在WINDOWS2000中如何调用函数使其关机AND重新启动！

Windows 2000还是WIN32，还是用ExitWindowsEx。

具体一点

[haihong]

BOOL ExitWindowsEx(
UINT uFlags, // shutdown operation
DWORD dwReserved // reserved
);


uFlags
Specifies the type of shutdown. This parameter must include one of the following values: Value Meaning
EWX_LOGOFF Shuts down all processes running in the security context of the process that called the ExitWindowsEx function. Then it logs the user off.
EWX_POWEROFF Shuts down the system and turns off the power. The system must support the power-off feature.
Windows NT: The calling process must have the SE_SHUTDOWN_NAME privilege. For more information, see the following Remarks section.

EWX_REBOOT Shuts down the system and then restarts the system.
Windows NT: The calling process must have the SE_SHUTDOWN_NAME privilege. For more information, see the following Remarks section.

EWX_SHUTDOWN Shuts down the system to a point at which it is safe to turn off the power. All file buffers have been flushed to disk, and all running processes have stopped.
Windows NT: The calling process must have the SE_SHUTDOWN_NAME privilege. For more information, see the following Remarks section.



This parameter can optionally include the following values: Value Meaning
EWX_FORCE Forces processes to terminate. When this flag is set, the system does not send the WM_QUERYENDSESSION and WM_ENDSESSION messages. This can cause the applications to lose data. Therefore, you should only use this flag in an emergency.
EWX_FORCEIFHUNG Windows NT 5.0 and later: Forces processes to terminate if they do not respond to the WM_QUERYENDSESSION or WM_ENDSESSION message. This flag is ignored if EWX_FORCE is used.

在W2K中关机会失败，原因是应用程序权限不够。我想只有设法改变权限才行。
查查以Access开头的API吧。

最好有一段通过的code!

查一下<<windows API>>

Win2000关机与WIN NT4.0关机应该是一致的因为Win2000其实是Win NT5.0。具体方法可以参见《新潮电子》第四期的文章《VC++实现退出Win NT》

你需取得授权。这是我的一段源程序：
OSVERSIONINFO oi;
oi.dwOSVersionInfoSize = sizeof(OSVERSIONINFO);
GetVersionEx(&oi);
if (oi.dwPlatformId == VER_PLATFORM_WIN32_NT)
//if ((ver & 0x0000ffff) == ver and and (ver & 0x0000ffff) == 5)
{
HANDLE handle;
TOKEN_PRIVILEGES tkp;

OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES and TOKEN_QUERY, &handle);
LookupPrivilegeValue(NULL, SE_SHUTDOWN_NAME, &tkp.Privileges[0].Luid);

tkp.PrivilegeCount = 1; // one privilege to set
tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;

AdjustTokenPrivileges(handle, FALSE, &tkp, 0, (PTOKEN_PRIVILEGES)NULL, 0);
}
::ExitWindowsEx(flag, 0);

注：其中的flag是我在前边定义的，根据选选择是重起机还是关机设定。这段程序可在NT和2000下运行。
