy to add new configuration parameters,
1661 * since only one line needs to be added into this table and into the
1662 * struct wpa_ssid definition if the new variable is either a string or
1663 * integer. More complex types will need to use their own parser and writer
1664 * functions.
