[理工] [OS] system call

[jim055006 (好崩潰)]

 洪X老師的筆記裡面有說

void test()
{
  int*p;

  p=new(t);

  int a=5;

  scanf("%d",&a);

  a++;

  printf("%d",a);

  exit();
}


黃色的皆是system call
請問
(1) test()不是system call嗎??

(2) p=new(t)  scanf("%d",&a)    printf("%d",a)

    這三個分別是屬於那類的system call?

有請大心的高手解答
鋼溫!!!!

推 SiriusCloud:p = new (t) is process control
→ SiriusCloud:scanf printf are device management.
→ SiriusCloud:如果依照恐龍本分類的話...我是把scanf printf當I/O
→ SiriusCloud:wiki解釋:http://en.wikipedia.org/wiki/System_call
→ SiriusCloud:test()不是system call 是function
→ jim055006:我也是想說scanf跟printf是I/O的...
→ jim055006:那請問p=new(t)算是process control裡的create嗎?
推 SiriusCloud: y
→ jim055006:感謝S大!!!
