Smart pointer classes can make this less burdensome. If you forget to free memory that you allocated, that's a memory leak and a bug. If you try to use memory after freeing it, or you try to free memory more than once, those are also nasty bugs. kvb salem main branchWebC++ 支持原子線程柵欄，即通過函數atomic_thread_fence保證使用std::atomic<>操作的線程的屬性的柵欄。 它需要一個記憶順序參數來調整圍欄的“強度”。 我知道當並非所有原子操作都以“強”順序完成時，圍欄很有用：. 當線程中並非所有原子讀取 (1) 都是獲取操作時，您可能會發現獲取柵欄的用途； jazarri sinonimoakWeb15 jun. 2016 · The C++ memory model consists of two aspects.
