[問題] function定義後接著struct/int ?
如題，在寫網路模擬的作業，助教給的code
是.c 檔 compile下去一大桶error
但是我有看過程式開頭的註解 確定這個檔不是要學生填空的
而且還警告學生不可以改這個檔的內容...
裡面有很多error是來自於這種函式定義
void InsertEvent(p)
struct event *p;
{
// blah blah blah
} /* END OF InsertEvent */
void stoptimer(AorB)
int AorB; /* A or B is trying to stop timer */
{
//blah blah blah
}
請問 這是什麼語法...我完全沒有印象有看過這種函式定義和{}中間夾著東西
的寫法 .. (constructor除外..)QQ

void InsertEvent(p)
struct event *p;
{
// blah blah blah
} /* END OF InsertEvent */
==
void InsertEvent(struct event *p)
{
// blah blah blah
} /* END OF InsertEvent */
void stoptimer(AorB)
int AorB; /* A or B is trying to stop timer */
{
//blah blah blah
}
==
void stoptimer(int AorB)
{
//blah blah blah
}
請問是這個意思嗎@@
