1373 * This table is generated using the helper macros defined above and with

1375 * into .name and for STR and INT types, the offset of the target buffer within
1376 * struct wpa_ssid is stored in .param1. .param2 (if not NULL) is similar

1378 * .param3 and .param4 can be used to mark the allowed range (length for STR
1379 * and value for INT).
1381 * For each configuration line in wpa_supplicant.conf, the parser goes through
1382 * this table and select the entry that matches with the field name. The parser
1383 * function (.parser) is then called to parse the actual value of the field.
1385 * This kind of mechanism makes it easy to add new configuration parameters,

1387 * struct wpa_ssid definition if the new variable is either a string or
1388 * integer. More complex types will need to use their own parser and writer
