如何知道目录中有多少文件 [英] How to know how many files are into a directory
问题描述
我需要帮助。我想读取包含在目录中的文本文件，
但是我的程序不知道包含了多少文件。
在bash中有'类似于（弄清楚）的东西
for i in< dirdo
....
完成
但我不知道如何在C中做同样的事情。你能告诉我代码片段吗？

标准C甚至没有文件或目录的概念，所以
最好的方式来做你自己的事情要求是使用你的C库提供的文件管理
函数，否则就是你的操作系统。
POSIX定义的函数在大多数现代的
操作系统。您可以使用这些例程通过
名称读取目录中的文件，然后尝试访问每个文件。
确切的方法通常根据您的不同而有所不同平台。在适当的组中要求更多
详细信息。这个小组只处理标准C.

C没有任何处理目录的通用函数。
当然，大多数平台都有特定于系统的例程来执行此操作，
因此您需要在专业的平台组中询问。

调试的难度是首先编写代码的两倍。
因此，如果你尽可能巧妙地编写代码，那么，根据定义，它不够聪明，无法调试它。

Hi, I need help. I want to read text files contained into a directory,
but my program is unaware of how many files are contained into.
In bash there''s something similar to (figure out)
for i in <dirdo
....
done
but I don''t know how to do the same in C. Can you show me snippets of code?

the best manner to do what you''re asking is to use the file management
functions offered by your C library or, failing that, your OS.
Functions defined by POSIX are widely implemented under most modern
OSes. You can use these routines to read the files in a directory by
name and then try to access each one.
The exact method often varies according to your platform. Ask for more
detail in an appropriate group. This group deals only with standard C.

course most platforms do have system-specific routines for doing this,
so you need to ask in a group specialising in your platform.
