ProcessExists() documentation question

[rcmaehl]

Hi all,

Just wanted to verify something from the documentation for ProcessExists().

It notes that The process is polled approximately every 250 milliseconds.

Does this mean it can take up to 250ms for the function to realize a process exists or no longer exists? If so, does this limitation affect ProcessList() as well?
EDIT: In terms of how often the process list it checks against is updated, not the function execution time

Thanks in advance!

The documentation is obviously incorrect. It is only polled once per statement.

You can find out for yourself how long it takes by writing a simple test script. On my PC it is 7ms regardless of whether notepad is active or not.

 

$start = TimerInit()
For $i = 1 To 1000
$x =  ProcessExists("notepad.exe")
Next
ConsoleWrite("Per iteration = " & TimerDiff($start) / 1000 & " ms")

Was referring to how often the process list it checks against is updated, not the execution time of the function.
