But a more in-depth seem reveals this nucleus comprises protons and neutrons, which might be designed up of particles termed quarks and gluons. Atoms of various things have unique figures of protons, neutrons and electrons.

edit: If your x86 implementation is magic formula, I would be joyful to hear how any processor relatives implements it.

You must first erase (dealloc) it and You'll be able to generate on to it. If in the meanwhile that the erase is done (or 50 % accomplished) and practically nothing has but been wrote (or half wrote) and you seek to read through it could be pretty problematic!
