检查文件夹路径 [英] Check folder path

问题描述

我试图检查指定的路径是否存在。

I'm trying to check if the path given exists. In case it doesn't, I'd like to create a folder with name given in the same directory.

我们假设pathOne：/ home / music / A和pathTwo：/ home / music / B，使得文件夹A存在，但是文件夹B不存在。如果用户给定的路径是pathOne，则不会发生任何事情，但如果它的pathTwo，则程序应该意识到它不存在于/ home中，并且应该创建它。

Let's say pathOne: "/home/music/A" and pathTwo: "/home/music/B", such that folder A exists but folder B doesn't. Nothing happens if the path given by the user is pathOne, but if its pathTwo, then the program should realize that it doesn't exist in /home and should create it.

我知道可以检查文件的存在（使用fopen它可能做到），但我不知道如何做的文件夹！

I know that it's possible to check the existence from files (with fopen it's possible do to that), but I don't know how to do that for folders!

推荐答案

您应该能够使用 Boost文件系统存在功能。它也是可移植的。

You should be able to use Boost Filesystem exists function. It's also portable.

有一个非常好的教程描述这个场景，名为使用状态查询确定文件存在和类型 - （tut2.cpp）

There is a very good tutorial describing this very scenario, named Using status queries to determine file existence and type - (tut2.cpp)
