C++ 6.0 profiler 测试function的执行时间

[使用command line mode作profile的方法]

[下載範例:HelloWorld]

1.首先開啟您的workspace:

2. 選擇Project -> Settings...

3. 點選Link，勾選Enable profiling. 按OK完成設定.

4. Select Build -> "Build" or "Rebuild All" to build your workspace

5. build完成後, 點選Build -> Profile... 會出下如下視窗:

6. 點選Function timing, 表示我們要看每個function執行所花的時間

7. 按OK便關閉視窗，且開始作profiling的動作。

8. Profiling完成後便會在下面的訊息視窗列出Profile的結果:
