得到的m68k RAM地址用C语言特定字节 [英] Get specific byte from M68k ram address with C language

问题描述

通过IDA反汇编我已经达到了这个地址：

Through the IDA disassembler I've reached this address:

0010FD74  00 00 00 00 00 00 03 00  00 00 00 00 82 03 80 02

现在我需要的，给予特别得到字节地址;例如第7位置有03。
我已经用C语言做这个尝试：

Now I need, given the address to get particular bytes; for example the 7th position where there is "03". I've tried using C language to do this:

char *dummycharacter;
*dummycharacter = *(char*)0x10FD74;

现在，如果我尝试用它来访问第七值：

Now if I try to access 7th value with this:

dummycharacter[6]

我不明白×03 ......我要去哪里错了？

I don't get 0x03…where am I going wrong?

推荐答案

您正在尝试的值赋给 dummycharacter 点（这是pretty太多无处，因为它不是初始化）。尝试 dummycharacter =（字符*）0x10FD74;

You're trying to assign the value dummycharacter points to (which is pretty much nowhere, since it's not initialized). Try dummycharacter = (char*)0x10FD74;.
