获取文件的所有者和组使用boost [英] Get file's owner and group using boost

问题描述

我想使用boost ::文件系统从一个文件的所有者和组，但从来没有发现任何方式这样做。

I want to get the owner and group from a file using boost::filesystem, but never found any way to do so.

我可以获取该文件的权限，但我不知道该文件的所有者只是这并不意味着什么。

I can get the file's permissions, but as I don't know the file's owner this just doesn't mean anything.

我找到了POSIX FSTAT功能，但同样我想使用升压或其他C ++库，而不是C函数。

I found the posix fstat function, but again I'd like to use boost or another C++ library rather than C functions.

推荐答案

什么你问做的是一个Unix系统调用。但是，你不想把它？为什么？什么可能值可能推动提供？这不是便携性，如无一个Unix之外将会有一个有意义的st_gid场。

What you're asking to do is a Unix system call. But you don't want to call it? Why? What possible value could boost provide? It's not portability, as nothing outside of a Unix is going to have a meaningful st_gid field.
