std::timed_mutex包含在<mutex>头文件中。 用法和std::mutex类似。 try_lock_for():等待一段时间,如果拿到了锁,或者超时了未拿到锁,就继续执行(有选择执行)如下 1std::chrono::milliseconds timeout(100);2if(my_mymutex.try_lock_for(timeout)){3//...拿到锁返回ture4}5else{6std::chrono::millisecon...

std::timed_mutex 在标头<mutex>定义 classtimed_mutex; (C++11 起) 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。 以类似mutex的行为,timed_mutex提供独占非递归所有权语义。另外,timed_mutex通过try_lock_for()和try_lock_until()方法,提供尝试带时限地要求timed_mutex所有权的能力。

std::timed_mutex::lock voidlock(); (C++11 起) 锁定互斥体。若另一线程已锁定此互斥体,则对lock的调用将阻塞执行,直至获得锁。 若为已占有此mutex的线程调用lock,则行为未定义:例如,程序可能死锁。鼓励能检测非法使用的实现抛出以resource_deadlock_would_occur为错误条件的std::system_error,而不是死锁。
