D3DDDI_ADAPTERCALLBACKS structure

Description

The D3DDDI_ADAPTERCALLBACKS structure contains pointers to Direct3D runtime callback functions that the user-mode display driver (UMD) can use.

Members

`pfnQueryAdapterInfoCb`

Pointer to the pfnQueryAdapterInfoCb function, which UMD uses to query the display miniport driver (KMD) for adapter configuration information.

`pfnGetMultisampleMethodListCb`

Pointer to the pfnGetMultisampleMethodListCb function, which UMD uses to retrieve the list of multiple-sampling methods that are used for an allocation.

`pfnQueryAdapterInfoCb2`

Pointer to the runtime's pfnQueryAdapterInfoCb2 function, which UMD uses to query the display miniport driver (KMD) for adapter information.

Remarks

The Direct3D runtime passes D3DDDI_ADAPTERCALLBACKS to UMD when it calls UMD's OpenAdapter function.
