How do I check if a directory is a file or folder?
提问by William
Okay, so I'm using mingW, and the direct struct has no variables named d_type or stat, d_stat, or dd_stat. I need to know how I can use my direct struct to figure out if what I have is a file or folder. Here is my code.
好的，所以我使用 mingW，并且直接结构没有名为 d_type 或 stat、d_stat 或 dd_stat 的变量。我需要知道如何使用我的直接结构来确定我拥有的是文件还是文件夹。这是我的代码。
#include <sys/types.h>
#include <sys/stat.h>
#include <dirent.h>
#include <errno.h>
#include <vector>
#include <string>
#include <iostream>
using namespace std;
/*function... might want it in some class?*/
int getdir (string dir, vector<string> &files)
{
DIR *dp;
struct stat _buf;
struct dirent *dirp;
if((dp = opendir(dir.c_str())) == NULL) {
cout << "Error(" << errno << ") opening " << dir << endl;
return errno;
}
while ((dirp = readdir(dp)) != NULL) {
if(stat(dirp->d_name, &_buf) != 0x4)
files.push_back(string(dirp->d_name));
}
closedir(dp);
return 0;
}
int main()
{
string dir = string(".");
vector<string> files = vector<string>();
getdir(dir,files);
for (unsigned int i = 0;i < files.size();i++) {
cout << files[i] << endl;
}
return 0;
}

boost::filesystem::is_directory()
//I found it )
//So, also you can try to call stat() function. ( on Windows )
