推 darkflier:簡單的講就是 他只檢查成功 不是成功就是失敗 10/26 23:14
→ func:隻是幾個macro而已，用不用無所謂，標準的做法是用。你可以看 10/27 00:08
→ func:看macro的代碼。 10/27 00:08
→ moonjustin:謝謝，我後來去查DirectX SDK也是建議使用Macro 10/30 09:03
DirectX的函式都會告訴我們類似
只要回傳D3D_OK就表示成功，
感覺上是要讓我們把回傳值和 D3D_OK作比較即可
但是我看到網路上一篇文章這樣寫：
Virtually all methods in DirectX return an HRESULT for success/failure.
The proper way to test if the method failed is with the FAILED macro.
There is also a SUCCEEDED macro to test for success.
In many examples, success will be tested by comparing the HRESULT with D3D_OK.
This is not the proper way to do it.
They only guaranteed method of testing for failure is with the supplied macros.
不知道這樣代表什麼意思？
