DXGKCB_PINFRAMEBUFFERFORSAVE callback function (d3dkmddi.h)
A kernel-mode display miniport driver calls DXGKCB_PINFRAMEBUFFERFORSAVE to pin down the entire frame buffer at once.
Syntax
DXGKCB_PINFRAMEBUFFERFORSAVE DxgkcbPinframebufferforsave;
NTSTATUS DxgkcbPinframebufferforsave(
[in] IN_CONST_HANDLE hAdapter,
[in/out] INOUT_PDXGKARGCB_PINFRAMEBUFFERFORSAVE pPinFrameBufferForSave
)
{...}
Parameters
[in] hAdapter
A handle to a display adapter. The driver provides this handle for the master/lead device in the linked display adapter (LDA) chain.
[in/out] pPinFrameBufferForSave
Pointer to a DXGKARGCB_PINFRAMEBUFFERFORSAVE structure that contains information about the frame buffer to save.
Return value
DXGKCB_PINFRAMEBUFFERFORSAVE returns STATUS_SUCCESS if the operation succeeds. Otherwise, it returns an appropriate NTSTATUS error code.
Remarks
DXGKCB_XXX functions are implemented by Dxgkrnl. To use this callback function, set the appropriate members of DXGKARGCB_PINFRAMEBUFFERFORSAVE and then call DxgkCbPinFrameBufferForSave via the DXGKRNL_INTERFACE.
See IOMMU-based GPU isolation for more information.
