std::shared_lock::release

STD：：共享[医]锁：：释放

mutex_type* release(​(since C++14)

如果存在，则破坏关联互斥体的关联，以及*this...

锁都没锁。如果*this在调用之前，调用方拥有相关互斥锁的所有权，调用方现在负责解锁互斥锁。

参数

%280%29

返回值

指向关联互斥对象的指针或NULL如果没有相关的互斥。

例外

noexcept规格：

noexcept

例

另见

unlockunlocks the associated mutex (public member function)
releasedisassociates the associated mutex without unlocking it (public member function of std::unique_lock)
