c++ boost （递归）遍历目录

c++ 终于有办法跨平台访问文件系统了，虽然还是要借助boost。不多说，上代码

/** visitdir.cpp **/
#include <iostream>
#include <boost/filesystem.hpp>

using namespace boost::filesystem;
using namespace std;

void print_files(const path &full_path)
{
    if (exists(full_path))
    {
        directory_iterator item_begin(full_path);
        directory_iterator item_end;

        for (; item_begin != item_end; ++item_begin)
        {
            if (is_directory(*item_begin))
            {
                cout << item_begin->path().native() << "\t[dir]" << endl;
                print_files(item_begin->path());
            }
            else
            {
                cout << item_begin->path().native() << endl;
            }
        }
    }
}

int main(int argc, const char **argv)
{
    if (argc < )
    {
        cerr << "Usage: " << argv[] << " <path>" <<endl;
        return ;
    }

    path full_path(argv[]);
    print_files(full_path);
    return ;
}

编译：

g++ visitdir.cpp -o visitdir -lboost_filesystem -lboost_system
