ZwQueryInfoMation函数很简单.就是4个参数.
代码语言：javascript复制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.代表你要查询什么类型.这个函数很强大.基本什么都是可以查询 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.所以缓冲区可以接受你指定查询类型的数据.所以你想使用强转为一样的类型即可. 参数3: 缓冲区大小. 参数4: 返回大小
所以类别很多.但是MSDN不太全.看看下面吧. 可以定义类型.也有使用例子.
