hi,

I'm looking for an open source library similar to picostorage, who can recommend a few?

I've been using picostorage,but recently i found that the File is very easy to damage. so i want to look for an open source library.

If the file is damaged,I can not get the data and I do not know the file has been damaged.

These two functions is my functions to manipulate files.

My operating system is window7.

static void __store_data_of( IN ps::Dir &rootdir, IN std::string const &key, IN std::string const &data )
{
    if ( key == "" )
    {
        //  invalid key name, just return
        return;
    }

    ps::File file = rootdir.openFile( key.c_str() );
    if ( !file )
    {
        file = rootdir.createFile( key.c_str() );
        if ( !file )
        {
            thrd_core_dump_tm( __FUNCTION__", faile to createFile\n");
            return;
        }
    }
    file.setSize( data.size() );
    file.pwrite( data.c_str(), data.size(), 0 );
    file.commit();
}

static bool __fetch_data_of( IN ps::Dir &rootdir, IN std::string const &key, OUT std::string &data )
{
    if ( key == "" )
    {
        //  invalid key name, just return
        return  false;
    }

    ps::File file = rootdir.openFile( key.c_str() );
    if ( !file || !file.getSize() )
    {
        return  false;
    }

    size_t  len = (size_t)file.getSize();

    char *_data = (char*)malloc( len + 1);

    LOKI_ON_BLOCK_EXIT( &::free, _data );

    memset( _data, 0, len + 1 );

    file.pread( _data, len, 0 );

    data = std::string( _data, len );

    return  true;
}
