定义于头文件 <mutex>
class recursive_timed_mutex;		(C++11 起)

recursive_timed_mutex 类是一个同步原语，可用于保护共享数据免受多个线程同时访问。

与 std::recursive_mutex 类似，recursive_timed_mutex 提供独占的、递归的所有权语义。此外，recursive_timed_mutex 还可以通过成员函数 try_lock_for 和 try_lock_until 来尝试在超时时间内获取 recursive_timed_mutex 的所有权。

recursive_timed_mutex 类满足 TimedMutex 和 StandardLayoutType 的所有要求。

成员类型

成员类型	定义
native_handle_type (可选*)	实现定义

成员函数

(构造函数)	构造互斥体 (public member function)
(析构函数)	销毁互斥体 (public member function)
operator= [已删除]	不可复制赋值 (public member function)
加锁
lock	锁定互斥体，如果互斥体不可用则阻塞 (public member function)
try_lock	尝试锁定互斥体，如果互斥体不可用则返回 (public member function)
try_lock_for	尝试锁定互斥锁，如果互斥锁在指定超时时间内不可用，则返回 指定超时持续时间不可用 (public member function)
try_lock_until	尝试锁定互斥锁，如果互斥锁在指定超时时间内不可用，则返回 在指定时间点之前不可用 (public member function)
unlock	解锁互斥体 (public member function)
原生句柄
native_handle	返回底层实现定义的原生句柄对象 (public member function)
