2053 * Table of network configuration variables. This table is used to parse each
2054 * network configuration variable, e.g., each line in wpa_supplicant.conf file
2055 * that is inside a network block.
2056 *
2057 * This table is generated using the helper macros defined above and with
2058 * generous help from the C pre-processor. The field name is stored as a string
2059 * into .name and for STR and INT types, the offset of the target buffer within
2060 * struct wpa_ssid is stored in .param1. .param2 (if not NULL) is similar
2061 * offset to the field containing the length of the configuration variable.
2062 * .param3 and .param4 can be used to mark the allowed range (length for STR
2063 * and value for INT).
2064 *
2065 * For each configuration line in wpa_supplicant.conf, the parser goes through
2066 * this table and select the entry that matches with the field name. The parser
2067 * function (.parser) is then called to parse the actual value of the field.
2068 *
2069 * This kind of mechanism makes it easy to add new configuration parameters,
2070 * since only one line needs to be added into this table and into the
2071 * struct wpa_ssid definition if the new variable is either a string or
2072 * integer. More complex types will need to use their own parser and writer
2073 * functions.

2931 * the same format that the text-based configuration file and wpa_config_set()
