# 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 | Writes the destination SRAM address (address on the AGB memory map).
src | Writes the source work area address.
size | 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.
Note that the AGB backup device cannot be accessed normally with version IS-NITRO-DEBUGGER 1.66 or earlier.
