This command sleep will delay the output by seconds specified in sleep command. flush () may not be able to override the buffering scheme of your web server and it has no effect on any client-side buffering in the browser. We can create a delay by using sleep command inside our PHP script. This attempts to push current output all the way to the browser with a few caveats. somewhat shorter sleeps, and try TimePeriod:=3 or less to allow the shortest possible sleeps.ĭllCall("Winmm\timeBeginPeriod", "UInt", TimePeriod) Affects all applications, not just this script's DllCall("Sleep".), but does not affect SetTimer.ĭllCall("Sleep", "UInt", SleepDuration) Must use DllCall instead of the Sleep command.ĭllCall("Winmm\timeEndPeriod", "UInt", TimePeriod) Should be called to restore system to normal. Flushes the system write buffers of PHP and whatever backend PHP is using (CGI, a web server, etc). On a PC whose sleep duration normally rounds up to 15.6 ms, try TimePeriod:=7 to allow 2 is different than 3) depending on the value below. SleepDuration := 1 This can sometimes be finely adjusted (e.g. SetBatchLines -1 Ensures maximum effectiveness of this method. Note: While a script like this is running, the entire operating system and all applications are affected by timeBeginPeriod below. Here you can see it has couple of memcached connections. Using same netstat command and filtering on the PID we can find which connections does this process have. SetKeyDelay, SetMouseDelay, SetControlDelay, SetWinDelay, SetBatchLines Examplesĭemonstrates how to sleep for less time than the normal 10 or 15.6 milliseconds. tcp 0 0 192.168.1.70:35556 192.168.1.92:11211 ESTABLISHED 28540/php-cgi. This can be used to force any pending interruptions to occur at a specific place rather than somewhere more random. Sleep -1: A delay of -1 does not sleep but instead makes the script immediately check its message queue. While sleeping, new threads can be launched via hotkey, custom menu item, or timer. However, a Delay of 0 should always wind up being shorter than any longer Delay would have been. Thus, a delay of 0 produces an actual delay between 0 and 20 ms (or more), depending on the number of needy processes (if there are no needy processes, there will be no delay at all). This is because the OS gives each needy process a slice of CPU time (typically 20 milliseconds) before giving another timeslice to the script.Ī delay of 0 yields the remainder of the script's current timeslice to any other processes that need it (as long as they are not significantly lower in priority than the script). The actual delay time might wind up being longer than what was requested if the CPU is under load. To achieve a shorter delay, see Examples. For example, a delay between 1 and 10 (inclusive) is equivalent to 10 or 15.6 on most Windows 2000/XP systems. Remarksĭue to the granularity of the OS's time-keeping system, Delay is typically rounded up to the nearest multiple of 10 or 15.6 milliseconds (depending on the type of hardware and drivers installed). ![]() The amount of time to pause (in milliseconds) between 483647 (24 days), which can be an expression. Waits the specified amount of time before continuing. Sleep - Syntax & Usage | AutoHotkey v1 Sleep
