[Boost-users] [Filesystem] File Rename issue

Hi,

       I have some trouble with a file renaming program i wrote. The program 
is supposed to recursively traverse a folders in search for a file, and 
rename the file to the name of the folder. The program, traverses all the 
folders successfully, but when i try the rename command i get the following 
compile error
"error C2039: current_path is not a member of 'path', see declaration of 
path. c:\boost\include\boost-1_33_1\boost\filesystem\path.hpp

I am aware that the current_path() function is not included in path.hpp 
however the object that i am trying to use it on is a directory _iterator 
and as such should work.
I am new to all of this stuff, any advice would be appreciated,

Below is the very non elegant source code with the problem highlighted close 
to the end of the code.

int i=0;
namespace fs = boost::filesystem;
bool recursiveList(fs::path);

int main()
{
        fs::path fullPath("test2");

        recursiveList(fullPath);
        std::cout<<"Number of files = "<<i<<"\n";

  return 0;
}

bool recursiveList(fs::path givenPath)
{
        char iteration=0;
        std::string directoryName="failed";
        fs::directory_iterator end_iter;
        fs::directory_iterator start_iter(givenPath);
        fs::directory_iterator restart_Path(givenPath);
        int numberOfFiles=0;
        givenPath=fs::system_complete(givenPath);
        std::cout<<"The full path is: 
"<<givenPath.native_directory_string()<<"\n\n";

        for (; start_iter!=end_iter; ++start_iter)
        {
                if ( fs::is_directory(*start_iter))
                {
                        std::cout<<start_iter->leaf()<<"[directory]\n\n";
                        directoryName=start_iter->leaf();
                        recursiveList(*start_iter);
                ;
                }
                else
                {
                        std::cout<<start_iter->leaf()<<"[file]\n\n";
                        i++;
                        numberOfFiles++;
                }

        }

        for (int j=0;j<numberOfFiles;j++,restart_Path++)
        {
                if(!fs::is_directory(*restart_Path))
                {
                        if (numberOfFiles==1)
                        {
                                std::cout<<"Multiple Files detected, attempting rename with 
iterations\n";
                                std::cout<<"Attempting Name Change...\n";
                                std::cout<<"Present Name: "<<restart_Path->leaf()<<"\n";
                                std::cout<<directoryName;

                                //PROBLEM HERE!!!!!
                                //*****************************************************
                                fs::rename(restart_Path->current_path(),directoryName);
                                //*****************************************************
                        }

                }
        }

        return true;
}
