1757 * This table is generated using the helper macros defined above and with

1759 * into .name and for STR and INT types, the offset of the target buffer within
1760 * struct wpa_ssid is stored in .param1. .param2 (if not NULL) is similar
1761 * offset to the field containing the length of the configuration variable.
1762 * .param3 and .param4 can be used to mark the allowed range (length for STR
1763 * and value for INT).
1764 *
1765 * For each configuration line in wpa_supplicant.conf, the parser goes through
1766 * this table and select the entry that matches with the field name. The parser
1767 * function (.parser) is then called to parse the actual value of the field.
1768 *
1769 * This kind of mechanism makes it easy to add new configuration parameters,
1770 * since only one line needs to be added into this table and into the
1771 * struct wpa_ssid definition if the new variable is either a string or
1772 * integer. More complex types will need to use their own parser and writer
1773 * functions.
