[問題] typedef在不同平台上編譯產生的錯誤
開發平台(Platform): (Ex: VC++, GCC, Linux, ...)
VC++ 6
額外使用到的函數庫(Library Used): (Ex: OpenGL, ...)
問題(Question)：
c檔的函式內容
/* show the all packet information in queue */
int show_q(LinkQueue *Q)
{
int seq_q = 1;
printf("// Show the packet information in queue //\n");
Queue *p = (Queue *)malloc(sizeof(Queue));
p = Q->front->next;
while(p!=NULL)
{
printf("(%d) sequence number: %2d, packet size: %d, arrival time: %d\n", seq_q, p->packet.sn, p->packet.pkt_size, p->packet.arr_time);
//system("PAUSE");
p = p->next;
seq_q++;
}
free(p);
return 1;
}
h檔的內容
typedef struct QNode {
PktStr packet;
struct QNode *next;
}Queue;
餵入的資料(Input)：
預期的正確結果(Expected Output)：
原先在Dev C執行正確，不過放到VC++ 6就出現以下錯誤訊息
錯誤結果(Wrong Output)：
