Exempel

I följande exempel startas en instans av Anteckningar. Den hämtar sedan den fysiska minnesanvändningen för den associerade processen med 2 sekunders intervall i högst 10 sekunder. Exemplet identifierar om processen avslutas innan 10 sekunder har förflutit. Exemplet stänger processen om den fortfarande körs efter 10 sekunder.

Kommentarer

Metoden Close gör att processen slutar vänta på att avslutas om den väntade, stänger processhandtaget och rensar processspecifika egenskaper. Close stänger inte standardutdata, indata och felläsare och skrivare om de refereras externt.
