[問題] RDTSC用法?
<第一次PO文還請見諒>
我有爬了一下關於RDTSC的用法
但是自己寫了以後還是發生了一些問題
還請高手幫幫忙
以下是精簡程式
#include <cycle.h>
int main()
{
double t_elapsed=0.0;
ticks t0=getticks();
...........
程式區段
...........
ticks t1=getticks();
t_elapsed=elapsed(t1,t0);
cout << "T=" << t_elapsed << endl;
getch();
return 0;
}
compile後出現慘烈結果:
1. ticks,t1,t0 --> 尚未定義
2. ticks t0, ticks t1 --> statement missing
3. t_elapsed=elapsed(t1,t0) --> call to undefined function 'elpsed'
本身又是程式新手，還請大家能指導一下
另外，cout的變數(t_elapsed)應該沒有錯吧...?
謝謝!
