D3DDDI_TESTCOMMANDBUFFER_COPY structure (d3dukmdt.h)
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.
Remarks
D3DDDI_TESTCOMMANDBUFFER_COPY is used to copy bytes using source and destination GPU virtual addresses.
