Der Parameter ist nicht empfohlen, sondern zwingend notwendig.
Der fehlende Parameter kann (wird) irgend wann zu einem
unauffindbaren Softwarefehler (Absturz) führen.

Es ist so, wie es Stargate gesagt hat.

Code: Alles auswählen

Global global1.i, global2.i
Procedure Thread1(dummy.i)
  Repeat
    global1 + 1
  Until global1 = 10
EndProcedure

Procedure Thread2(dummy.i)
  Repeat
    global2 + 1
  Until global2 = 15
EndProcedure

thread1.i = CreateThread(@Thread1(), 0)
thread2.i = CreateThread(@Thread2(), 0)

WaitThread(thread1)
WaitThread(thread2)

MessageRequester("out", "Should be 10: " + Str(global1) + " Should be 15: " + Str(global2))

(Ist jetzt mal so dahin gecodet)

Irgendwie funktioniert das nicht...
Mir ist es nicht gelungen den Fehler in einem "einfachen" Code zu reproduzieren. Also hier mal mein Programm:

Es ist ein Maus + Tastatur Recorder einzelne Recorder Arten funktionieren aber sobald 2 oder 3 Arten ausgewählt sind wird das Programm sofort beendet.

Threadsafe aktiviert?

Waere aber doof wenn dem wirklich so waere

Rueckgabewerte kann man mit GetExitCodeThread_ erhalten.

danke, Threadsafe wars

Cool, und wie geht das unter Linux und Mac?

Das ist eine gute Frage, vor allem für Mac

sucht mal nach pthread_join.
