# CTRDG_WriteAndVerifyAgbSram

## C Specification

      #include <nitro/ctrdg.h>

      u32 CTRDG_WriteAndVerifyAgbSram(u32 dst, const void* src, u32 size);

      Corresponding AGB function: u32 WriteSramEx(u8 *dst, u8 *src, u32 size)

## Arguments

dst | Represents the target SRAM address (address on the AGB memory map)
src | Represents the source work area address
size | Represents the size of data written/verified in bytes

## Return Values

Returns 0 if verification succeeds. Returns the error address on the device side if verification fails.

## Description

Internally, after data is written by CTRDG_WriteAgbSram, verification is performed by CTRDG_VerifyAgbSram. If there is an error, the function retries up to the number of times specified by CTRDG_AGB_SRAM_RETRY_MAX (defined in AgbSram.h).

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.)
