#### 14.2.7 Simple Program to List a Directory, Mark II

Here is a revised version of the directory lister found above (see Simple Directory Lister). Using the `scandir` function we can avoid the functions which work directly with the directory contents. After the call the returned entries are available for direct use.

         #include <stdio.h>
         #include <dirent.h>

         static int
         one (const struct dirent *unused)
         {
           return 1;
         }

         int
         main (void)
         {
           struct dirent **eps;
           int n;

           n = scandir ("./", &eps, one, alphasort);
           if (n >= 0)
             {
               int cnt;
               for (cnt = 0; cnt < n; ++cnt)
                 puts (eps[cnt]->d_name);
             }
           else
             perror ("Couldn't open the directory");

           return 0;
         }

Note the simple selector function in this example. Since we want to see all directory entries we always return `1`.
