TA,你给的这个头文件中，这个函数怎么调用？
看了好长时间，你给的这个.h文件看出点眉目了但是还有一些不会用
比如这个函数KvGetKernelVoid是干什么用的？
怎么调用？ 本帖最后由 ok100fen 于 2010-8-30 14:34 编辑

就在这里的
上面红色的函数是调用内核函数地址的？
给举个例子吧
3q KvGetKernelVoid(NtOpenProcess);
DbgPrint("NtOpenProcess的原始地址3=%x.",KvGetKernelVoid(NtOpenProcess));
我这么调用编译不了
怎么办？ OK爷爷,您搞不清楚啊?
TA那个是sssdt.h,我这个是KernelVoid.h,我这个是修改过的,不是TA的.
是我为了方便加了个Kv******,原来是没有的.
