1798 * This table is generated using the helper macros defined above and with

1800 * into .name and for STR and INT types, the offset of the target buffer within
1801 * struct wpa_ssid is stored in .param1. .param2 (if not NULL) is similar
1802 * offset to the field containing the length of the configuration variable.
1803 * .param3 and .param4 can be used to mark the allowed range (length for STR
1804 * and value for INT).
1805 *
1806 * For each configuration line in wpa_supplicant.conf, the parser goes through
1807 * this table and select the entry that matches with the field name. The parser
1808 * function (.parser) is then called to parse the actual value of the field.
1809 *
1810 * This kind of mechanism makes it easy to add new configuration parameters,
1811 * since only one line needs to be added into this table and into the
1812 * struct wpa_ssid definition if the new variable is either a string or
1813 * integer. More complex types will need to use their own parser and writer
1814 * functions.
