1507 | * | |
1508 | * This table is generated using the helper macros defined above and with | |
1509 | * generous help from the C pre-processor. The field name is stored as a string | |
1510 | * into .name and for STR and INT types, the offset of the target buffer within | |
1511 | * struct wpa_ssid is stored in .param1. .param2 (if not NULL) is similar | |
1512 | * offset to the field containing the length of the configuration variable. | |
1513 | * .param3 and .param4 can be used to mark the allowed range (length for STR | |
1514 | * and value for INT). | |
1515 | * | |
1516 | * For each configuration line in wpa_supplicant.conf, the parser goes through | |
1517 | * this table and select the entry that matches with the field name. The parser | |
1518 | * function (.parser) is then called to parse the actual value of the field. | |
1519 | * | |
1520 | * This kind of mechanism makes it easy to add new configuration parameters, | |
1521 | * since only one line needs to be added into this table and into the | |
1522 | * struct wpa_ssid definition if the new variable is either a string or | |
1523 | * integer. More complex types will need to use their own parser and writer | |
1524 | * functions. | |
