设置系统的时间？

请问在驱动程序中，哪一个函数能够直接设置系统的时间？
请各位高手指点一下！！

高手，不对啊，我看了你转发的文章，我在驱动程序中如下声明了该函数，但是，程序编译时有错误；能够看一下这个函数应该
怎样声明，才能够把他使用起来？谢谢啦！！
extern BOOL SetSystemTime(CONST SYSTEMTIME *lpSystemTime);
我是这样调用的，是编译有错。编译器认不到BOOL 类型。
NTSTATUS SDDevice::IOCTL_SET_SYSTEM_TIME_Handler(KIrp I)
{
   NTSTATUS status = STATUS_SUCCESS;
    SYSTEMTIME time;
    time.wYear = 2000;
    time.wMonth = 1;
    time.wDayOfWeek = 1;
    SetSystemTime(&time);
    I.Information() = 0;
    return status;
}

error C2146: syntax error : missing \';\' before identifier \'SetSystemTime\'
C:\\Documents and Settings\\Administrator\\桌面\\418\\SD2407\\sys\\SD2407Device.cpp(1298) : fatal error C1004: unexpected end of file found
Error executing cl.exe.

SD2407.sys - 2 error(s), 0 warning(s)

我也没有用过这个函数的，，不是说在USER32。DLL里的吗。。。

你找到这个函数对应的声明的头文件，，包进去。。还有定义那个结构的文件哦。。。。

bool改成BOOLEAN   试试。。

还有啊。。你SetSystemTime(&time);不对吧？

改成SetSystemTime(time);吧，，应该。。。

刚注意到哦，，你这是用DS写驱动那？

那这个函数可以在DS驱动开发中用吗？。。。这可是个用户模式的函数。。。好像不可以这么用的啊。。。。

嗯！，，应该不可以用的，，没有试验过。。呵呵

对应该不能够在驱动程序中调用它，我现在还想问一个问题就是驱动
程序中又没有能够直接修改系统时间的函数，因为在应用程都提供了
SetSystemTime（）函数可以设置系统时间，我总觉得在驱动程序中
也应该有这个功能的函数才行啊，我看了ddk和ds的帮助文档,只有ddk里说了可以调用函数KeQuerySystemTime()来读取系统的时间，可是就没有找到能够设置系统时间的函数？

就得没有直接调用的函数，，那就不好弄了。。。

你非要完成这个功能吗？。。。让那些搞核心编程的老大们。。

来看 看吧。。。。这东西，，俺不是很懂的了。。呵呵。。。

ZwSetSystemTime
ZwSetSystemTime sets the system time.
NTSYSAPI
NTSTATUS
NTAPI
ZwSetSystemTime(
IN PLARGE_INTEGER NewTime,
OUT PLARGE_INTEGER OldTime OPTIONAL
);
Parameters
NewTime
Points to a variable that specifies the new time of day in the standard time format (that
is, the number of 100-nanosecond intervals since January 1, 1601).
OldTime
Optionally points to a variable that receives the old time of day in the standard time
format (that is, the number of 100-nanosecond intervals since January 1, 1601).
Return Value
Returns STATUS_SUCCESS or an error status, such as STATUS_PRIVILEGE_NOT_HELD.
Related Win32 Functions
SetSystemTime.
Remarks
SeSystemtimePrivilege is required to set the system time.

可惜,没有早点看到这个贴子,否则分就是我的啦!

老歌从哪里找的，DDK文档中没有，是不是在Native Api那本书里，我找到一大堆，KeSetSystemTime,NtSetSystemTime,ZwSetSystemTime，不知他们被输出了吗？

输出了,但DDK的头文件中没有相应的声明,你要自己写。（拷贝、粘贴）。 :)
