1120 They must have an additional description indicating the type of
1121 alternative configuration the string represents,
1122 "ALTCFG=<StringToken>". That <StringToken> (when

1139 ConfigHdr reference will be returned in the Results Field.

1356 This function is called to provide results data to the driver.
1357 This data consists of a unique key that is used to identify
1358 which data is either being passed back or being asked for.
1359
1360 @param This Points to the EFI_HII_CONFIG_ACCESS_PROTOCOL.
1361 @param Action Specifies the type of action taken by the browser.
1362 @param QuestionId A unique value which is sent to the original
1363 exporting driver so that it can identify the type
1364 of data to expect. The format of the data tends to
1365 vary based on the opcode that generated the callback.
1366 @param Type The type of value for the question.
1367 @param Value A pointer to the data being sent to the original
1368 exporting driver.
1369 @param ActionRequest On return, points to the action requested by the
1370 callback function.
1371
1372 @retval EFI_SUCCESS The callback successfully handled the action.
1373 @retval EFI_OUT_OF_RESOURCES Not enough storage is available to hold the
1374 variable and its data.
1375 @retval EFI_DEVICE_ERROR The variable could not be saved.
1376 @retval EFI_UNSUPPORTED The specified Action is not supported by the
1377 callback.
