It's not a C++-style API, but the API you aren't finding (the Linux/Unix correspondent of DOS/Windows-style findfirst/findnext) is opendir/readdir/closedir.

The main advantage of using opendir/readdir/closedir is that you do not need any extra library (it's part of the C library, which you are already using). In fact, the Boost filesystem library uses opendir/readdir/closedir to get the list of files in a directory.

The STL does not, yet, have functions for listing files in a directory. But it does have functions for opening files you are already aware of.

blocks|key|5430374|text|由于C%2B%2B17，标准库包含std::filesystem，它的源代码在Boost.Filesystem中。如今，std::filesystem::directory_iterator是显而易见的选择，因为它是独立于平台的，提供了比_findfirst/findnext/opendir/readdir/closedir更好的抽象，并且没有引入任何依赖。如果您不能使用与C%2B%2B17兼容的编译器，那么现在使用Boost，以后再切换。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|5430375|entityMap|0|LINK|mutability|MUTABLE|url|https://en.cppreference.com/w/cpp/filesystem|1|https://www.boost.org/doc/libs/1_77_0/libs/filesystem/doc/index.htm|2|https://en.cppreference.com/w/cpp/filesystem/directory_iterator|3|https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/findfirst-functions|4|https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/findnext-functions?view=msvc-|5|https://pubs.opengroup.org/onlinepubs/009695399/functions/opendir.html|6|http://www.opengroup.org/onlinepubs/009695399/functions/readdir.html|7|http://www.opengroup.org/onlinepubs/009695399/functions/closedir.html^0|D|F|Z|G|1K|Z|37|A|3I|8|3R|7|3Z|7|47|8|D|F|0|Z|G|1|1K|Z|2|37|A|3|3I|8|4|3R|7|5|3Z|7|6|47|8|7|0^^$0|@$1|2|3|4|5|6|7|11|8|@$9|12|A|13|B|C]|$9|14|A|15|B|C]|$9|16|A|17|B|C]|$9|18|A|19|B|C]|$9|1A|A|1B|B|C]|$9|1C|A|1D|B|C]|$9|1E|A|1F|B|C]|$9|1G|A|1H|B|C]]|D|@$9|1I|A|1J|1|1K]|$9|1L|A|1M|1|1N]|$9|1O|A|1P|1|1Q]|$9|1R|A|1S|1|1T]|$9|1U|A|1V|1|1W]|$9|1X|A|1Y|1|1Z]|$9|20|A|21|1|22]|$9|23|A|24|1|25]]|E|$]]|$1|F|3|-4|5|6|7|26|8|@]|D|@]|E|$]]]|G|$H|$5|I|J|K|E|$L|M]]|N|$5|I|J|K|E|$L|O]]|P|$5|I|J|K|E|$L|Q]]|R|$5|I|J|K|E|$L|S]]|T|$5|I|J|K|E|$L|U]]|V|$5|I|J|K|E|$L|W]]|X|$5|I|J|K|E|$L|Y]]|Z|$5|I|J|K|E|$L|10]]]]

Since C++17 the standard library contains <a href="https://en.cppreference.com/w/cpp/filesystem" rel="nofollow noreferrer"><code>std::filesystem</code></a> which has its source in <a href="https://www.boost.org/doc/libs/1_77_0/libs/filesystem/doc/index.htm" rel="nofollow noreferrer"><code>Boost.Filesystem</code></a>. Nowadays <a href="https://en.cppreference.com/w/cpp/filesystem/directory_iterator" rel="nofollow noreferrer"><code>std::filesystem::directory_iterator</code></a> is the obvious choice since it is platform-independent, offers better abstraction than <a href="https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/findfirst-functions" rel="nofollow noreferrer"><code>_findfirst</code></a>/<a href="https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/findnext-functions?view=msvc-" rel="nofollow noreferrer"><code>findnext</code></a>/<a href="https://pubs.opengroup.org/onlinepubs/009695399/functions/opendir.html" rel="nofollow noreferrer"><code>opendir</code></a>/<a href="http://www.opengroup.org/onlinepubs/009695399/functions/readdir.html" rel="nofollow noreferrer"><code>readdir</code></a>/<a href="http://www.opengroup.org/onlinepubs/009695399/functions/closedir.html" rel="nofollow noreferrer"><code>closedir</code></a> and doesn't introduce any dependencies. If you can't use a C++17-compliant compiler use Boost for now and switch over later.

I can't seem to find the _findfirst / findfirst, _findnext / findnext API on gcc for Linux, and would actually rather use the Standard Template Library (STL) for that if it is included there.

Does anyone know what API there is available for listing files in a directory under Linux for C++ (gcc)?

Is there a standard way to do findfirst, findnext with gcc on linux using stl?

我似乎找不到在gcc上的_findfirst / findfirst，_findnext / findnext API，实际上我更愿意使用标准模板库(STL)来实现它，如果它包含在那里的话。有没有人知道在Linux for C++ (gcc)下有什么接口可以列出目录中的文件？

问在linux上用stl对gcc做findfirst，findnext有没有标准的方法？
