* the code looks for know locations. It can be explicitely set/overrided with
|
|
* the KCONFIG_PATH environment variable as well.
|
|
*
|
|
* The caller has to initialize the tst_kconfig_var structure. The id has to be
|
|
* filled with config variable name such as 'CONFIG_FOO', the id_len should
|
|
* hold the id string length and the choice and val has to be zeroed.
|
|
*
|
|
* After a call to this function each choice be set as follows:
|
|
*
|
|
* 'm' - config option set to m
|
|
* 'y' - config option set to y
|
|
* 'v' - config option set to other value
|
|
* 'n' - config option is not set
|
|
* 0 - config option not found
|
|
*
|
|
* In the case that match is set to 'v' the val pointer points to a newly
|
|
* allocated string that holds the value.

* @param vars An array of caller initalized tst_kconfig_var structures.

* @param vars_len Length of the vars array.
