boost::filesystem::directory_ite

如下代码是用来获取src_dir的当前目录TopDirectoryOnly或者及其子目录AllDirectory下，满足后缀extension的文件。release下正常，debug下出现 Run-Time Check Failure #2 - Stack around the variable ‘xxx stat’ was corrupted.

解决方法:

使用boost_filesystem-vc100-mt-gd-1_49.lib 而不能用boost_filesystem-vc100-mt-gd-1_47.lib，PCL 1.6.0中两个都有。

void FileSystemHelper::get_directory_files(std::vector<std::string> &files_vec, 
    const std::string &src_dir, 
    const std::string extension/* = ".txt"*/, 
    search_option_t search_option /*= TopDirectoryOnly*/)
{
    boost::filesystem::path src_path(src_dir.c_str(), boost::filesystem::native);
    if(!boost::filesystem::exists(src_path)){
        return;
    }

    typedef boost::filesystem::directory_iterator d_iterator;
    if(boost::filesystem::is_directory(src_path)){
        d_iterator tmp_dir_end;
        d_iterator tmp_dir_iter(src_path);
        for(; tmp_dir_iter != tmp_dir_end; ++tmp_dir_iter){
            if(boost::filesystem::is_directory(*tmp_dir_iter)){
                if(AllDirectories == search_option){
                    get_directory_files(files_vec, tmp_dir_iter->path().string(), extension, search_option);
                }
            }else if(boost::filesystem::is_regular_file(*tmp_dir_iter)){
                if(0 == extension.compare(".")){
                    files_vec.push_back(tmp_dir_iter->path().string());
                }else{
                    if(is_file_end_with(tmp_dir_iter->path().string(), extension)){
                        files_vec.push_back(tmp_dir_iter->path().string());
                    }
                }
            }
        }
    }else{
        if(is_file_end_with(src_dir, extension)){
            files_vec.push_back(src_dir);
        }
    }
}
