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