并且在写入文件期间将数据转储到文件中？

请提供一个例子

推荐答案

flush（）写入的内容缓冲区到目标并使缓冲区为空以便存储更多数据，但它不会永久关闭流。这意味着您仍然可以向流中写入更多数据。

flush() writes the content of the buffer to the destination and makes the buffer empty for further data to store but it does not closes the stream permanently. That means you can still write some more data to the stream.

但close（）会永久关闭流。如果你想进一步写一些数据，那么你必须再次重新打开流并用现有数据附加数据。

But close() closes the stream permanently. If you want to write some data further, then you have to reopen the stream again and append the data with the existing ones.
