# CTRDG_VerifyAgbSramAsync

## C Specification

      #include <nitro/ctrdg.h>

      void CTRDG_VerifyAgbSramAsync(u32 tgt, const void* src, u32 size, CTRDG_TASK_FUNC callback);

## Arguments

tgt | Represents a pointer to the SRAM address to be verified (data to be written, address in the AGB memory map)
src | Represents a pointer to the verification source work area address (original data)
size | Represents the size of data verified in bytes
callback | Represents the callback function called after verify processing ends

## Return Values

None.

## Description

This function asynchronously verifies data of the size given by "size" from the address in the work area given by "src" against the data at the address given by "tgt" in SRAM.
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.
This function returns 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.
In addition, the AGB backup device cannot be accessed normally by the IS-NITRO-DEBUGGER.
However, be sure to check operations using an actual DS handheld unit since normal access is possible with actual DS units. (This will be fixed in a future version of IS-NITRO-DEBUGGER.)
