# CARD_GetResultCode

## C Specification

  `#include <nitro/card.h>`
  `CARDResult CARD_GetResultCode(void);`

## Arguments

None.

## Return Values

Returns the result of the last process run by the function that accesses the CARD ROM device and the backup device.

## Description

This function returns the result of the last process that is run by the function that accesses the CARD ROM device and the backup device. From the result value that is obtained with this function, the success or failure of the process and the detailed cause of the failure can be determined.
This function allows these functions to obtain the result value. However, the functions that are shown in green will always have a return value of `CARD_RESULT_SUCCESS`; therefore, it is not necessary to explicitly determine the value of the result.

    These functions access the backup device:

    [EEPROM]
    CARD_ReadEeprom

    CARD_ReadEepromAsync

    CARD_WriteEeprom

    CARD_WriteEepromAsync

    CARD_VerifyEeprom

    CARD_VerifyEepromAsync

    CARD_WriteAndVerifyEeprom

    CARD_WriteAndVerifyEepromAsync

    [FLASH]
    CARD_ReadFlash

    CARD_ReadFlashAsync

    CARD_WriteFlash

    CARD_WriteFlashAsync

    CARD_VerifyFlash

    CARD_VerifyFlashAsync

    CARD_WriteAndVerifyFlash

    CARD_WriteAndVerifyFlashAsync

    [Common]
    CARD_IdentifyBackup
    CARD_LockBackup
    CARD_UnlockBackup

    These functions access the ROM device:

    CARD_LockRom
    CARD_UnlockRom
    CARD_ReadRom
    CARD_ReadRomAsync

Of the functions mentioned above, the result value of the last called function is the return value for this function. These return values do not change if functions other than the above mentioned CARD functions are called.
