Second, For anyone who is composing consumer accessors that aren't atomic it enables you to annotate for any upcoming consumer which the code is just not atomic when they are looking at its interface, without having making them implementation.
non-atomic variables, on the other hand, make no these guarantee but do offer you the luxurious of faster entry. To sum it up, select non-atomic whenever you know your variables won't be accessed by numerous threads at the same time and speed issues up.
I failed to would like to pollute world-wide namespace with 'id', so I put it to be a static while in the perform; however in that scenario you have to make sure that on your own platform that doesn't produce true initialization code.
