DXGK_AGP_INTERFACE structure

Description

The DXGK_AGP_INTERFACE structure contains pointers to functions in the Accelerated Graphics Port (AGP) interface, which is implemented by the display port driver.

Members

`Size`

The size, in bytes, of this structure.

`Version`

The version number of the AGP interface. Version number constants are defined in Dispmprt.h (for example, DXGK_AGP_INTERFACE_VERSION_1).

`Context`

A pointer to a context that is provided by the display port driver.

`InterfaceReference`

A pointer to an interface reference function that is implemented by the display port driver.

`InterfaceDereference`

A pointer to an interface dereference function that is implemented by the display port driver.

`AgpAllocatePool`

A pointer to the display port driver's AgpAllocatePool function.

`AgpFreePool`

A pointer to the display port driver's AgpFreePool function.

`AgpSetCommand`

A pointer to the display port driver's AgpSetCommand function.

Remarks

The display miniport driver supplies the Size and Version members of this structure, and then calls DxgkCbQueryServices, which fills in the remaining members of this structure.
