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,time
cppreference.com 创建账户 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...

但是,要想学会使用 std::lock_guard 和 std::unique_lock ,必须先了解基本的 std::mutex。 头文件: #include <mutex> 在头文件当中提供了四种互斥量: std::mutex 与 std::timed_mutex 先从最基本的 std::mutex 入手,其余互斥量皆是其变种。需要了解4个公共方法: ...
代码例子:(参考了 CPP Reference 当中例子) classBrainBox{public:std::mutexc_mutex;intvalue=0;};voidChangeValue(BrainBox&skylake,BrainBox&coffeelake){std::unique_lock<std::mutex>locker1(skylake.c_mutex,std::defer_lock);std::unique_lock<std::mutex>locker2(coffeelake.c_mutex,std::defer_lock)...
std::timed_mutex::unlock void unlock(); (since C++11) 打开互斥锁。 互斥锁必须由当前的执行线程锁定,否则,行为是未定义的。 这次行动同步性中定义的28名ASstd::memory_order%29获得相同互斥对象所有权的任何后续锁操作。 参数 %280%29 返回值...
