std::chrono::milliseconds dura(2); std::this_thread::sleep_for(dura); sleep_for是[5]this_thread命名空间下的独立函数,表示要求当前线程休眠指定的时间,这样可以避免占用过多资源。 二、构造函数初始化线程对象的2种方式 以下讨论是指线程对象std::thread对象关联了某执行线程,没有关联的,不再考虑范围之内...

构造函数传入的是年月日时分秒,以及毫秒。构造函数如下: EpochTime(intyy,intmm,intdd,inthh,intmi,intss,intms):ymd_(year_month_day{year(yy)/mm/dd}),hms_(hh_mm_ss<milliseconds>(milliseconds(1000*(hh*3600+mi*60+ss)+ms))){} 因为std::chrono重载了运算符/,因此可以在ymd_初始化时使用year...
