cocos2d-x 实现跨平台的目录遍历

可能各位看官们有更好的方法，请不吝赐教。

#ifdef _WIN32
#include <io.h>
#else
#include <unistd.h>
#include <stdio.h>
#include <dirent.h>
#include <sys/stat.h>
#endif

win32平台引用io.h里面的信息。

主要定义了一个void dfsFolder(string folderPath, int depth = 0);方法对其进行递归遍历。

具体的实现为

 1 void dfsFolder( string folderPath, int depth)
 2 {
 3 #ifdef WIN32
 4     _finddata_t FileInfo;
 5     string strfind = folderPath + "\\*";
 6     long Handle = _findfirst(strfind.c_str(), &FileInfo);
 7 
 8     if (Handle == -1L)
 9     {
10         cerr << "can not match the folder path" << endl;
11         exit(-1);
12     }
13     do{
14         //判断是否有子目录
15         if (FileInfo.attrib & _A_SUBDIR)    
16         {
17             //这个语句很重要
18             if( (strcmp(FileInfo.name,".") != 0 ) &&(strcmp(FileInfo.name,"..") != 0))   
19             {
20                 string newPath = folderPath + "\\" + FileInfo.name;
21                 dfsFolder(newPath);
22             }
23         }
24         else  
25         {
26             string filename = (folderPath + "\\" + FileInfo.name);
27 28             cout << folderPath << "\\" << FileInfo.name  << " " << endl;
29         }
30     }while (_findnext(Handle, &FileInfo) == 0);
31 
32     _findclose(Handle);
33 #else
34     DIR *dp;
35     struct dirent *entry;
36     struct stat statbuf;
37     if((dp = opendir(folderPath.c_str())) == NULL) {
38         fprintf(stderr,"cannot open directory: %s\n", folderPath.c_str());
39         return;
40     }
41     chdir(folderPath.c_str());
42     while((entry = readdir(dp)) != NULL) {
43         lstat(entry->d_name,&statbuf);
44         if(S_ISDIR(statbuf.st_mode)) {
45 
46             if(strcmp(".",entry->d_name) == 0 ||
47                 strcmp("..",entry->d_name) == 0)
48                 continue;
49             printf("%*s%s/\n",depth,"",entry->d_name);
50             dfsFolder(entry->d_name,depth+4);
51         } else {
52             string filename = entry->d_name;
53 54             printf("%*s%s\n",depth,"",entry->d_name);
55         }
56     }
57     chdir("..");
58     closedir(dp);
59 #endif
