2396 * into .name and for STR and INT types, the offset of the target buffer within
2397 * struct wpa_ssid is stored in .param1. .param2 (if not NULL) is similar
2398 * offset to the field containing the length of the configuration variable.
2399 * .param3 and .param4 can be used to mark the allowed range (length for STR
2400 * and value for INT).
2401 *
2402 * For each configuration line in wpa_supplicant.conf, the parser goes through
2403 * this table and select the entry that matches with the field name. The parser
2404 * function (.parser) is then called to parse the actual value of the field.
2405 *
2406 * This kind of mechanism makes it easy to add new configuration parameters,
2407 * since only one line needs to be added into this table and into the
2408 * struct wpa_ssid definition if the new variable is either a string or
2409 * integer. More complex types will need to use their own parser and writer
2410 * functions.
