模型内存顺序和原子操作顺序(1)

六个原子操作类型：memory_order_relaxed， memory_order_consume,memory_order_acquire, memory_order_release

对于acquire 和release， acquire 会等待release x.load 会失败，x.store 必然会先于x.load


void write_x_then_y()
{
Sleep(10000);


x.store(true, memory_order_release);


cout << "find" << endl;
}


void read_y_then_x()
{
while (!x.load(memory_order_acquire))
{
cout << "wait" << endl;
}


cout << "finish" << endl;
}
