Re: FFI - ``cstring`` or ``array[256,char]``?

I am checking in the [source 
code]([https://github.com/luvit/zlib/blob/master/contrib/minizip/unzip.c#L968)](https://github.com/luvit/zlib/blob/master/contrib/minizip/unzip.c#L968\)),
 and it defines:
    
    
    if ((err==UNZ_OK) && (szFileName!=NULL))
    {
     ....
    }
    
    Run

Not sure if this might the problem.
