IDirect3D9::GetDeviceCaps Method

Retrieves device-specific information about a device.

Syntax

HRESULT GetDeviceCaps(      

    UINT Adapter,
    D3DDEVTYPE DeviceType,
    D3DCAPS9 *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 D3DCAPS9 structure to be filled with information describing the capabilities of the device.

Return Value

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.

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 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.
