2337 *
2338 * This table is generated using the helper macros defined above and with

2340 * into .name and for STR and INT types, the offset of the target buffer within
2341 * struct wpa_ssid is stored in .param1. .param2 (if not NULL) is similar
2342 * offset to the field containing the length of the configuration variable.
2343 * .param3 and .param4 can be used to mark the allowed range (length for STR
2344 * and value for INT).
2345 *
2346 * For each configuration line in wpa_supplicant.conf, the parser goes through
2347 * this table and select the entry that matches with the field name. The parser
2348 * function (.parser) is then called to parse the actual value of the field.
2349 *
2350 * This kind of mechanism makes it easy to add new configuration parameters,
2351 * since only one line needs to be added into this table and into the
2352 * struct wpa_ssid definition if the new variable is either a string or
2353 * integer. More complex types will need to use their own parser and writer
2354 * functions.
