写入硬盘，并检查错误退出（1）？ [英] Writing to the hard disk, and checking for error to exit(1)?
问题描述
（我在很长一段时间内没有做过C prorgamming，我已经忘记了
这样做了。）
我''我正在写一个程序，它用a +打开一个文件，我想
能够继续写入这个文件，但是我希望程序能够
exit（1）如果磁盘已满或其他写入失败。我想
来看一个C代码示例。提前致谢！
(I''ve not done C prorgamming in such a long time, I have forgotten how
to do this.)
I''m writing a program, where it fopens a file with "a+", and I want to
be able to continue writing to this file, but I want the program to
exit(1) if the disk is full or some other write failure. I would like
to see a C code example. Thanks in advance!

查找ferror（）。 Cf< stdio.h>
另外考虑使用EXIT_FAILURE而不是1. Cf< stdlib.h>

Look up ferror(). Cf <stdio.h>
Also consider using EXIT_FAILURE instead of 1. Cf <stdlib.h>

HPUX存在（仍然是？）问题，如果磁盘已满，则fprintf（）将阻止
，因此可能不总是工作。这种行为
是否符合标准？我只发现fprintf函数返回
传输的字符数，如果输出或
编码错误，则返回负值。

WYCIWYG - 你得到的是什么
There was (still is?) an issue with HPUX where fprintf() would block if
the disk got full, so this might not always work. Does this behaviour
conform to the Standard? I only found "The fprintf function returns the
number of characters transmitted, or a negative value if an output or
encoding error occurred."

它符合标准。但话说回来，
在每个陈述后等待三天的实施也可以符合标准。
It can conform to the standard. But then again, an implementation that
waits three days after each statement can also conform to the standard.
