# CTRDG_VerifyAgbFlashAsync

## C Specification

      #include <nitro/ctrdg.h>

      void CTRDG_VerifyAgbFlashAsync(u16 sec_num, u8* src, u32 size, CTRDG_TASK_FUNC callback);

## Arguments

sec_num | The destination flash sector number.
src | Writes the source address.
size | The verify size in bytes.
callback | The callback function called when verify processing ends.

## Return Values

None.

## Description

This function asynchronously verifies data of the size in size beginning from the address given by src against the data in sec_num.
You can find out whether the verify process succeeded by accessing the result member of the `CTRDGTaskInfo` structure used as an argument to the callback function that returns after this routine is called.
It is 0 if the verify process succeeded, non-zero if the process failed, and the error address on the device side if the verify process resulted in an error.

The access cycle setting is created in the function and does not need to be set beforehand.

Note: The cartridge bus is locked for a set period by this function.

Note that the AGB backup device cannot be accessed normally with version IS-NITRO-DEBUGGER 1.66 or earlier.
