c++ - 我是否需要SE_SHUTDOWN_NAME特权才能注销用户？

我需要从C ++程序注销用户。我为此使用ExitWindowsEx API，但是我不确定文档是否需要特殊特权吗？

最佳答案

你做。这是一个例子

bool ShutdownWindows(void)
{
HANDLE hToken = NULL;
TOKEN_PRIVILEGES tkp = {0};
bool bRet = false;

// Get a token for this process.
if (OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken)) {
    if (LookupPrivilegeValue(NULL, SE_SHUTDOWN_NAME, &tkp.Privileges[0].Luid)) {
        tkp.PrivilegeCount = 1;  // one privilege to set
        tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;

        // Get the shutdown privilege for this process.
        if (AdjustTokenPrivileges(hToken, FALSE, &tkp, 0, NULL, 0)) {
            ::CloseHandle(hToken);

            if (ERROR_SUCCESS == GetLastError()) {

                DWORD dwFlags = EWX_POWEROFF;
                DWORD dwReason = SHTDN_REASON_MAJOR_SYSTEM;

                if (ExitWindowsEx(dwFlags, dwReason)) {
                    bRet = true;
                }
            }
        }
    }
}

return bRet;

} // ShutdownWindows
