UINT Adapter, D3DDEVTYPE DeviceType, D3DCAPS9 *pCaps );
- [in] Ordinal number that denotes the display adapter. D3DADAPTER_DEFAULT is always the primary display adapter.

If the method succeeds, the return value is D3D_OK.
If the method fails, the return value can be one of the following values.
D3DERR_INVALIDCALL The method call is invalid. For example, a method's parameter may have an invalid value. D3DERR_INVALIDDEVICE The requested device type is not valid. D3DERR_OUTOFVIDEOMEMORY Direct3D does not have enough display memory to perform the operation.
The application should not assume the persistence of vertex processing capabilities across Microsoft?Direct3D?device objects. The particular capabilities that a physical device exposes may depend on parameters supplied to IDirect3D9::CreateDevice. For example, the capabilities may yield different vertex processing capabilities before and after creating a Direct3D Device Object with hardware vertex processing enabled. For more information see the description of D3DCAPS9.
