C++ boost-处理串行端口的文件结束错误（usb电缆重新连接）

我使用boost从串行端口读/写。设备通过USB（ttyACM0）连接。我的代码可以工作，但我不确定我是否正确处理了在读取过程中断开usb电缆时出现的文件结束错误。打开串行端口如下所示（我在这里只列出了代码中最重要的部分）：

以下是阅读功能：

void startRead()
{
   serialPort_.async_read_some(boost::asio::buffer(readSerialPortData_),
   boost::bind(&SerialPortAccess::readComplete, this, boost::asio::placeholders::error, boost::asio::placeholders::bytes_transferred));
}

void readComplete(const boost::system::error_code& error, size_t bytesTransferred)
{
   if (!error)
   {
      if (bytesTransferred > 0 && !readSerialPortData_.empty())
      {
         //handle data
      }
      startRead();
   }
   else
   {
      if(error == boost::asio::error::eof)
      {
         //async try to open serial port (someone may connect usb cable again), notify other thread (code presented above)
         open("/dev/ttyACM0");
      }
      else
      {
         close();
      }
   }
}

函数做什么？

void startRead()
{
   serialPort_.async_read_some(boost::asio::buffer(readSerialPortData_),
   boost::bind(&SerialPortAccess::readComplete, this, boost::asio::placeholders::error, boost::asio::placeholders::bytes_transferred));
}

void readComplete(const boost::system::error_code& error, size_t bytesTransferred)
{
   if (!error)
   {
      if (bytesTransferred > 0 && !readSerialPortData_.empty())
      {
         //handle data
      }
      startRead();
   }
   else
   {
      if(error == boost::asio::error::eof)
      {
         //async try to open serial port (someone may connect usb cable again), notify other thread (code presented above)
         open("/dev/ttyACM0");
      }
      else
      {
         close();
      }
   }
}
