'atomic' implies it can't be damaged down. In OS/programming conditions an atomic function get in touch with is one particular that can not be interrupted - your complete function should be executed, and never swapped out with the CPU with the OS's usual context switching right up until It can be entire.
– tc. Commented Dec 1, 2010 at 18:20 @fyolnish I'm unsure what _val/val are, but no, probably not. The getter for an atomic duplicate/keep assets requirements making sure that it doesn't return an item whose refcount results in being zero due the setter becoming named in A different thread, which effectively indicates it must go through the ivar, retain it although making certain the setter hasn't overwritten-and-launched it, after which you can autorelease it to equilibrium the retain.

So so as to implement the above 3 Directions in an atomic trend, we must always to start with get exclusive entry to the cacheline which includes the essential price. At the time we get special obtain, we should not relinquish exclusive access on this cacheline until the "shop" operation is completed.
The last two are equivalent; "atomic" may be the default actions (Be aware that it's not actually a key word; it is specified only with the absence of nonatomic -- atomic was added being a keyword in latest variations of llvm/clang).

A lot of the atom is empty space. The remainder is made of a few standard types of subatomic particles: protons, neutrons, and electrons. The protons and neutrons form the atom’s central nucleus. (The ordinary hydrogen atom can be an exception; it incorporates just one proton but no neutrons.) As their names advise, protons Have a very optimistic electrical charge, though neutrons are electrically neutral—they carry no charge; overall, then, the nucleus contains a constructive charge.
