D3DDDICB_CREATECONTEXT structure (d3dumddi.h)

The D3DDDICB_CREATECONTEXT structure describes a context to create.

Syntax

typedef struct _D3DDDICB_CREATECONTEXT {
  [in]  UINT                      NodeOrdinal;
  [in]  UINT                      EngineAffinity;
  [in]  D3DDDI_CREATECONTEXTFLAGS Flags;
  [in]  VOID                      *pPrivateDriverData;
  [in]  UINT                      PrivateDriverDataSize;
  [out] HANDLE                    hContext;
  [out] VOID                      *pCommandBuffer;
  [out] UINT                      CommandBufferSize;
  [out] D3DDDI_ALLOCATIONLIST     *pAllocationList;
  [out] UINT                      AllocationListSize;
  [out] D3DDDI_PATCHLOCATIONLIST  *pPatchLocationList;
  [out] UINT                      PatchLocationListSize;
        D3DGPU_VIRTUAL_ADDRESS    CommandBuffer;
} D3DDDICB_CREATECONTEXT;

Members

[in] NodeOrdinal

The zero-based index for the node that the context is scheduled on.

[in] EngineAffinity

The zero-based index for the engine, within the node that NodeOrdinal specifies, that the context can run in.

[in] Flags

A D3DDDI_CREATECONTEXTFLAGS structure that indicates, in bit-field flags, how to create the context.

[in] pPrivateDriverData

A pointer to private data that is passed to a display miniport driver.

[in] PrivateDriverDataSize

The size, in bytes, of the private data that pPrivateDriverData points to.

[out] hContext

A handle to the context that the pfnCreateContextCb function creates.

[out] pCommandBuffer

A pointer to the first command buffer for the created context.

[out] CommandBufferSize

The size, in bytes, of the first command buffer for the created context, which pCommandBuffer points to.

[out] pAllocationList

An array of D3DDDI_ALLOCATIONLIST structures for the first allocation list for the created context.

[out] AllocationListSize

The number of elements in the allocation-list array that pAllocationList specifies.

[out] pPatchLocationList

An array of D3DDDI_PATCHLOCATIONLIST structures for the first patch-location list for the created context.

[out] PatchLocationListSize

The number of elements in the patch-location-list array that pPatchLocationList specifies.

CommandBuffer

This member is reserved and should be set to zero.

This member is available beginning with Windows 7.
