linux 下opendir readdir 在windows下的替代函数

转自：http://blog.csdn.net/killerzhou/article/details/2301359

最近在做一个linux下c程序到windows下的移植工程，在移植过程中发现windows下对opendir readdir存在很大问题，经多方查找，终于在http://www.tenouk.com/cpluscodesnippet/viewtopic.php?t=670上找到了解决办法，利用_chdir,_findfist,_findnext函数，很轻松的完成了移植工作。

现把上面链接的程序贴过来，

To show: Using _chdir(), ctime()/ctime_s(), _findfirst(), _findnext(), _findclose() 

Code:

/* The use of the 32-bit _find functions to print a list     of all files (and their attributes) in the current directory. */  /* Don't forget to put the .h extension to the header files */  #include   #include   #include   #include   #include   #include   #include   #define SIZE 50  int main()  {     // char   path[50] = "C://WINNT//System32//config"; - Windows 2000     char   path[50] = "C://Windows//System32//config";     struct _finddata_t c_file;     intptr_t   hFile;     char buf[SIZE];     printf("Change to %s/n", path);     if(_chdir(path))     {        printf("Unable to locate the directory: %s/n", path);        exit(1);     }     else        /* Find first in the current directory */        hFile = _findfirst("*.*", &c_file);     /* List the files... */     printf("Listing of files in the directory %s/n/n", path);     printf("/nRDO HID SYS ARC  FILE                            DATE %20c SIZE/n", ' ');     printf("--- --- --- ---  ----                             ---- %20c ----/n", ' ');     printf((c_file.attrib & _A_RDONLY) ? " Y  " : " N  ");     printf((c_file.attrib & _A_SYSTEM) ? " Y  " : " N  ");     printf((c_file.attrib & _A_HIDDEN) ? " Y  " : " N  ");     printf((c_file.attrib & _A_ARCH)   ? " Y  " : " N  ");     // unsafe version is ctime()     ctime_s(buf, SIZE, &(c_file.time_write));     printf(" %-30s %.20s  %9ld/n", c_file.name, buf, c_file.size);     /* Find the rest of the files */     while(_findnext(hFile, &c_file) == 0)     {        printf((c_file.attrib & _A_RDONLY) ? " Y  " : " N  ");        printf((c_file.attrib & _A_SYSTEM) ? " Y  " : " N  ");        printf((c_file.attrib & _A_HIDDEN) ? " Y  " : " N  ");     printf((c_file.attrib & _A_ARCH)   ? " Y  " : " N  ");     // unsafe version is ctime()     ctime_s(buf, SIZE, &(c_file.time_write));     printf(" %-30s %.20s  %9ld/n", c_file.name, buf, c_file.size);     }     _findclose(hFile);     return 0;  }
