Std::atomic bool load
WebStores a value into the bool if the current value is the same as the current value.. The return value is always the previous value. If it is equal to current, then the value was updated.. … Web std:: atomic template struct atomic; Atomic Objects of atomic types contain a value of a particular type ( T ). The main characteristic of atomic objects is that access to this contained value from different threads cannot cause data races (i.e., doing that is well-defined behavior, with accesses properly sequenced).

WebJan 5, 2024 · The strange thing is that the stack trace has a problem with the std::atomic operation. Since the loggers use different instances, I don't see why it would stop crashing if I use only one logger. By the way, the GFC prefix is sometimes given to class names, is there any difference between a class without the GFC prefix?
