推荐答案

您是否已阅读msdn [ ^ ]?它清楚地表明，当使用mode ="w"打开文件时，"...如果给定文件存在，则其内容将被破坏." 所以我想您要做的就是打开再次归档.

Did you read the documentation for fopen in msdn[^]? It clearly says that when a file is open with mode = "w" then "... If the given file exists, its contents are destroyed." So I guess all you have to do is open the file again.

您的意思是每次打开文件都想拥有一个空文件吗?如果是，则只需以写入模式打开文件.请参阅文档 [

You mean you want to have an empty file each time you open the file ? If yes, then just open the file in write mode. See the documentation[^] for more info.
