*
|
|
* 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
|
|
* functions.
