为什么我们必须使用fclose（）？ [英] Why do we have to use fclose() ?

问题描述

为什么在文件关闭之前，即在调用fclose（）之前我无法看到文件内容，我尝试使用断点查看文件内容？



专家请帮助我...

Why I cant see the file content once it is written to a file before the file is closed i.e. before calling fclose() I tried to view the file content using breakpoints?

Experts Pls help me...

推荐答案

阅读文档：http://www.cplusplus.com/reference/cstdio/fclose/ [ ^ ]

读/写缓存在C / C ++（以及更多语言和操作系统）中，所以直到你关闭文件可能不完整（甚至部分已写入）...

Read/write are buffered in C/C++ (and in many more languages and OSs) so until you close the file it may not be complete (even parts of it are already written)...

MSDN：

所有缓冲区在关闭之前刷新与流关联的

all buffers associated with the stream are flushed prior to closing
