どちらの書き方がより一般的でしょうか？
//ソース１
if (FAILED(D3D->CreateDevice(
D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, HWnd,
D3DCREATE_MIXED_VERTEXPROCESSING,
&d3dpp, &Device))
)
if (FAILED(D3D->CreateDevice(
D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, HWnd,
D3DCREATE_HARDWARE_VERTEXPROCESSING,
&d3dpp, &Device))
)
if (FAILED(D3D->CreateDevice(
D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, HWnd,
D3DCREATE_SOFTWARE_VERTEXPROCESSING,
&d3dpp, &Device))
)
if (FAILED(D3D->CreateDevice(
D3DADAPTER_DEFAULT, D3DDEVTYPE_REF, HWnd,
D3DCREATE_SOFTWARE_VERTEXPROCESSING,
&d3dpp, &Device))
) return false;
//ソース２
if (FAILED(D3D->CreateDevice(D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, HWnd, D3DCREATE_MIXED_VERTEXPROCESSING, &d3dpp, &Device))
&& FAILED(D3D->CreateDevice(D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, HWnd, D3DCREATE_HARDWARE_VERTEXPROCESSING, &d3dpp, &Device))
&& FAILED(D3D->CreateDevice(D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, HWnd, D3DCREATE_SOFTWARE_VERTEXPROCESSING, &d3dpp, &Device))
&& FAILED(D3D->CreateDevice(D3DADAPTER_DEFAULT, D3DDEVTYPE_REF, HWnd, D3DCREATE_SOFTWARE_VERTEXPROCESSING, &d3dpp, &Device))
){
return false;
}
