基本作用跟std::this_thread::sleep_for是一样的 头文件定义:#include <boost/thread.hpp> 调用例子:boost::this_thread::sleep_for(boost::chrono::milliseconds(1000));//延时1秒 boost线程中表示睡眠的函数有sleep和sleep_for 头文件:#include <boost/thread.hpp> sleep 例如: boost::this_thread::sleep(...
特别地,将深入分析std::this_thread::sleep_for函数,揭示它如何与操作系统内核协作,实现线程的暂停执行,及其对系统资源的影响。 2. 从理论上看下这几个方法 sleep_for: 使当前线程休眠指定的时间段。 std::this_thread::sleep_for(std::chrono::milliseconds(100)); // 休眠100毫秒 sleep_until: 使当前...
for (int i = 0; i < 10000; i++) boost::this_thread::sleep_for(boost::chrono::milliseconds(1)); } int _tmain(int argc, _TCHAR* argv[]) { boost::thread_group tg; for (int i = 0; i < 30; i++) tg.create_thread(worker); tg.join_all(); cout << "All done!" << e...
所在可以在此断点,将 abs_time.milliseconds 改为 uint64(-1),就可以重现死锁了. 实际上该参数很可能输入为-1: wait_until(...) { do_wait(lock, ceil<milliseconds>(t-Clock::now()).count()); ... } 这几天改服务器代码,添加了许多 sleep_for(), 结果就经常发现服务器停止响应了。 幸好该错误...
std::this_thread::sleep_for(std::chrono::milliseconds(100)); 突然好奇,这个sleep_for和windows api的Sleep有什么区别? 右键,转到定义: 发现sleep_for是调用的sleep_until。里面又有一个_Thrd_sleep。又追。 进入xthreads.h,阿勒,这里只有声明没有定义呢。
this_thread::sleep_for(chrono::milliseconds(1000));//阻塞当前线程1000毫秒 this_thread::sleep_for(chrono::seconds(20)+ chrono::minutes(1));//阻塞当前线程1分钟20秒 this_thread::sleep_for(chrono::hours(1));//阻塞当前线程1小时 使用std::this_thread::sleeo_until()阻塞当前线程直到某个时间...

I was writing a slow-text output function that took use of C++ 11's `std::this_thread::sleep_for(std::chrono::milliseconds(delay));` I finished up the script and ran the command `g++ functions.cpp -std=c++11` and was greeted with this error message: ``` functions.cpp:29:14: err...
