1590 | * | |

1593 | * into .name and for STR and INT types, the offset of the target buffer within | |

1595 | * offset to the field containing the length of the configuration variable. | |
1596 | * .param3 and .param4 can be used to mark the allowed range (length for STR | |
1597 | * and value for INT). | |
1598 | * | |
1599 | * For each configuration line in wpa_supplicant.conf, the parser goes through | |
1600 | * this table and select the entry that matches with the field name. The parser | |

1605 | * struct wpa_ssid definition if the new variable is either a string or | |
