Linux下延时两秒示例: usleep - sleep some number of microseconds 它微妙: curl "http://jackxiang.com/test/test3" usleep 2000000; curl "http://jackxiang.com/test/test3" usleep 2000000; curl "http://jackxiang.com/test/test3" usleep 2000000; curl "http://jackxiang.com/test/test3" Linux...
这就是如何使线程休眠不到一毫秒。在Unix上,您通常有许多选择(睡眠,睡眠和纳米睡眠)以满足您的需求。但是,在Windows上,只有Sleep具有毫秒级的粒度。 在Unix上,我可以使用 select 系统调用来创建一个非常简单的微秒睡眠: int usleep(long usec) { struct timeval tv; tv.tv_sec = usec/1000000L; tv.tv_usec ...
//Sleep(100); //auto tp6 = std::chrono::steady_clock::now(); //cout << "间隔时间微秒:" << std::chrono::duration_cast<std::chrono::microseconds>(tp6 - tp5).count() << "微秒" << endl; //cout << "间隔时间纳秒:" << std::chrono::duration_cast<std::chrono::nanoseconds>(...
NdisMSleep 函式會延遲以毫秒為單位的指定間隔執行呼叫端。 語法 C++ 複製 void NdisMSleep( [in] ULONG MicrosecondsToSleep ); 參數 [in] MicrosecondsToSleep 要延遲的微秒數。 傳回值 無 備註 對於MicrosecondsToSleep 參數中的指定時間,呼叫端的執行線程會進入等候狀態,進而讓其他線程在目前的處理器上完成工...

A serious real-time system implementor uses the terms milliseconds and microseconds to define specific time requirements. A millisecond (abbreviated ms) is 1/1000 (0.001) of a second. Examples of where programmers encounter milliseconds in the Win32 API include the Sleep and WaitForSingleObject functi...
