If I understand your question correctly, one way to avoid having to 'post-process' is to move the pointer passed to ReadFile to the end of the available data, so the ReadFile call is appending to the buffer, instead of overwriting.
As Hans Passant and dauphic pointed, it doesn't seem to be a general solution for my question. I am writing, though, the code that I was trying to avoid, just in case somebody finds it useful or face the same problem that I had.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
