An illustration: an internet poll, open-finished queries, but we want to sum up how many people provide the identical solution. There is a database table in which you insert answers and counts of that remedy. The code is simple:
So I'd be guessing that atomic In such a case signifies the attribute reader strategies can not be interrupted - in result meaning the variable(s) being examine by the method are unable to modify their benefit fifty percent way as a result of since A few other thread/phone/function will get swapped on to the CPU.
A load operation with this particular memory buy performs the purchase Procedure over the affected memory place: no reads or writes in The present thread might be reordered right before this load. All writes in Atomic Wallet other threads that launch the same atomic variable are visible in the current thread.
