2107 * that is inside a network block.
2108 *
2109 * This table is generated using the helper macros defined above and with
2110 * generous help from the C pre-processor. The field name is stored as a string
2111 * into .name and for STR and INT types, the offset of the target buffer within
2112 * struct wpa_ssid is stored in .param1. .param2 (if not NULL) is similar
2113 * offset to the field containing the length of the configuration variable.
2114 * .param3 and .param4 can be used to mark the allowed range (length for STR
2115 * and value for INT).
2116 *
2117 * For each configuration line in wpa_supplicant.conf, the parser goes through
2118 * this table and select the entry that matches with the field name. The parser
2119 * function (.parser) is then called to parse the actual value of the field.
2120 *
2121 * This kind of mechanism makes it easy to add new configuration parameters,
2122 * since only one line needs to be added into this table and into the
2123 * struct wpa_ssid definition if the new variable is either a string or
2124 * integer. More complex types will need to use their own parser and writer
2125 * functions.
