std::recursive_mutex::unlock

STD：：递归[医]互斥：：解锁

void unlock(​(since C++11)

如果互斥锁的所有权级别为1%28准确地说，还有一个呼叫lock()比有人打电话到unlock()由此线程%29生成，否则会降低1的所有权级别。

互斥锁必须由当前的执行线程锁定，否则，行为是未定义的。

这次行动同步性中定义的28名ASstd::memory_order%29获得相同互斥对象所有权的任何后续锁操作。

参数

%280%29

返回值

%280%29

例外

%280%29

注记

unlock()通常不直接调用：std::unique_lock和std::lock_guard用于管理独占锁定。

例

另见

locklocks the mutex, blocks if the mutex is not available (public member function)
try_locktries to lock the mutex, returns if the mutex is not available (public member function)
