43<P>Asynchronously verifies data of the size in <SPAN class="argument">size</SPAN> beginning from the address given by <SPAN class="argument">src</SPAN> against the data in <SPAN class="argument">sec_num</SPAN>.<br>You can find out whether the verify process succeeded by accessing the result member of the <CODE>CTRDGTaskInfo</CODE> structure used as an argument to the callback function that returns after this routine is called. <br>It returns zero 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.</P>
44<P>The access cycle setting is created in the function and does not need to be set in advance.</P>
45<P><B>Note:</B> The cartridge bus is locked for a set period by this function.</P>
46<P>Note that the AGB backup device cannot be accessed normally with IS-NITRO-DEBUGGER version 1.66 or earlier.</P>
