OpenAdapter10 routine

The OpenAdapter10 function creates a graphics adapter object that is referenced in subsequent calls.

Syntax


PFND3D10DDI_OPENADAPTER OpenAdapter10;

HRESULT APIENTRY OpenAdapter10(
  _Inout_ D3D10DDIARG_OPENADAPTER *pOpenData
)
{ ... }

Parameters

pOpenData [in, out]

A pointer to a D3D10DDIARG_OPENADAPTER structure. On input, this structure contains information that the driver can use. On output, the driver specifies information that the Microsoft Direct3D runtime can use.

Return value

OpenAdapter10 returns one of the following values:

Return codeDescription
S_OK

The graphics adapter object was successfully created.

E_OUTOFMEMORY

OpenAdapter10 could not allocate memory that was required for it to complete.

 

Remarks

The graphics adapter object that is created by the OpenAdapter10 function represents the underlying graphics hardware. Before the Direct3D runtime can create a display device by calling CreateDevice(D3D10), the user-mode display driver should call the pfnQueryAdapterInfoCb function to query for the graphics hardware capabilities from the display miniport driver.

The Direct3D runtime can open multiple graphics adapter objects from a single graphics adapter.
