Recursive_directory_iterator exception thrown

I am using the recursive_directory_iterator boost iterator to recursively scan through a directory. However, when an iterator runs in a directory for which my application does not have access, an exception of the type "boost :: filesystem3 :: filesystem_error" is thrown, which stops the iterator, and the program is interrupted. In any case, I can instruct the iterator to skip such directories.

I tried the code suggested in Moving a directory with boost :: with no exceptions , however, this did not work for me. I am using boost version 1.49.

My code after executing this sentence (the best I could think of) is as follows:

void scand()
{
    boost::system::error_code ec, no_err;

    // Read dir contents recurs
    for (recursive_directory_iterator end, _path("/tmp", ec);
         _path != end; _path.increment(ec)) {

        if (ec != no_err) {
            _path.pop();
            continue;
        }
        cout << _path->path() << endl;
    }
}

Thank you, Achmed.

boost:: filesystem (V3): https://svn.boost.org/trac/boost/ticket/4494. V2 (, std::tr2::filesystem). - .

boost::system::error_code ec;

    HandleFile(dit->path()); // <-- do something with the file
    ++dit;
  }
