Routine Description:
This function processes the results of changes in configuration.
Arguments:
This - Points to the EFI_HII_CONFIG_ACCESS_PROTOCOL.
Action - Specifies the type of action taken by the browser.
QuestionId - A unique value which is sent to the original exporting driver
so that it can identify the type of data to expect.
Type - The type of value for the question.
Value - A pointer to the data being sent to the original exporting driver.
ActionRequest - On return, points to the action requested by the callback function.
Returns:
EFI_SUCCESS - The callback successfully handled the action.
EFI_OUT_OF_RESOURCES - Not enough storage is available to hold the variable and its data.
EFI_DEVICE_ERROR - The variable could not be saved.
EFI_UNSUPPORTED - The specified Action is not supported by the callback.
