2341 *
2342 * This table is generated using the helper macros defined above and with
2343 * generous help from the C pre-processor. The field name is stored as a string
2344 * into .name and for STR and INT types, the offset of the target buffer within
2345 * struct wpa_ssid is stored in .param1. .param2 (if not NULL) is similar
2346 * offset to the field containing the length of the configuration variable.
2347 * .param3 and .param4 can be used to mark the allowed range (length for STR
2348 * and value for INT).
2349 *
2350 * For each configuration line in wpa_supplicant.conf, the parser goes through
2351 * this table and select the entry that matches with the field name. The parser
2352 * function (.parser) is then called to parse the actual value of the field.
2353 *
2354 * This kind of mechanism makes it easy to add new configuration parameters,
2355 * since only one line needs to be added into this table and into the
2356 * struct wpa_ssid definition if the new variable is either a string or
2357 * integer. More complex types will need to use their own parser and writer
2358 * functions.
