ZwQueryInfoMation函数很简单.就是4个参数.html
NTSTATUS WINAPI ZwQuerySystemInformation( _In_ SYSTEM_INFORMATION_CLASS SystemInformationClass, _Inout_ PVOID SystemInformation, _In_ ULONG SystemInformationLength, _Out_opt_ PULONG ReturnLength );
函数很简单.就4个参数. 参数已就是传个类型.表明你要查询什么类型.这个函数很强大.基本什么都是能够查询
参数2: 就是一个缓冲区.这个缓冲区是根据你查询的类型.当查询到数据.就会放到这个缓冲区.因此缓冲区能够接受你指定查询类型的数据.因此你想使用强转为同样的类型便可.
参数3: 缓冲区大小.
参数4: 返回大小windows
因此类别不少.可是MSDN不太全.看看下面吧. 能够定义类型.也有使用例子.ide
