1753 | * into .name and for STR and INT types, the offset of the target buffer within | |
1754 | * struct wpa_ssid is stored in .param1. .param2 (if not NULL) is similar | |
1755 | * offset to the field containing the length of the configuration variable. | |
1756 | * .param3 and .param4 can be used to mark the allowed range (length for STR | |
1757 | * and value for INT). | |
1758 | * | |
1759 | * For each configuration line in wpa_supplicant.conf, the parser goes through | |
1760 | * this table and select the entry that matches with the field name. The parser | |
1761 | * function (.parser) is then called to parse the actual value of the field. | |
1762 | * | |

1765 | * struct wpa_ssid definition if the new variable is either a string or | |
