This function is called by the forms browser in response to a user action on a question which has the
EFI_IFR_FLAG_CALLBACK bit set in the EFI_IFR_QUESTION_HEADER. The user action is specified by Action.
Depending on the action, the browser may also pass the question value using Type and Value. Upon return,
the callback function may specify the desired browser action. Callback functions should return
EFI_UNSUPPORTEDfor all values of Action that they do not support.
@param This Points to the EFI_HII_CONFIG_ACCESS_PROTOCOL.
@param Action Specifies the type of action taken by the browser.
@param QuestionId A unique value which is sent to the original exporting driver so that it can identify the
type of data to expect. The format of the data tends to vary based on the opcode that
generated the callback.
@param Type The type of value for the question.
@param Value A pointer to the data being sent to the original exporting driver. The type is specified
by Type. Type EFI_IFR_TYPE_VALUE is defined in EFI_IFR_ONE_OF_OPTION.
@param ActionRequest On return, points to the action requested by the callback function. Type
EFI_BROWSER_ACTION_REQUEST is specified in SendForm() in the Form Browser Protocol.
@retval EFI_SUCCESS The callback successfully handled the action.
@retval EFI_OUT_OF_RESOURCES Not enough storage is available to hold the variable and its data.
@retval EFI_DEVICE_ERROR The variable could not be saved.
@return EFI_UNSUPPORTED The specified Action is not supported by the callback.
