D3DDDIARG_UPDATESUBRESOURCEUP structure (d3dumddi.h)
Describes info that's used to update a destination subresource region from a source system-memory region. Used by Windows Display Driver Model (WDDM) 1.3 and later user-mode display drivers.
Syntax
typedef struct D3DDDIARG_UPDATESUBRESOURCEUP {
HANDLE hResource;
UINT SubResourceIndex;
D3DDDIBOX DstBox;
const VOID *pSysMemUP;
UINT RowPitch;
UINT DepthPitch;
D3DDDIARG_COPYFLAGS Flags;
} D3DDDIARG_UPDATESUBRESOURCEUP;
Members
hResource
A handle to the destination resource to copy to.
SubResourceIndex
The index of the destination subresource to which data is to be copied.
DstBox
A destination region, of type D3DDDIBOX, of the subresource to which data is to be copied. If Flags->BoxValid is not set, the entire subresource must be updated.
pSysMemUP
A pointer to the beginning address of the source data that the pfnUpdateSubresourceUP function copies to update the destination subresource.
RowPitch
The offset, in bytes, to move to the next row of source data.
DepthPitch
The offset, in bytes, to move to the next depth slice of source data.
Flags
A D3DDDIARG_COPYFLAGS structure that specifies additional characteristics of the subresource update operation.
