This is how I list my directory in c

void ListDir(void)
{
  DIR *dir;
  struct dirent *ent;
  char dir_buffer [100];

  strcpy (dir_buffer, hard_drive ) ;

   
    if ((dir = opendir(dir_buffer)) == NULL)
        {
            printf ("\r\nUnable to open directory");
        }
    else
        {
            printf ("\r\nListing Directory %s", dir_buffer);
            while ((ent = readdir(dir)) != NULL)
                {
                    printf ("\r\n%s", ent->d_name);
                }
            if (closedir(dir) != 0)
                {
                    printf("\r\nUnable to close directory");
                }
        }

}
