std::recursive_timed_mutex 在标头<mutex>定义 classrecursive_timed_mutex; (C++11 起) 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_...

std::recursive_timed_mutex::try_lock std::recursive_timed_mutex::try_lock bool try_lock(); (since C++11) 试图锁定互斥体。马上回来。关于成功锁定获取返回true,否则返回false... 此函数允许伪造失败并返回。false即使互斥锁目前没有被任何其他线程锁定。 线程可以调用try_lock在递归互斥体上重复。
std::recursive_timed_mutex::lockC++ Thread support library std::recursive_timed_mutex void lock(); (since C++11) Locks the mutex. If another thread has already locked the mutex, a call to lock will block execution until the lock is acquired. ...
