1799 * .param3 and .param4 can be used to mark the allowed range (length for STR
1800 * and value for INT).
1801 *
1802 * For each configuration line in wpa_supplicant.conf, the parser goes through

1804 * function (.parser) is then called to parse the actual value of the field.

1809 * integer. More complex types will need to use their own parser and writer
1810 * functions.
