View the official Windows Driver Kit DDI referenceNo description available.
The D3DDDICB_SETDISPLAYMODE structure describes the primary allocation that is used to scan out to the display.
hPrimaryAllocation [in]A D3DKMT_HANDLE data type that represents the kernel-mode handle to the primary allocation for scanning out. The Microsoft Direct3D runtime's pfnAllocateCb function returns this handle.
PrivateDriverFormatAttribute [out]A private format attribute that the user-mode display driver should use to convert the current primary surface if the pfnSetDisplayModeCb callback function returned D3DDDIERR_INCOMPATIBLEPRIVATEFORMAT.
The user-mode display driver can set the hPrimaryAllocation member in the call to pfnSetDisplayModeCb to scan out any allocation. However, the allocation must be marked as a primary (that is, the user-mode display driver must have set the Primary bit-field flag in the Flags member of the D3DDDI_ALLOCATIONINFO structure in a call to the pfnAllocateCb function to create the allocation).
