Playing with VS2012's preliminary implementation of <filesystem> before work on tr2 was halted.

filesystem_test.cpp

#include <iostream>
#include <string>
#include <filesystem>
#include <vector>
#include <algorithm>
#include <exception>

using namespace std;
using namespace std::tr2::sys;

int main()
{
	auto root = path("c:/");
	vector<directory_entry> dir_list;

	// Just to be sure ...
	if (!is_directory(root)) {
		cerr << "Directory \"" << root << "\" not found." << endl;
		throw runtime_error("Damn.");
	}

	// Populate our vector with all child directories.
	copy_if(directory_iterator(root), directory_iterator(), back_inserter(dir_list), [](directory_entry child) {
		return is_directory(child.status());
	});

	// Print our list of subdirectories.
	for (auto dir : dir_list)
	{
		cout << dir.path() << endl;
	}
}
