HRESULT GetDeviceCaps(
  UINT Adapter,
  D3DDEVTYPE DeviceType,
  D3DCAPS8* pCaps
);

Parameters

Adapter

[in] Ordinal number that denotes the display adapter. D3DADAPTER_DEFAULT is always the primary display adapter.

DeviceType

[in] Member of the D3DDEVTYPE enumerated type. Denotes the device type.

pCaps

[out] Pointer to a D3DCAPS8 structure to be filled with information describing the capabilities of the device.

Return Values

If the method succeeds, the return value is D3D_OK.

If the method fails, the return value can be one of the following values.

Remarks

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 IDirect3D8::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 D3DCAPS8.
