Am I doing this right? (File byChunk)

What do those have to do with each other?

It doesn't seem right to me either, because you are allocating memory in 
chunks and passing it to C without keeping pointers around. Also what does 
that function do with them? If it keeps them around, you might be faster 
to load the whole file in one go and make a single call (fewer allocations, 
fewer calls, no-extra memory usage, etc.)
