  protected:
    ACE_WIN32_Asynch_Timer (
        ACE_Handler &handler,
        const void *act,
        const ACE_Time_Value &tv,
        ACE_HANDLE event = ACE_INVALID_HANDLE,
        int priority = 0,
        int signal_number = 0
        );
    virtual void complete (
        u_long bytes_transferred,
        int success,
        const void *completion_key,
        u_long error = 0
        );
    ACE_Time_Value time_;
};
```
