This is what I was afraid of ;-)
You can't map a managed struct/class to a buffer (probably a byte array) to
without copying ( part of) the buffer to an instance of that struct/class.
So I'm not clear as to what you mean with "What I do is to load the complete
file in memory, then maps a structure to...", does this mean you are DOING
this, or that you would LIKE to DO...
