T load( std::memory_order order = std::memory_order_seq_cst ) const; | | |
T load( std::memory_order order = std::memory_order_seq_cst ) const volatile; | | |
原子加载并返回原子变量的当前值。的值影响内存。order...
order一定是std::memory_order_relaxed，，，std::memory_order_consume，，，std::memory_order_acquire或std::memory_order_seq_cst否则，行为是未定义的。
参数
order | - | memory order constraints to enforce |

返回值
原子变量的当前值。
