recursive_timed_mutex是一种同步原语,能用于保护共享数据免受从多个线程同时访问。 以类似std::recursive_mutex的方式,recursive_timed_mutex提供排他性递归所有权语义。另外,recursive_timed_mutex通过try_lock_for与try_lock_until方法,提供带时限地尝试要求recursive_timed_mutex所有权的能力。 recursive_timed_mutex类满足定时互斥体(TimedMutex)和标准布局类型(Stand...
classtimed_mutex; (since C++11) Thetimed_mutexclass is a synchronization primitive that can be used to protect shared data from being simultaneously accessed by multiple threads. In a manner similar tomutex,timed_mutexoffers exclusive, non-recursive ownership semantics. In addition,timed_mutexprovides...

timed_mutex::native_handle voidunlock(); (since C++11) Unlocks the mutex. The mutex must be locked by the current thread of execution, otherwise, the behavior is undefined. This operationsynchronizes-with(as defined instd::memory_order) any subsequent lock operation that obtains ownership of ...

shared_timed_mutex类是一种同步原语,能用于保护数据免受多个线程同时访问。与其他促进独占访问的互斥体类型相反,它拥有两个访问层次: 共享- 多个线程能共享同一互斥体的所有权。 独占- 仅一个线程能占有互斥体。 共享互斥体通常用于多个读线程能同时访问同一资源而不导致数据竞争,但只有一个写线程能访问的情形。
