| void store( T desired, memory_order = std::memory_order_seq_cst ) volatile; | ||
Atomically replaces the current value with desired. Memory is affected according to the value of memory_order.
memory_order must be one of std::memory_order_relaxed, std::memory_order_release or std::memory_order_seq_cst. Otherwise the behavior is undefined.
