Is Yashied's Hotkey UDF really reentrant?

[Mbee]

If you look at the code of Yashied's HotKey UDF and read the description of the '$iFlags' parameter value "$HK_FLAG_NOOVERLAPCALL", it says that if you pass this flag to '_HotKey_Assign()', it "Prevents a call the user function if it has not complete. ..."  This clearly implies that if you do NOT use this flag value, the user function will be invoked again even if that function is still working on the previous invocation.  This in turn seems to imply that the Hotkey UDF allows reentrant coding/processing, which I had thought was not possible for AutoIt code.

If my reasoning regarding these implications is correct, I would be extremely pleased!  But I'm having trouble believing those implications - it really does seem impossible for AutoIt.  So my question is: does Yashied's Hokey UDF truly provide reentrance?

If not, is there any straightforward way to implement this ability without running two simultaneous scripts that communicate with each other?  My needs are too minor to bother with such a complex project...

Thanks!

If you use hotkeyset you'll notice you can call a function at any time.

Never used that UDF but yes, it seems like the flag you talk about is a check to make sure the function completed it's task.

; $HK_FLAG_NOOVERLAPCALL
; Prevents a call the user function if it has not complete. This flag is primarily to be set if the user function uses the MsgBox() and similar to it.
; Remember that your specified function is an interrupt function to the program and should not suspend the program or the program may hang. However,
; it is not recommended to use the MsgBox() inside your function, it is better to define the control flag which will test the main program loop.
; Only the _HotKey_Assign() function uses this flag.

I do not read this as the UDF allowing reentrant coding but that the results of calling the function multiple times while it is still running might be undefined or even hang your script. That's why $HK_FLAG_NOOVERLAPCALL is th default.
