Non-blocking Sleep or suitable equivalent implementation?


Go to solution Solved by posixcompliant,

Recommended Posts

I'm looking to fire off several actions at certain, precise and staggered offsets from an initial point in time. So let's say that after precisely 17 seconds, the first function is fired. After 19 seconds, the second function is fired. After 21 seconds, the third function is fired. The problem is that each of these three staggered functions may block for a brief but indeterminate period of time, and I'm looking to delay each function relative to the starting time, as opposed to delaying each function relative to the completion of the preceding one. Is this kind of thing possible in AutoIt?

AdlibRegister() also could help.

you could use my >simple stopwatch udf.

here a possible way of use:

Stopwatch(3) ; reset counter to 0 and start counting

    ; call here your first function()
    ; if your function takes longer than 3 seconds to complete
    ; then it will delay the entire process of course

Do ; example of use do/until loop to wait

Until Stopwatch() >= 3000 ; stay here for 3 seconds (3000 ms) from previous stopwatch reset

ConsoleWrite(Stopwatch() & " ms elapsed" & @CRLF)

; ----------------------------------------------------

Stopwatch(3) ; reset counter to 0 and start counting

    ; call here your second function()
    ; if your function takes longer than 4 seconds to complete
    ; then it will delay the entire process of course

While Stopwatch() <= 4000; stay here for 4 seconds (4000 ms) from previous stopwatch reset

WEnd ; example of use while/Wend loop to wait

ConsoleWrite(Stopwatch() & " ms elapsed" & @CRLF)



; #FUNCTION# (snippet) ==========================================================================================================
; Name...........: Stopwatch
; Description ...: returns the number of milliseconds counted (according to actions requests by caller)
; Syntax.........: Stopwatch([$action])
; Parameters ....: $action: 0 - pause counting
;                           1 - resume counting
;                           2 - reset counter to 0 and stops
;                           3 - reset counter to 0 and start counting
;                           4 - (default) just ruturns actual counting value and status (status in @extended)
;
; Return values .: number of milliseconds in counter
;                  @extended contains paused status (1 or 0)
;                  1 if stopwatch is in pause
;                  0 if stopwatch is counting

Func Stopwatch($ToggleTo = 4)
    Static Local $Paused = True
    Static Local $Stopwatch = 0
    Static Local $TotalTime = 0
    Switch $ToggleTo
        Case 0 ; pause counter
            If $Paused Then
                SetExtended($Paused) ; $Paused status
                Return $TotalTime ; already paused, just return current $TotalTime
            Else
                $TotalTime += TimerDiff($Stopwatch)
                $Paused = True
                SetExtended($Paused)
                Return $TotalTime
            EndIf
        Case 1 ; unpause counter
            If $Paused Then
                $Stopwatch = TimerInit()
                $Paused = False
                SetExtended($Paused)
                Return $TotalTime
            Else
                SetExtended($Paused)
                Return $TotalTime + TimerDiff($Stopwatch)
            EndIf
        Case 2 ; reset to 0 and pause
            $Paused = True
            $TotalTime = 0
            SetExtended($Paused)
            Return $TotalTime
        Case 3 ; reset to 0 and restart
            $Paused = False
            $TotalTime = 0
            $Stopwatch = TimerInit()
            SetExtended($Paused)
            Return $TotalTime
        Case 4 ; return status
            SetExtended($Paused)
            If $Paused Then
                Return $TotalTime
            Else
                Return $TotalTime + TimerDiff($Stopwatch)
            EndIf
    EndSwitch
EndFunc   ;==>Stopwatch

EDIT:

moved the calling of your function outside the loops in listing

EDIT2:

after reading better the first post, I see that there is not need to use my stopwatch in this case, but the use of TimerInit() / TimerDiff() is sufficient.
anyway... it also works

small minds discuss people average minds discuss events great minds discuss ideas.... and use AutoIt....
