我有以下一组特定于Windows的代码，

    //1: Declaring HANDLE
    HANDLE *m_handle;
    
   //2: Creating HANDLE instance   
   int m_Count = 4;
   m_handle = new HANDLE[m_Count];

   //3: Creating Events
   for (int i = 0; i < m_Count ; i++)
    {
        m_handle [i] = CreateEvent(NULL, FALSE, FALSE, NULL);
    }

   //4: Synchronous API
   DWORD dwEvent = WaitForMultipleObjects(m_Count, m_handle, TRUE, 30000);

   //5: Closing the HANDLE
   for (int i = 0; i < m_Count; i++)
    {
        CloseHandle(m_handle[i]);
    }

如何在Linux的情况下编写相同的代码集？
