reference_wrapper通过使用std::ref显式初始化线程:auto thread1 = std::thread(SimpleThread, std::ref(a));(或std::cref代替std::ref,视情况而定)。根据cppreference中的std:thread注释:线程函数的参数按值移动或复制。如果需要将引用参数传递给线程函数,则必须将其包装(例如,使用std::ref或std::cref)。
代码例子:(参考了 CPP Reference 当中例子) classBrainBox{public: std::mutex c_mutex;intvalue = 3; };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,...
