Dear advanced boost/c/g++ programers:

  I copied and try a simple (Reading a directory with boost) program , from page 383, Example 10-19, of book(C++ cookbook)
----------you can download the code to try by yourself at, http://examples.oreilly.com/9780596007614/
// Example 10-19.  Reading a directory
#include <iostream>
#include <cstdlib>
#include <boost/filesystem/operations.hpp>
#include <boost/filesystem/fstream.hpp>

using namespace boost::filesystem;

int main(int argc, char** argv) {

   if (argc < 2) {
      std::cerr << "Usage: " << argv[0] << " [dir name]\n";
      return(EXIT_FAILURE);
   }

   path fullPath =      // Create the full, absolute path name
     system_complete(path(argv[1]));

   if (!exists(fullPath)) {
      std::cerr << "Error: the directory " << fullPath.string()
                << " does not exist.\n";
      return(EXIT_FAILURE);
   }

   if (!is_directory(fullPath)) {
      std::cout << fullPath.string() << " is not a directory!\n";
      return(EXIT_SUCCESS);
   }

   directory_iterator end;
   for (directory_iterator it(fullPath);
        it != end; ++it) {          // Iterate through each
                                    // element in the dir,
      std::cout << it->leaf();      // almost as you would
      if (is_directory(*it))        // an STL container
         std::cout << " (dir)";
         std::cout << '\n';
      }

      return(EXIT_SUCCESS);
}
