std::recursive_mutex

STD：：递归[医]互斥

Defined in header ​​
class recursive_mutex;​(since C++11)

大recursive_mutex类是一个同步原语，可用于保护共享数据不被多个线程同时访问。

recursive_mutex提供独占的递归所有权语义：

  • 调用线程拥有阿recursive_mutex当它成功地调用lock或try_lock.在此期间，线程可能会对lock或try_lock当线程进行匹配次数的调用时，所有权周期结束。unlock...

  • 当线程拥有recursive_mutex的调用，所有其他线程都将阻塞%28lock%29或收到false返回值%28try_lock%29如果他们试图声称对recursive_mutex...

  • 对象的最大次数。recursive_mutex可能被锁定是未指定的，但在达到该号码后，调用lock会扔std::system_error并呼吁try_lock会回来false...

如果recursive_mutex在某些线程仍然拥有的情况下被销毁。大recursive_mutex类满足Mutex和StandardLayoutType...

锁紧

锁锁互斥锁，如果互斥锁不可用，则阻塞%28公共成员函数%29。

试一试[医]锁试图锁定互斥锁，如果互斥锁不可用，则返回%28公共成员函数%29。

解锁解锁互斥锁%28公共成员函数%29

本机手柄

土生土长[医]句柄返回底层实现定义的线程句柄%28公共成员函数%29
