  • [アーティクル]

The D3DDDI_TESTCOMMANDBUFFER_COPY structure describes a copy operation for a test command buffer for kernel-mode testing.

Syntax

typedef struct _D3DDDI_TESTCOMMANDBUFFER_COPY {
  D3DKMT_ALIGN64 D3DGPU_VIRTUAL_ADDRESS SrcAddress;
  D3DKMT_ALIGN64 D3DGPU_VIRTUAL_ADDRESS DstAddress;
  UINT                                  NumBytes;
} D3DDDI_TESTCOMMANDBUFFER_COPY;

Members

SrcAddress

The source GPU virtual address for the copy operation.

DstAddress

The destination GPU virtual address for the copy operation.

NumBytes

The number of bytes to copy. NumBytes must be a multiple of 4.
