1778 * offset to the field containing the length of the configuration variable.
1779 * .param3 and .param4 can be used to mark the allowed range (length for STR
1780 * and value for INT).
1781 *
1782 * For each configuration line in wpa_supplicant.conf, the parser goes through
1783 * this table and select the entry that matches with the field name. The parser
1784 * function (.parser) is then called to parse the actual value of the field.
1785 *
1786 * This kind of mechanism makes it easy to add new configuration parameters,

1788 * struct wpa_ssid definition if the new variable is either a string or
1789 * integer. More complex types will need to use their own parser and writer
1790 * functions.
