Question

我正在设计一个用c / c ++编写的快速文件读取程序，它将按照存储（创建）的顺序检索目录中的每个文件。我使用SFML和BOOST但我的程序只会以随机顺序返回文件。我想这与文件的b树排序有关？如何让BOOST按照创建顺序返回文件？

以下是代码的相关部分：

#include <string>
#include <iostream>
#include <boost/filesystem.hpp>
#include "SFML/Graphics.hpp"
using std::cout;
using namespace boost::filesystem;
using namespace std;
....
path p (argv[1]);
....
for (directory_entry& x : directory_iterator(p)){
  ....
  fullPathName = x.path().string();
  filename = x.path().filename().string();
  stem = x.path().stem().string();  
  seqnum = stem.substr(4,5);
  extn = x.path().extension().string();

  cout << fullPathName << ", " << filename << ", " << stem << ", " <<
    seqnum << ", " << extn <<'\n'; 
}

以下是示例输出：

../ take / test / snap00179.png，snap00179.png，snap00179,00179，.png ../takes/test/snap00321.png,buttle00321.png,but00001,00321,.png ../takes/test/snap00094.png,butt00094.png,butt00094,00094,.png ../takes/test/snap00121.png,hut00121.png,click00121, 00121,.png ../takes/test/snap00026.png,butk00026.png,butk00026,00026,.png ../takes/test/snap00024.png,butt00024.png,butt00024,00024,.png ../takes/test/snap00155.png,hock00155.png,buttle00155,00155,.png ../takes/test/snap00065.png,butk00065.png,butc00065,00065,.png ../takes/test/snap00015.png,butt00015.png,butt00015,00015,.png ../takes/test/snap00075.png,buttle00075.png,butc00075,00075,.png ../takes/test/snap00017.png,butk00017.png,butk00017,00017,.png

想要按创建顺序检索文件
