41 This function allows a caller to extract the current configuration for one
42 or more named elements from the target driver.
45 @param This Points to the EFI_HII_CONFIG_ACCESS_PROTOCOL.
46 @param Request A null-terminated Unicode string in <ConfigRequest> format.
47 @param Progress On return, points to a character in the Request string.
48 Points to the string's null terminator if request was successful.
49 Points to the most recent '&' before the first failing name/value
50 pair (or the beginning of the string if the failure is in the
51 first name/value pair) if the request was not successful.
52 @param Results A null-terminated Unicode string in <ConfigAltResp> format which
53 has all values filled in for the names in the Request string.
54 String to be allocated by the called function.
56 @retval EFI_SUCCESS The Results is filled with the requested values.
57 @retval EFI_OUT_OF_RESOURCES Not enough memory to store the results.
58 @retval EFI_INVALID_PARAMETER Request is NULL, illegal syntax, or unknown name.

78 @param This Points to the EFI_HII_CONFIG_ACCESS_PROTOCOL.
79 @param Configuration A null-terminated Unicode string in <ConfigResp> format.
80 @param Progress A pointer to a string filled in with the offset of the most
81 recent '&' before the first failing name/value pair (or the
82 beginning of the string if the failure is in the first
83 name/value pair) or the terminating NULL if all was successful.

106 @param Action Specifies the type of action taken by the browser.
107 @param QuestionId A unique value which is sent to the original exporting driver
108 so that it can identify the type of data to expect.
109 @param Type The type of value for the question.
110 @param Value A pointer to the data being sent to the original exporting driver.
111 @param ActionRequest On return, points to the action requested by the callback function.
113 @retval EFI_SUCCESS The callback successfully handled the action.
114 @retval EFI_OUT_OF_RESOURCES Not enough storage is available to hold the variable and its data.
115 @retval EFI_DEVICE_ERROR The variable could not be saved.
