我们知道user mode是不可能直接访问内核地址的,cpu在将虚地址翻译成物理地址的时候会检查特权级,user mode是第3级而内核是第0级,倘若第三级的指令带的地址是第0级,cpu会抛拒绝访问的异常。反过来,内核指令访问user mode地址虽然可行,不过得考虑进程上下文,如果你不管进程上下文直接访问user mode地址,有两种错误情况...

You can readily switch to the source window for IoCtl’s IRP handler, but suppose you want to see an earlier routine? You bring up the calls window (ViewàCall stack), so: You can double-click on an entry and be taken to the source file, if that source file can be located. ...
