IDirect3D9::GetDeviceCaps method
Retrieves device-specific information about a device.
Syntax
HRESULT GetDeviceCaps( [in] UINT Adapter, [in] D3DDEVTYPE DeviceType, [out] D3DCAPS9 *pCaps );
Parameters
- Adapter [in]
-
Type: UINT
Ordinal number that denotes the display adapter. D3DADAPTER_DEFAULT is always the primary display adapter.
- DeviceType [in]
-
Type: D3DDEVTYPE
Member of the D3DDEVTYPE enumerated type. Denotes the device type.
- pCaps [out]
-
Type: D3DCAPS9*
Pointer to a D3DCAPS9 structure to be filled with information describing the capabilities of the device.
Return value
Type: HRESULT
If the method succeeds, the return value is D3D_OK. If the method fails, the return value can be one of the following: D3DERR_INVALIDCALL, D3DERR_INVALIDDEVICE, D3DERR_OUTOFVIDEOMEMORY, and D3DERR_NOTAVAILABLE.
Remarks
The application should not assume the persistence of vertex processing capabilities across Direct3D device objects. The particular capabilities that a physical device exposes may depend on parameters supplied to 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.
