问题出现了：
RETAILMSG(1, (TEXT("Outpw::: SetWR2dizhi..set..%x\r\n"),v_MCXPregs)); //打印地址d3620000
RETAILMSG(1, (TEXT("Outpw::: SetWR2dizhis2440MCX+1..set..%x\r\n"),(DWORD*)(v_MCXPregs+1)));//打印地址d3620020
RETAILMSG(1, (TEXT("Outpw::: SetWR2dizhis2440MCX+2..set..%x\r\n"),(DWORD*)(v_MCXPregs+2)));//打印地址d3620040
RETAILMSG(1, (TEXT("Outpw::: SetWR2dizhis2440MCX+3..set..%x\r\n"),(DWORD*)(v_MCXPregs+3)));//打印地址d3620080
RETAILMSG(1, (TEXT("Outpw::: SetWR2dizhis2440MCX+3..set..%x\r\n"),&v_MCXPregs->rMCXWR2));//打印地址d3620004
rMCXWR2地址是d3620004，和定义的偏移量一样，(DWORD*)(v_MCXPregs+1)怎么是d3620020，而不是我想要的d3d20001？？
如果我想访问d3620004，应该怎么偏移（不用v_MCXPregs->rMCXWR2）？？
