Updates subresources with a heap-allocating implementation.

Syntax

UINT64 inline UpdateSubresources(
  _In_ ID3D12GraphicsCommandList *pCmdList,
  _In_ ID3D12Resource            *pDestinationResource,
  _In_ ID3D12Resource            *pIntermediate,
       UINT64                    IntermediateOffset,
  _In_ UINT                      FirstSubresource,
  _In_ UINT                      NumSubresources,
  _In_ D3D12_SUBRESOURCE_DATA    *pSrcData
);

Parameters

pCmdList [in]

Type: ID3D12GraphicsCommandList*

A pointer to the ID3D12GraphicsCommandList interface for the command list.

pDestinationResource [in]

Type: ID3D12Resource*

A pointer to the ID3D12Resource interface that represents the destination resource.

pIntermediate [in]

Type: ID3D12Resource*

A pointer to the ID3D12Resource interface that represents the intermediate resource.

IntermediateOffset

Type: UINT64

The offset, in bytes, to the intermediate resource.

FirstSubresource [in]

Type: UINT

The index of the first subresource in the resource. The range of valid values is 0 to D3D12_REQ_SUBRESOURCES.

NumSubresources [in]

Type: UINT

The number of subresources in the resource. The range of valid values is 0 to (D3D12_REQ_SUBRESOURCES - FirstSubresource).

pSrcData [in]

Type: D3D12_SUBRESOURCE_DATA*

Pointer to an array (of length NumSubresources) of pointers to D3D12_SUBRESOURCE_DATA structures containing descriptions of the subresource data used for the update.

Return value

Type: UINT64

The size, in bytes, of the buffer.
