1800 | * into .name and for STR and INT types, the offset of the target buffer within | |

1802 | * offset to the field containing the length of the configuration variable. | |
1803 | * .param3 and .param4 can be used to mark the allowed range (length for STR | |
1804 | * and value for INT). | |
1805 | * | |
1806 | * For each configuration line in wpa_supplicant.conf, the parser goes through | |
1807 | * this table and select the entry that matches with the field name. The parser | |
1808 | * function (.parser) is then called to parse the actual value of the field. | |
1809 | * | |

1812 | * struct wpa_ssid definition if the new variable is either a string or | |
