I've take a look to boost::pool, tell me if I understand well.

Unfortunately, I never used it myself, so I'm afraid I can't enlighten you more than the library reference.

void MyMemoryObj::Write(long pData, long byte_to_write)
{
// In windows I write the data pointed to pData into the buffer with:
RtlMoveMemory pMem, pData, byte_to_write
}

Is there a way to copy memory in boost?

Why boost? It's just std::copy()

Or if you insist on working with plain C pointers, instead of c++ iterators, then use plain C memcpy()
